Class Current

public class Current extends SystemFunction implements XSLTFunction

Implement the XSLT current() function

Method Summary
int	computeSpecialProperties() Get the static properties of this expression (other than its type).
Item	evaluateItem(XPathContext c) Evaluate in a general context
int	getIntrinsicDependencies() Determine the dependencies
Expression	preEvaluate(StaticContext env) preEvaluate: this method suppresses compile-time evaluation by doing nothing (because the value of the expression depends on the runtime context)

Get the static properties of this expression (other than its type). The result is bit-signficant. These properties are used for optimizations. In general, if property bit is set, it is true, but if it is unset, the value is unknown.

evaluateItem

public Item evaluateItem(XPathContext c)

Evaluate in a general context

getIntrinsicDependencies

public int getIntrinsicDependencies()

Determine the dependencies

preEvaluate

public Expression preEvaluate(StaticContext env)

preEvaluate: this method suppresses compile-time evaluation by doing nothing (because the value of the expression depends on the runtime context)
