                                         FunctionParameterType... parameterTypes)

Construct an instance with the given function templates where the position of each function template in the given array corresponds to the arity of the function template. The array must be padded with leading nulls where there is no overloaded form corresponding to lower arities.

Parameters:

name -

functions - the function templates to delegate to,

type -

Description copied from class: AbstractSqmFunctionDescriptor

Return an SQM node or subtree representing an invocation of this function with the given arguments. This method may be overridden in the case of function descriptors that wish to customize creation of the node.

Specified by:

generateSqmFunctionExpression in class AbstractSqmFunctionDescriptor

Parameters:

arguments - the arguments of the function invocation

impliedResultType - the function return type as inferred from its usage

getArgumentListSignature

public String getArgumentListSignature()

Overrides:

getArgumentListSignature in class AbstractSqmFunctionDescriptor

setArgumentListSignature

public void setArgumentListSignature(String argumentListSignature)

getFunction

public SqmFunctionDescriptor getFunction(int argumentCount)
