Method Detail

isSubstringMatchingFunction

public boolean isSubstringMatchingFunction()

Description copied from class: CollatingFunctionFixed

Ask whether this function needs a collation that can handle substring matching

Overrides:

isSubstringMatchingFunction in class CollatingFunctionFixed

Returns:

true in the case of functions such as contains() and starts-with() where substring matching is required. Returns false by default;

call

public StringValue call(XPathContext context,
                        Sequence[] arguments)
                 throws XPathException

Evaluate the expression

Parameters:

context - the dynamic evaluation context

arguments - the values of the arguments, supplied as Sequences

Returns:

the result of the evaluation, in the form of a Sequence

Throws:

XPathException - if a dynamic error occurs during the evaluation of the expression

getCompilerName

public java.lang.String getCompilerName()

Description copied from class: SystemFunction

Get the (local) name of a class that can be used to generate bytecode for this system function

Overrides:

getCompilerName in class SystemFunction

Returns:

the name of a bytecode generation class, or null if there is no bytecode support for this function
