Method Detail

box

public ClassNode box()

castToBool

public void castToBool(int mark, boolean emptyDefault)
ensure last marked parameter on the stack is a primitive boolean if mark==stack size, we assume an empty expression or statement. was used and we will use the value given in emptyDefault as boolean if mark==stack.size()-1 the top element will be cast to boolean using Groovy truth. In other cases we throw a GroovyBugError
