Method Detail
public Variable getAccessedVariable()
public Expression getInitialExpression()
public int getModifiers()
public String getName()
public ClassNode getOriginType()
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.
- Returns:
- the type which was used to define this variable expression
public String getText()
public ClassNode getType()
public boolean hasInitialExpression()
public boolean isClosureSharedVariable()
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.
- Returns:
- true if this variable is used in a closure
public boolean isDynamicTyped()
public boolean isInStaticContext()
public boolean isSuperExpression()
public boolean isThisExpression()
public boolean isUseReferenceDirectly()
For internal use only. This flag is used by compiler internals and should probably be converted to a node metadata in future.
public void setAccessedVariable(Variable origin)
public void setClosureSharedVariable(boolean inClosure)
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.
- Parameters:
-
inClosure
- tells if this variable is later referenced in a closure
public void setInStaticContext(boolean inStaticContext)
public void setModifiers(int modifiers)
public void setType(ClassNode cn)
Set 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
- Parameters:
-
cn
- the type to be set on this variable
public void setUseReferenceDirectly(boolean useRef)
For internal use only. This flag is used by compiler internals and should probably be converted to a node metadata in future.
- Parameters:
- useRef
public String toString()
public Expression transformExpression(ExpressionTransformer transformer)
public void visit(GroovyCodeVisitor visitor)
