Returns the type which was used when this variable expression was created. For example, getType() may return a boxed type while this method would return the primitive type.
Tells if this variable or the accessed variable is used in a closure context, like in the following example :
def str = 'Hello'
def cl = { println str }
The "str" variable is closure shared.
For internal use only. This flag is used by compiler internals and should probably be converted to a node metadata in future.
Use this method to tell if a variable is used in a closure, like in the following example:
def str = 'Hello'
def cl = { println str }
The "str" variable is closure shared. The variable expression inside the closure references an
accessed variable "str" which must have the closure shared flag set.
inClosure - tells if this variable is later referenced in a closureSet the type of this variable. If you call this method from an AST transformation and that the accessed variable is (shared, this operation is unsafe and may lead to a verify error at compile time. Instead, set the type of the accessed variable
cn - the type to be set on this variableFor internal use only. This flag is used by compiler internals and should probably be converted to a node metadata in future.
