Constructors

QueryableDoubleGroupDescription()

Initializes a new instance of the QueryableDoubleGroupDescription class.

Declaration
public QueryableDoubleGroupDescription()

Properties

NeedsProcessing

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

Step

Declaration
public double Step { get; set; }
Property Value
System.Double

Methods

CloneCore(Cloneable)

Makes the instance a clone (deep copy) of the specified Cloneable.

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

The object to clone.
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

CreateInstanceCore()

When implemented in a derived class, creates a new instance of the Cloneable derived class.

Declaration
protected override Cloneable CreateInstanceCore()
Returns
Cloneable

New instance for cloning.
Overrides
Remarks

Do not call this method directly (except when calling base in an implementation). This method is called internally by the Clone() method whenever a new instance of the Cloneable is created. Notes to Inheritors. Every Cloneable derived class must implement this method. A typical implementation is to simply call the default constructor and return the result.

GetAllNames(IEnumerable<Object>, IEnumerable<Object>)

Returns all possible group keys for this instance.

Declaration
protected override IEnumerable<object> GetAllNames(IEnumerable<object> uniqueNames, IEnumerable<object> parentGroupNames)
Parameters
System.Collections.Generic.IEnumerable<System.Object> uniqueNames

Enumeration of all unique group keys that were discovered after grouping.
System.Collections.Generic.IEnumerable<System.Object> parentGroupNames

Enumeration of all parent groups.
Returns
System.Collections.Generic.IEnumerable<System.Object>

Returns all possible group keys for this instance.
Overrides
