Variable |
getAccessedVariable() |
Expression |
getInitialExpression()
expression used to initialize the variable or null of there
is no initialization.
|
int |
getModifiers() |
String |
getName()
the name of the variable
|
ClassNode |
getOriginType()
Returns the type which was used when this variable expression was created.
|
String |
getText() |
ClassNode |
getType()
the type of the variable
|
boolean |
hasInitialExpression()
returns true if there is an initialization expression
|
boolean |
isClosureSharedVariable()
Tells if this variable or the accessed variable is used in a closure context, like in the following
example :
|
boolean |
isDynamicTyped() |
boolean |
isInStaticContext()
returns true if this variable is used in a static context.
|
boolean |
isSuperExpression() |
boolean |
isThisExpression() |
boolean |
isUseReferenceDirectly()
For internal use only.
|
void |
setAccessedVariable(Variable origin) |
void |
setClosureSharedVariable(boolean inClosure)
Use this method to tell if a variable is used in a closure, like in the following example:
|
void |
setInStaticContext(boolean inStaticContext) |
void |
setModifiers(int modifiers) |
void |
setType(ClassNode cn)
Set the type of this variable.
|
void |
setUseReferenceDirectly(boolean useRef)
For internal use only.
|
String |
toString() |
Expression |
transformExpression(ExpressionTransformer transformer)
Return a copy of the expression calling the transformer on any nested expressions

this operation is unsafe and may lead to a verify error at compile time. Instead, set the type of
the accessed variable

public boolean isClosureSharedVariable()
def str = 'Hello' def cl = { println str }The "str" variable is closure shared.
isClosureSharedVariable
in interface Variable
public void setClosureSharedVariable(boolean inClosure)
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.
