public StructuredQName getFunctionQName()
getFunctionQName in class ExtensionFunctionDefinitionpublic int getMinimumNumberOfArguments()
The default implementation returns the number of items in the result of calling
getArgumentTypes()
getMinimumNumberOfArguments in class ExtensionFunctionDefinitionpublic int getMaximumNumberOfArguments()
The default implementation returns the value of getMinimumNumberOfArguments()
getMaximumNumberOfArguments in class ExtensionFunctionDefinitionpublic boolean trustResultType()
trustResultType in class ExtensionFunctionDefinitionpublic SequenceType[] getArgumentTypes()
This method must be implemented in all subtypes.
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[] suppliedArgumentTypes)
This method must be implemented in all subtypes.
getResultType in class ExtensionFunctionDefinitionsuppliedArgumentTypes - the static types of the supplied 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 types of the arguments.
