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
true if should process; otherwise, false.
Overrides
Step
Gets or sets the size of the generated DoubleGroups.
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
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
valueExpressions
IEnumerable<Expression>
Value expressions used for generating group key.
Returns
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
itemExpression
The parameter expression, which will be used for grouping.
Returns
IEnumerable<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
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
uniqueNames
IEnumerable<object>
Enumeration of all unique group keys that were discovered after grouping.
parentGroupNames
IEnumerable<object>
Enumeration of all parent groups.
Returns
IEnumerable<object>
Returns all possible group keys for this instance.
