isCompilable()
Check whether a node can be compiled to bytecode.
|
boolean |
isWritable(ExpressionState state)
Determine if this expression node will support a setValue() call.
|
void |
setValue(ExpressionState state,
Object value)
Evaluate the expression to a node and then set the new value on that node.
