Method Detail

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)

getOperator

public abstract java.lang.String getOperator()

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

getText

public java.lang.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

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

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
