Method Details

getName

public String getName()

Description copied from class: Function

Get the name of the function. This method must be implemented in all subclasses.

Specified by:

getName in class Function

Returns:

the name of the function, as used in XSL expressions, but excluding its namespace prefix

getDataType

public int getDataType()

Determine the data type of the expression

Specified by:

getDataType in class Expression

Returns:

Value.STRING

simplify

public Expression simplify()
                    throws XPathException

Validate and simplify

Overrides:

simplify in class Expression

Returns:

the simplified expression

Throws:

XPathException

evaluateAsString

public String evaluateAsString(Context context)
                        throws XPathException

Evaluate the expression in a string context

Overrides:

the value of the expression, evaluated in the current context

Throws:

XPathException

evaluate

public Value evaluate(Context c)
               throws XPathException

Evaluate in a general context

Specified by:

evaluate in class Expression

Parameters:

c - The context in which the expression is to be evaluated

Returns:

the value of the expression, evaluated in the current context

Throws:

XPathException

getDependencies

public int getDependencies()

Determine which aspects of the context the expression depends on. The result is a bitwise-or'ed value composed from constants such as Context.VARIABLES and Context.CURRENT_NODE

Specified by:

getDependencies in class Expression

reduce

public Expression reduce(int dep,
 Context c)
                  throws XPathException

Remove dependencies.

Specified by:

reduce in class Expression

Parameters:

dep - The dependencies to be removed, e.g. Context.VARIABLES

c - The context to be used for the partial evaluation

Returns:

a new expression (or Value) that does not have any of the specified dependencies
