public final class AggregationFunctionExpression
extends TypedExpression

A TypedExpression that represents an aggregation function. With an AggregationFunctionExpression, you can aggregate measure values over specified dimension members. You specify the dimension members with an AggregateOverMembersClause. You can use an AggregationFunctionExpression as the Expression for an MdmCustomMember of an MdmModel.


Constructor Summary
AggregationFunctionExpression(java.lang.String functionName, FunctionArgument arg, AggregateOverClause overClause)
          Creates an AggregationFunctionExpression that resolves to the aggregation function with the function argument and OVER clause.
AggregationFunctionExpression(java.lang.String functionName, java.util.List<FunctionArgument> args, AggregateOverClause overClause)
          Creates an AggregationFunctionExpression that resolves to the aggregation function with the function arguments and OVER clause.

 

Method Summary
 FunctionArgument[] getArguments()
          Gets the function arguments that are associated with this AggregationFunctionExpression.
 FunctionDescriptor getFunctionDescriptor()
          Gets the function descriptor that is associated with this AggregationFunctionExpression.
 java.lang.String getFunctionName()
          Gets the name of the aggregation function that this AggregationFunctionExpression represents.
 AggregateOverClause getOverClause()
          Gets the AggregateOverClause that is associated with this AggregationFunctionExpression.
 java.lang.Object visit(SyntaxObjectVisitor visitor, java.lang.Object context)
          Calls the visitAggregationFunctionExpression method of the SyntaxObjectVisitor and passes that method this AggregationFunctionExpression and an Object.

Constructor Detail

AggregationFunctionExpression

public AggregationFunctionExpression(java.lang.String functionName,
                                     FunctionArgument arg,
                                     AggregateOverClause overClause)
Creates an AggregationFunctionExpression that resolves to the aggregation function with the function argument and OVER clause.
Parameters:
functionName - A String that contains the name of the function.
arg - A FunctionArgument that is the only argument of the function.
overClause - An AggregateOverClause that specifies the values to include in the aggregation.

AggregationFunctionExpression

public AggregationFunctionExpression(java.lang.String functionName,
                                     java.util.List<FunctionArgument> args,
                                     AggregateOverClause overClause)
Creates an AggregationFunctionExpression that resolves to the aggregation function with the function arguments and OVER clause.
Parameters:
functionName - A String that contains the name of the function.
args - A List of FunctionArgument objects that are the arguments to the function.
overClause - An AggregateOverClause that specifies the values to include in the aggregation.

Method Detail

visit

public java.lang.Object visit(SyntaxObjectVisitor visitor,
                              java.lang.Object context)
