类 ASTDirective

java.lang.Object

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

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

所有已实现的接口:

Node, Renderable

public class ASTDirective
extends SimpleNode

This class is responsible for handling the pluggable directives in VTL. For example : #foreach() Please look at the Parser.jjt file which is what controls the generation of this class.

SimpleNode.render(bboss.org.apache.velocity.context.InternalContextAdapter, java.io.Writer)

setDirectiveName

public void setDirectiveName(java.lang.String str)

Sets the directive name. Used by the parser. This keeps us from having to dig it out of the token stream and gives the parse the change to override.

参数:

str -

getDirectiveName

public java.lang.String getDirectiveName()

Gets the name of this directive.

返回:

The name of this directive.

toString

public java.lang.String toString()

覆盖:

toString 在类中 SimpleNode
