addStep

public void addStep(Step step)
Description copied from interface: LocationPath
Add the next step to this location path.

Specified by:
addStep in interface LocationPath

getSteps

public List getSteps()
Description copied from interface: LocationPath
Returns the ordered list of steps in this location path. This list may be live.

Specified by:
getSteps in interface LocationPath
Returns:
the ordered list of steps in this location path

simplify

public Expr simplify()
Description copied from interface: Expr
Simplifies the XPath expression. For example, the expression //para[1 = 1] could be simplified to //para. In practice, this is usually a noop. Jaxen does not currently perform any simplification.

Specified by:
simplify in interface Expr
Overrides:
simplify in class DefaultExpr
Returns:
the simplified expression

getText

public String getText()
Description copied from interface: Expr
Returns a String containing the XPath expression.

Specified by:
getText in interface Expr
Returns:
the text form of this XPath expression

isAbsolute

public boolean isAbsolute()
Description copied from interface: LocationPath
Returns true if this is an absolute location path; false if it isn't. Absolute location paths all begiune with / or //.

Specified by:
isAbsolute in interface LocationPath
Returns:
true if this is an absol;ute location path; false if it isn't

evaluate

public Object evaluate(Context context)
                throws JaxenException
Description copied from interface: Expr
Evaluate the expression in the given context, and return the result. The result will be a java.lang.Double for expressions that return a number, a java.lang.String for expressions that return a string, a java.lang.Boolean for expressions that return a boolean, and a java.util.List for expressions that return a node-set. In the latter case, the elements of the list are the actual objects from the source document model. Copies are not made.

Specified by:
evaluate in interface Expr
Parameters:
context - the context in which the expression is evaluated
Returns:
an object representing the result of the evaluation
Throws:
JaxenException
