ASTAndNode

public ASTAndNode(int id)

参数:

id -

public ASTAndNode(Parser p,
                  int id)

参数:

p -

id -

方法详细资料

jjtAccept

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

指定者:

jjtAccept 在接口中 Node

覆盖:

jjtAccept 在类中 SimpleNode

返回:

The Node execution result object.

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

指定者:

value 在接口中 Node

覆盖:

value 在类中 SimpleNode

参数:

context -

返回:

The value of the expression.

抛出:

MethodInvocationException

另请参阅:

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

evaluate

public boolean evaluate(InternalContextAdapter context)
                 throws MethodInvocationException

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

指定者:

evaluate 在接口中 Node

覆盖:

evaluate 在类中 SimpleNode

参数:

context -

返回:

True if both sides are true.

抛出:

MethodInvocationException
