Class QueryProviderBase<RowType>

This is the base class for ArchiveProviders that use a database query to get their data. Other ways of making archive providers exist, such as TypedInMemoryProviderBase, where the data source is something else and the data are simply buffered by the base class.

Methods

AcceptRow(SoDataReader)

Decide whether the current row of the passed-in _reader should be accepted or not. If false is returned, this row is skipped by the base class and never seen by the client. This method is called very early, before any ArchiveRow population, and can only rely on fields directly accessible in the Reader. On the other hand, that makes is reasonably cheap to skip rows.

If you implement this method, you MUST aslo implement RequiredPhaseOneFields() to tell the query rewriter about fields you need, otherwise they will not be present in the phase one query and you will crash.

Declaration

protected virtual bool AcceptRow(SoDataReader reader)

Parameters

Type	Name	Description
SoDataReader	reader

Returns

Type	Description
bool	true if the current row should be further processed

Remarks

Classes derived from this class will generally have the following structure:

AddInhibitedStyleHint(string)

Add a style hint to the list of style hints that should be hidden (not be present in the final result rows)

Declaration

public void AddInhibitedStyleHint(string stylehint)

Parameters

Type	Name	Description
string	stylehint

Remarks

Classes derived from this class will generally have the following structure:

Close()

Call this method after the last desired row has been read; this gives the provider the chance to close and free any underlying queries.

Declaration

public virtual void Close()

Remarks

Classes derived from this class will generally have the following structure:

ConvertToTypedRows(IEnumerable<ArchiveRow>)

Convert a generic ArchiveRow into some typed subclass, provided the passed-in rows are actually castable

Declaration

protected IEnumerable<RowType> ConvertToTypedRows(IEnumerable<ArchiveRow> genericRows)

Parameters

Type	Name	Description
IEnumerable<ArchiveRow>	genericRows	Enumerable of generic rows that are actually a typed subclass

Returns

Type	Description
IEnumerable<RowType>	Enumerable of case, typed rows

Remarks

Classes derived from this class will generally have the following structure:

CreateArchiveRow(string, int)

Create the archive row object. Providers that offer a strongly typed interface should override this method and create their strongly typed row instead of leaving this generic implementation to make the generic one.

Declaration

protected virtual RowType CreateArchiveRow(string entityName, int primaryKey)

Parameters

Type	Name	Description
string	entityName	name of entity represented by this row
int	primaryKey	Primary key value of this row

Returns

Type	Description
RowType	Empty row

Remarks

Classes derived from this class will generally have the following structure:

GetAllExtenders()

Declaration

public IEnumerable<IArchiveExtender> GetAllExtenders()

Returns

Type	Description
IEnumerable<IArchiveExtender>

Remarks

Classes derived from this class will generally have the following structure:

GetAvailableEntities()

Get all entities declared by this provider and its extenders

Declaration

public virtual List<ArchiveRowTypeInfo> GetAvailableEntities()

Returns

Type	Description
List<ArchiveRowTypeInfo>	List of available entities

Remarks

Classes derived from this class will generally have the following structure:

GetEntityName(SoDataReader)

Return the entity name of the current row. The default implementation statically assigns the name of the first registered entity to all rows. Subclasses may override this method if they wish to set other entity names, possibly dependent on data.

Declaration

protected virtual string GetEntityName(SoDataReader _reader)

Parameters

Type	Name	Description
SoDataReader	_reader	_reader with the current data row

Returns

Type	Description
string	Entity name

Remarks

Classes derived from this class will generally have the following structure:

GetFinalRowCount()

Actual number of rows in query, valid only when HaveReadToEnd = true; otherwise you get -1

Declaration

protected int GetFinalRowCount()

Returns

Type	Description
int

Remarks

Classes derived from this class will generally have the following structure:

GetReader(string)

Start the reader and return an IDataReader (which, as we remember, also inherits IDataRecord for access to individual data fields). This provides an alternative, more generic and more standards-based interface to data. Use either GetRows or GetReader on any particular archive provider instance.

Declaration

public virtual IDataReader GetReader(string options)

Parameters

Type	Name	Description
string	options

Returns

Type	Description
IDataReader

Remarks

Classes derived from this class will generally have the following structure:

GetResultInformation()

Get additional information about the result, such as row count or other optional items. This method should be called some time after GetRows, but before Close. Delaying calls to this method as long as possible will give its (asynchronous) internal counterpart more time to complete and lessen the response-time impact of calling it.

Declaration

public ArchiveResultInformation GetResultInformation()

Returns

Type	Description
ArchiveResultInformation

Remarks

Classes derived from this class will generally have the following structure:

GetRows(string)

Pass the built-up query to the database; perform paging; and pass populated rows back to the caller.

Declaration

public virtual IEnumerable<ArchiveRow> GetRows(string options)

Parameters

Type	Name	Description
string	options

Returns

Type	Description
IEnumerable<ArchiveRow>

Remarks

This method calls the following derived-class overrides, in the following order:

HandleDynamicExtenders(IArchiveExtender)

Declaration

protected virtual void HandleDynamicExtenders(IArchiveExtender dynamicTree)

Parameters

Type	Name	Description
IArchiveExtender	dynamicTree

Remarks

Classes derived from this class will generally have the following structure:

InnerMapFields()

Override this method to map query fields to columns, add additional return fields to the query, and set up custom restriction handling

Declaration

public virtual void InnerMapFields()

Remarks

Classes derived from this class will generally have the following structure:

InnerSetRestriction(ArchiveRestrictionInfo[])

Override this method to implement custom processing during SetRestriction, without killing the default implementation

Declaration

public virtual bool InnerSetRestriction(ArchiveRestrictionInfo[] restrictions)

Parameters

Type	Name	Description
ArchiveRestrictionInfo[]	restrictions	Incoming array of restrictions

Returns

Type	Description
bool	True if at least one active restriction matched a known column and was processed

Remarks

Classes derived from this class will generally have the following structure:

OverrideValueIfBlank(ArchiveRow, string, string)

Declaration

protected bool OverrideValueIfBlank(ArchiveRow row, string columnToOverride, string alternativeSource)

Parameters

Type	Name	Description
ArchiveRow	row
string	columnToOverride
string	alternativeSource

Returns

Type	Description
bool

Remarks

Classes derived from this class will generally have the following structure:

PostProcessQuery()

This method is called after ModifyQuery has been called on all extenders, but before the query is executed. It is used for processing that needs the query to be 'complete' from the extenders, and gives the opportunity to tweak it, for instance by adding return fields needed for some particular functionality.

Declaration

public virtual void PostProcessQuery()

Remarks

Classes derived from this class will generally have the following structure:

PostProcessRow(SoDataReader, ArchiveRow)

This method is a hook that can be used by derived classes to post-process rows. It is called after all extenders have fetched their data and populated the row.

Declaration

protected virtual void PostProcessRow(SoDataReader _reader, ArchiveRow row)

Parameters

Type	Name	Description
SoDataReader	_reader
ArchiveRow	row

Remarks

Classes derived from this class will generally have the following structure:

RegisterEntity(ArchiveRowTypeInfo)

Declaration

protected ArchiveRowTypeInfo RegisterEntity(ArchiveRowTypeInfo entity)

Parameters

Type	Name	Description
ArchiveRowTypeInfo	entity	Entity to register

Returns

Type	Description
ArchiveRowTypeInfo	The same entity, so you can go on doing things to it

Remarks

Classes derived from this class will generally have the following structure:

RequiredPhaseOneFields()

Return the FieldInfo fields needed by AcceptRow(SoDataReader), so that the query rewriter does not drop them. Implement this method IFF you implement AcceptRow.

Declaration

protected virtual FieldInfo[] RequiredPhaseOneFields()

Returns

Type	Description
FieldInfo[]

Remarks

Classes derived from this class will generally have the following structure:

SetDesiredColumns(params string[])

Set the desired columns, by saving them in an internal data structures. Duplicates are gracefully ignored.

Parameters

Type	Name	Description
string[]	entities	Names of desired entities

Remarks

Classes derived from this class will generally have the following structure:

SetOrderBy(ArchiveOrderByInfo[])

Set the order by parameters. This method sets the order by parameters of this provider, as well as invoking the same call on all known extenders. Recursion will take it to the bottom. This method actually only saves the orderby specification for use during query processing. Any column name overrides are processed, i.e., replaced with the original inner names, so that the inner providers do not see the overrides.

Declaration

public override void SetOrderBy(ArchiveOrderByInfo[] orderBy)

Parameters

Type	Name	Description
ArchiveOrderByInfo[]	orderBy	Array of order by criteria

Overrides

ExtensibleColumnsBase.SetOrderBy(ArchiveOrderByInfo[])

int	pageNumber	0-based page number

Remarks

Classes derived from this class will generally have the following structure:

SetRestriction(params ArchiveRestrictionInfo[])

Set the restriction by calling the base class and InnerSetRestriction; take this opportunity to note that a restriction has actually been set, so we can report cases of totally missing restrictions (which is not acceptable as it might end up fetching the whole database)

Declaration

public override bool SetRestriction(params ArchiveRestrictionInfo[] restrictions)

Parameters

Type	Name	Description
ArchiveRestrictionInfo[]	restrictions

Returns

Type	Description
bool

Overrides

ExtensibleColumnsBase.SetRestriction(params ArchiveRestrictionInfo[])
