jjtAccept

public java.lang.Object jjtAccept(ParserVisitor visitor,
                                  java.lang.Object data)

Specified by:

jjtAccept in interface Node

Overrides:

jjtAccept in class SimpleNode

Returns:

The Node execution result object.

value

public java.lang.Object value(InternalContextAdapter context)
                       throws MethodInvocationException

Returns the value of the expression. Since the value of the expression is simply the boolean result of evaluate(), lets return that.

Specified by:

value in interface Node

Overrides:

value in class SimpleNode

Parameters:

context -

Returns:

The Expression value.

Throws:

MethodInvocationException

Node.value(bboss.org.apache.velocity.context.InternalContextAdapter)

evaluate

public boolean evaluate(InternalContextAdapter context)
                 throws MethodInvocationException

the logical or : the rule : left || null -> left null || right -> right null || null -> false left || right -> left || right

Specified by:

evaluate in interface Node

Overrides:

evaluate in class SimpleNode

Parameters:

context -

Returns:

The evaluation result.

Throws:

MethodInvocationException
