Method Detail

jjtAccept

public Object jjtAccept(ParserVisitor visitor,
               Object data)

Specified by:

jjtAccept in interface Node

Overrides:

jjtAccept in class SimpleNode

Returns:

The Node execution result object.

SimpleNode.jjtAccept(org.apache.velocity.runtime.parser.node.ParserVisitor, java.lang.Object)

value

public 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 value of the expression.

Throws:

MethodInvocationException

See Also:

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

public boolean evaluate(InternalContextAdapter context)
                 throws MethodInvocationException

logical and : null && right = false left && null = false null && null = false

Specified by:

evaluate in interface Node

Overrides:

evaluate in class SimpleNode

Parameters:

context -

Returns:
