类 ASTIndex

java.lang.Object

bboss.org.apache.velocity.runtime.parser.node.SimpleNode

bboss.org.apache.velocity.runtime.parser.node.ASTIndex

所有已实现的接口:

Node, Renderable

public class ASTIndex
extends SimpleNode

This node is responsible for the bracket notation at the end of a reference, e.g., $foo[1]

方法详细资料

init

public java.lang.Object init(InternalContextAdapter context,
                             java.lang.Object data)
                      throws TemplateInitException

指定者:

init 在接口中 Node

覆盖:

init 在类中 SimpleNode

返回:

The init result.

抛出:

TemplateInitException

Node.init(bboss.org.apache.velocity.context.InternalContextAdapter, java.lang.Object)

adjMinusIndexArg

public static java.lang.Object adjMinusIndexArg(java.lang.Object argument,
                                                java.lang.Object o,
                                                InternalContextAdapter context,
                                                SimpleNode node)

If argument is an Integer and negative, then return (o.size() - argument). Otherwise return the original argument. We use this to calculate the true index of a negative index e.g., $foo[-1]. If no size() method is found on the 'o' object, then we throw an VelocityException.

参数:

context - Used to access the method cache.

node - ASTNode used for error reporting.

execute

public java.lang.Object execute(java.lang.Object o,
                                InternalContextAdapter context)
                         throws MethodInvocationException

指定者:

execute 在接口中 Node

覆盖:

execute 在类中 SimpleNode

返回:

The execution result.

抛出:

MethodInvocationException
