ASTElseIfStatement

public ASTElseIfStatement(int id)

ASTElseIfStatement

public ASTElseIfStatement(Parser p,
                          int id)
Method Detail

jjtAccept

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

Specified by:
jjtAccept in interface Node
Overrides:
jjtAccept in class SimpleNode

evaluate

public boolean evaluate(InternalContextAdapter context)
                 throws MethodInvocationException
An ASTElseStatement is true if the expression it contains evaluates to true. Expressions know how to evaluate themselves, so we do that here and return the value back to ASTIfStatement where this node was originally asked to evaluate itself.

Specified by:
evaluate in interface Node
Overrides:
evaluate in class SimpleNode
MethodInvocationException

render

public boolean render(InternalContextAdapter context,
                      java.io.Writer writer)
               throws java.io.IOException,
                      MethodInvocationException,
                      ResourceNotFoundException,
                      ParseErrorException
renders the block

Specified by:
render in interface Node
Overrides:
render in class SimpleNode
java.io.IOException
MethodInvocationException
ResourceNotFoundException
