Deprecated.

Method Detail

getOperator

public String getOperator()

Deprecated.

Description copied from interface: BinaryExpr

Returns the operator for the binary expression such as "+" or "div".

Specified by:

getOperator in interface BinaryExpr

Returns:

the operator for the expression

toString

public String toString()

Deprecated.

evaluate

public Object evaluate(Context context)
                throws JaxenException

Deprecated.

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

getLHS

public Expr getLHS()

Description copied from interface: BinaryExpr

Returns the left-hand side of the binary expression.

Specified by:

getLHS in interface BinaryExpr

Returns:

the left hand side expression

getRHS

public Expr getRHS()

Description copied from interface: BinaryExpr

Returns the right-hand side of the binary expression.

Specified by:

getRHS in interface BinaryExpr

Returns:

the right-hand side expression

setLHS

public void setLHS(Expr lhs)

setRHS

public void setRHS(Expr rhs)

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

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
