Returns the FunctionFactory for the given Function name.

Specified by:

getFunctionFactory in interface OperatorSource

Parameters:

name - The name of the Function

Returns:

Operator Factory.

getOperandFactory

public OperatorFactory<Operand> getOperandFactory(java.lang.String name)

Description copied from interface: OperatorSource

Returns the factory for the given Operand.

Specified by:

getOperandFactory in interface OperatorSource
