Constructors

QueryablePropertyGroupDescriptionBase()

Declaration
protected QueryablePropertyGroupDescriptionBase()

Properties

Gets a value indicating whether grouped data should be processed before handing it over to the engine.

Declaration
protected override bool NeedsProcessing { get; }
Property Value
System.Boolean

true if should process; otherwise, false.
Overrides

Methods

CloneCore(Cloneable)

Creates a deep copy of this group description by copying core properties including sort order and group comparer. This method ensures that cloned instances maintain their grouping and sorting configuration independently.

Declaration
protected override void CloneCore(Cloneable source)
Parameters
Cloneable source

The source group description to clone from.
Overrides
Remarks

Notes to Inheritors If you derive from Cloneable, you may need to override this method to copy all properties. It is essential that all implementations call the base implementation of this method (if you don't call base you should manually copy all needed properties including base properties).

CreateGroupKeyExpression(IEnumerable<Expression>)

Creates the group key expression.

Declaration
protected override Expression CreateGroupKeyExpression(IEnumerable<Expression> valueExpressions)
Parameters
System.Collections.Generic.IEnumerable<System.Linq.Expressions.Expression> valueExpressions

Value expressions used for generating group key.
Returns
System.Linq.Expressions.Expression

Expression that creates group key for the given item.
Overrides

CreateGroupKeyValuesExpressions(ParameterExpression)

Creates value expressions for values that will be used for generating group key expression.

Declaration
protected override IEnumerable<Expression> CreateGroupKeyValuesExpressions(ParameterExpression itemExpression)
Parameters
System.Linq.Expressions.ParameterExpression itemExpression

The parameter expression, which will be used for grouping.
Returns
System.Collections.Generic.IEnumerable<System.Linq.Expressions.Expression>

Value expressions.
Overrides

GetDisplayName()

Gets the display-friendly name.

Declaration
protected override string GetDisplayName()
Returns
System.String

A System.String name.
Overrides

GetUniqueName()

Returns the member name for this description.

Declaration
public override string GetUniqueName()
Returns
System.String

Overrides
