Class EjscriptRows

public class EjscriptRows : 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 EjscriptRow to it, and use methods like to operate on the whole collection.
You can create a (nested) EjscriptRows EjscriptRows.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(EjscriptRows.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 EjscriptRow object directly, which has nested classes and GetFromIdx methods for each unique index. Similarly, there is a GetFromReader(SoDataReader, EjscriptTableInfo) 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).

public EjscriptRow this[int index] { get; }

Parameters

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

Property Value

Type	Description
EjscriptRow

Methods

Add(EjscriptRow)

Add one EjscriptRow to the collection.

Declaration

public int Add(EjscriptRow row)

Parameters

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

Returns

Type	Description
Int32	The index of the added EjscriptRow.

AddNew()

Add a new instance of EjscriptRow added to the collection.

Declaration

public EjscriptRow AddNew()

Returns

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

AddRange(IEnumerable<EjscriptRow>)

Add a range of EjscriptRow to the collection.

Declaration

public EjscriptRows AddRange(IEnumerable<EjscriptRow> rows)

Parameters

Type	Name	Description
IEnumerable<EjscriptRow>	rows

Returns

Type	Description
EjscriptRows	The updated EjscriptRows collection object.

CreateChild()

Create a new instance of EjscriptRow

Declaration

protected override TableRowBase CreateChild()

Returns

Type	Description
TableRowBase	New instance of EjscriptRow

Overrides

TableRowsBase.CreateChild()

CreateNew()

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

Declaration

public static EjscriptRows CreateNew()

Returns

Type	Description
EjscriptRows	A new instance of the EjscriptRows object.

Find(Predicate<EjscriptRow>)

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

Declaration

public EjscriptRow Find(Predicate<EjscriptRow> condition)

Parameters

Type	Name	Description
Predicate<EjscriptRow>	condition

Returns

Type	Description
EjscriptRow

FindAll(Predicate<EjscriptRow>)

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

Declaration

public EjscriptRows FindAll(Predicate<EjscriptRow> condition)

Parameters

Type	Name	Description
Predicate<EjscriptRow>	condition

Returns

Type	Description
EjscriptRows

ForEach(Action<EjscriptRow>)

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

Declaration

public void ForEach(Action<EjscriptRow> whatToDo)

Parameters

Type	Name	Description
Action<EjscriptRow>	whatToDo

GetFromCustomSearch(EjscriptRows.CustomSearch)

Create a new instance of the EjscriptRows 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 EjscriptRow objects representing each row will be returned.

Declaration

public static EjscriptRows GetFromCustomSearch(EjscriptRows.CustomSearch query)

Parameters

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

Returns

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

GetFromIdxHierarchyId(Int32)

Create a new instance of the EjscriptRow object, by querying the database table via the index 'IDXEjscriptHierarchy_id'. This method is intended to make it easy to use efficient queries that match a database index.

Declaration

public static EjscriptRows GetFromIdxHierarchyId(int hierarchyId)

Parameters

Type	Name	Description
Int32	hierarchyId

Returns

Type	Description
EjscriptRows	Row object that represents the result of the search. will be true if the query did not match any row in the table

Remarks

This method represents one of the unique indexes on the Ejscript table. Non-unique indexes have corresponding inner classes and methods in the EjscriptRows collection, since they may return more than one row.

GetFromIdxIncludeId(String)

Create a new instance of the EjscriptRow object, by querying the database table via the index 'IDXEjscriptInclude_id'. This method is intended to make it easy to use efficient queries that match a database index.

Declaration

public static EjscriptRows GetFromIdxIncludeId(string includeId)

Parameters

Type	Name	Description
String	includeId

Returns

Type	Description
EjscriptRows	Row object that represents the result of the search. will be true if the query did not match any row in the table

Remarks

GetFromReader(SoDataReader, EjscriptTableInfo)

Create a new instance of the EjscriptRows 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 EjscriptRow 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 EjscriptRows GetFromReader(SoDataReader reader, EjscriptTableInfo tableInfo)

Parameters

Type	Name	Description
SoDataReader	reader	SoDataReader positioned to a valid database row.
EjscriptTableInfo	tableInfo	EjscriptTableInfo 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.
