Constructor Detail

UnparsedEntityURI


public UnparsedEntityURI()
Method Detail

getName


public java.lang.String getName()
Description copied from class: Function
Get the name of the function. This method must be implemented in all subclasses.
Overrides:
getName in class Function
Following copied from class: com.icl.saxon.expr.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
Overrides:
getDataType in class Expression
Returns:
Value.STRING

simplify


public Expression simplify()
                    throws XPathException
Validate and simplify
Overrides:
simplify in class Expression
Following copied from class: com.icl.saxon.expr.Expression
Returns:
the simplified expression

evaluateAsString


public java.lang.String evaluateAsString(Context context)
                                  throws XPathException
Evaluate the expression in a string context
Overrides:
evaluateAsString in class Expression
Following copied from class: com.icl.saxon.expr.Expression
Parameters:
context - The context in which the expression is to be evaluated
Returns:
the value of the expression, evaluated in the current context

evaluate


public Value evaluate(Context c)
               throws XPathException
Evaluate in a general context
Overrides:
evaluate in class Expression
Following copied from class: com.icl.saxon.expr.Expression
Parameters:
context - The context in which the expression is to be evaluated
Returns:
the value of the expression, evaluated in the current context

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
Overrides:
getDependencies in class Expression

reduce


public Expression reduce(int dep,
                         Context c)
                  throws XPathException
Remove dependencies.
Overrides:
reduce in class Expression
Following copied from class: com.icl.saxon.expr.Expression
Parameters:
dependencies - The dependencies to be removed, e.g. Context.VARIABLES
context - The context to be used for the partial evaluation
Returns:
a new expression (or Value) that does not have any of the specified dependencies
