Class RegistryRows

public class RegistryRows : TableRowsBase, INestedPersist, IEnumerable<INestedPersist>, ISoCollection, IList, ICollection, IEnumerable, INotifyCollectionChanged, IBindingList

Remarks

Row collections can be created in several ways.

Use the static CreateNew() method to create a new, empty collection. You can then add objects of type RegistryRow to it, and use methods like to operate on the whole collection.
You can create a (nested) RegistryRows RegistryRows.CustomSearch object to obtain a query pre-populated with the correct tableinfo and return fields. This query can be modified with restrictions, etc. Then, use the static GetFromCustomSearch(RegistryRows.CustomSearch) method to apply the query to the database and obtain the result as a Rows object, with one item for each table row that matched your query.
For each non-unique index defined for the table, there is a corresponding GetFromIdx method to make retrieving data via the indexes easy.

Unique indexes are handled through the RegistryRow object directly, which has nested classes and GetFromIdx methods for each unique index. Similarly, there is a GetFromReader(SoDataReader, RegistryTableInfo) method to retrieve the results of queries that return more than one row (this method will iterate over the reader to fetch ALL results, so beware of fetching huge result sets).

Properties

Item[Int32]

Get a RegistryRow given its index in the collection.

Declaration

public RegistryRow this[int index] { get; }

Parameters

Type	Name	Description
Int32	index	Index of the RegistryRow in the collection

Property Value

Type	Description
RegistryRow

Methods

Add(RegistryRow)

Add one RegistryRow to the collection.

Declaration

public int Add(RegistryRow row)

Parameters

Type	Name	Description
RegistryRow	row	An instance of RegistryRow to be added to the collection.

Returns

Type	Description
Int32	The index of the added RegistryRow.

AddNew()

Add a new instance of RegistryRow added to the collection.

Declaration

public RegistryRow AddNew()

Returns

Type	Description
RegistryRow	A new instance of RegistryRow added to the collection.

AddRange(IEnumerable<RegistryRow>)

Add a range of RegistryRow to the collection.

Declaration

public RegistryRows AddRange(IEnumerable<RegistryRow> rows)

Parameters

Type	Name	Description
IEnumerable<RegistryRow>	rows

Returns

Type	Description
RegistryRows	The updated RegistryRows collection object.

CreateChild()

Create a new instance of RegistryRow

Declaration

protected override TableRowBase CreateChild()

Returns

Type	Description
TableRowBase	New instance of RegistryRow

Overrides

TableRowsBase.CreateChild()

CreateNew()

Create a new instance of the RegistryRows object. This collection will contain no rows.

Declaration

public static RegistryRows CreateNew()

Returns

Type	Description
RegistryRows	A new instance of the RegistryRows object.

Find(Predicate<RegistryRow>)

Apply the predicate to each element of the collection and return the first row that matches; if no match then return null

Declaration

public RegistryRow Find(Predicate<RegistryRow> condition)

Parameters

Type	Name	Description
Predicate<RegistryRow>	condition

Returns

Type	Description
RegistryRow

FindAll(Predicate<RegistryRow>)

Return a new collection that contains only those elements that match the condition. Elements are shared, not clones! of the original collection

Declaration

public RegistryRows FindAll(Predicate<RegistryRow> condition)

Parameters

Type	Name	Description
Predicate<RegistryRow>	condition

Returns

Type	Description
RegistryRows

ForEach(Action<RegistryRow>)

Method that iterates over all members and applies the action parameter to each of them

Declaration

public void ForEach(Action<RegistryRow> whatToDo)

Parameters

Type	Name	Description
Action<RegistryRow>	whatToDo

GetFromCustomSearch(RegistryRows.CustomSearch)

Create a new instance of the RegistryRows object, and populate it with data from a custom search. If the search returns no results, an empty collection will be returned; if the result contains rows, a collection of RegistryRow objects representing each row will be returned.

Declaration

public static RegistryRows GetFromCustomSearch(RegistryRows.CustomSearch query)

Parameters

Type	Name	Description
RegistryRows.CustomSearch	query	The custom search to execute against the database

Returns

Type	Description
RegistryRows	A new instance of the RegistryRows object, reflecting the result of the query.

GetFromReader(SoDataReader, RegistryTableInfo)

Create a new instance of the RegistryRows object, and populate it with data from a reader. If the search returns no results, an empty collection will be returned; if the result contains rows, a collection of RegistryRow objects representing each row will be returned.

Note that the internal logic starts by calling reader.Read(), which is correct if you hand the method the result of an ExecuteReader(), but if the reader has already been advanced one or more rows, the current row will be skipped and collection population will start with the next row.

Declaration

public static RegistryRows GetFromReader(SoDataReader reader, RegistryTableInfo tableInfo)

Parameters

Type	Name	Description
SoDataReader	reader	SoDataReader positioned to a valid database row.
RegistryTableInfo	tableInfo	RegistryTableInfo instance used in the query that is the source of the reader. The fields used from the reader will be those owned by this tableinfo object.
