Class SourceRows

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

Declaration

public SourceRow this[int index] { get; }

Parameters

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

Property Value

Type	Description
SourceRow

Methods

Add(SourceRow)

Add one SourceRow to the collection.

Declaration

public int Add(SourceRow row)

Parameters

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

Returns

Type	Description
Int32	The index of the added SourceRow.

AddNew()

Add a new instance of SourceRow added to the collection.

Declaration

public SourceRow AddNew()

Returns

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

AddRange(IEnumerable<SourceRow>)

Add a range of SourceRow to the collection.

Declaration

public SourceRows AddRange(IEnumerable<SourceRow> rows)

Parameters

Type	Name	Description
IEnumerable<SourceRow>	rows

Returns

Type	Description
SourceRows	The updated SourceRows collection object.

CreateChild()

Create a new instance of SourceRow

Declaration

protected override TableRowBase CreateChild()

Returns

Type	Description
TableRowBase	New instance of SourceRow

Overrides

TableRowsBase.CreateChild()

CreateNew()

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

Declaration

public static SourceRows CreateNew()

Returns

Type	Description
SourceRows	A new instance of the SourceRows object.

Find(Predicate<SourceRow>)

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

Declaration

public SourceRow Find(Predicate<SourceRow> condition)

Parameters

Type	Name	Description
Predicate<SourceRow>	condition

Returns

Type	Description
SourceRow

FindAll(Predicate<SourceRow>)

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

Declaration

public SourceRows FindAll(Predicate<SourceRow> condition)

Parameters

Type	Name	Description
Predicate<SourceRow>	condition

Returns

Type	Description
SourceRows

ForEach(Action<SourceRow>)

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

Declaration

public void ForEach(Action<SourceRow> whatToDo)

Parameters

Type	Name	Description
Action<SourceRow>	whatToDo

GetFromCustomSearch(SourceRows.CustomSearch)

Create a new instance of the SourceRows 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 SourceRow objects representing each row will be returned.

Declaration

public static SourceRows GetFromCustomSearch(SourceRows.CustomSearch query)

Parameters

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

Returns

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

GetFromReader(SoDataReader, SourceTableInfo)

Create a new instance of the SourceRows 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 SourceRow 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 SourceRows GetFromReader(SoDataReader reader, SourceTableInfo tableInfo)

Parameters

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