QueryablePropertyAggregateDescriptionBase()
Declaration
protected QueryablePropertyAggregateDescriptionBase()Properties
AggregateFunction
Gets or sets the aggregate function that will be used for summary calculation.
Declaration
public QueryableAggregateFunction AggregateFunction { get; set; }Property Value
|
QueryableAggregateFunction
Aggregation function. |
AggregateMethodName
Gets the name of the aggregate method on the ExtensionMethodsType that will be used for aggregation.
Declaration
protected override string AggregateMethodName { get; }Property Value
|
System.String
The name of the aggregate method that will be used. |
Overrides
DataType
Provides the data type of the aggregate description.
Declaration
protected Type DataType { get; }Property Value
|
System.Type
|
IgnoreNullValues
Gets or sets a value that determines whether the QueryableAggregateFunctions of this QueryablePropertyAggregateDescriptionBase will ignore null values when calculating the result.
Declaration
public bool IgnoreNullValues { get; set; }Property Value
|
System.Boolean
|
PropertyName
Gets or sets a value identifying a property on the grouped items.
Declaration
public string PropertyName { get; set; }Property Value
|

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).
CreateAggregateExpression(Expression, String)
Creates the aggregate expression.
Declaration
protected override Expression CreateAggregateExpression(Expression enumerableExpression, string aggregatedValueName)Parameters
|
System.Linq.Expressions.Expression
enumerableExpression
The grouping expression. |
|
System.String
aggregatedValueName
TODO: finish this. |
Returns
|
System.Linq.Expressions.Expression
|
Overrides
CreateAggregateValueExpression(ParameterExpression)
Creates the aggregate expression.
Declaration
protected override Expression CreateAggregateValueExpression(ParameterExpression itemExpression)Parameters
|
System.Linq.Expressions.ParameterExpression
itemExpression
TODO: finish this. |
Returns
|
System.Linq.Expressions.Expression
|
Overrides

Overrides
GetDisplayName()
Gets the display-friendly name.
Declaration
protected override string GetDisplayName()Returns
|
