Constructor Detail

### ASTOrNode

    public ASTOrNode(int id)

Parameters:
  `id` -

### ASTOrNode

    public ASTOrNode(Parser p,
                     int id)

Parameters:
  `p` -
  `id` -

Method Detail

### jjtAccept

    public Object jjtAccept(ParserVisitor visitor,
                            Object data)

  Specified by:
    `jjtAccept` in interface `Node`
  Overrides:
    `jjtAccept` in class `SimpleNode`
  See Also:
    `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 Expression value.
  Throws:
    `MethodInvocationException`
  See Also:
    `Node.value(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`
  See Also:
    `Node.evaluate(org.apache.velocity.context.InternalContextAdapter)`
