public StructuredQName getFunctionQName()
getFunctionQName in class ExtensionFunctionDefinitionpublic int getMinimumNumberOfArguments()
getMinimumNumberOfArguments in class ExtensionFunctionDefinitionpublic int getMaximumNumberOfArguments()
getMaximumNumberOfArguments in class ExtensionFunctionDefinitionpublic SequenceType[] getArgumentTypes()
getArgumentTypes in class ExtensionFunctionDefinitiongetMaximumNumberOfArguments(); however for functions
that allow a variable number of arguments, the array can be smaller than this, with the last
entry in the array providing the required type for all the remaining arguments.public SequenceType getResultType(SequenceType[] argumentTypes)
getResultType in class ExtensionFunctionDefinitionargumentTypes - the static types of the arguments to the function.
This is provided so that a more precise result type can be returned in the common
case where the type of the result depends on the type of the first argument.
