Foreach

public Foreach()

方法详细资料

getName

public java.lang.String getName()

Return name of this directive.

指定者:

getName 在类中 Directive

返回:

The name of this directive.

getType

public int getType()

Return type of this directive.

指定者:

getType 在类中 Directive

返回:

The type of this directive.

init

public void init(RuntimeServices rs,
                 InternalContextAdapter context,
                 Node node)
          throws TemplateInitException

simple init - init the tree and get the elementKey from the AST

覆盖:

init 在类中 Directive

参数:

rs -

context -

node -

抛出:

TemplateInitException

put

protected void put(InternalContextAdapter context,
                   java.lang.String key,
                   java.lang.Object value)

Extension hook to allow subclasses to control whether loop vars are set locally or not. So, those in favor of VELOCITY-285, can make that happen easily by overriding this and having it use context.localPut(k,v). See VELOCITY-630 for more on this.

render

public boolean render(InternalContextAdapter context,
                      java.io.Writer writer,
                      Node node)
               throws java.io.IOException,
                      MethodInvocationException,
                      ResourceNotFoundException,
                      ParseErrorException

renders the #foreach() block

指定者:

render 在类中 Directive

参数:

context -

writer -

node -

返回:

True if the directive rendered successfully.

抛出:

java.io.IOException

MethodInvocationException

ResourceNotFoundException

ParseErrorException

clean

protected void clean(InternalContextAdapter context,
                     java.lang.Object o,
                     java.lang.Object savedCounter,
                     java.lang.Object nextFlag)
