transformExpressionDescription copied from class:ExpressionReturn a copy of the expression calling the transformer on any nested expressions- Specified by:
- transformExpressionin class- Expression
 
- 
getText
- 
getNameDescription copied from interface:Variablethe name of the variable
- 
toString
- 
getInitialExpressionDescription copied from interface:Variableexpression used to initialize the variable or null of there is no initialization.- Specified by:
- getInitialExpressionin interface- Variable
 
- 
hasInitialExpressionpublic boolean hasInitialExpression()Description copied from interface:Variablereturns true if there is an initialization expression- Specified by:
- hasInitialExpressionin interface- Variable
 
- 
isInStaticContextpublic boolean isInStaticContext()Description copied from interface:Variablereturns true if this variable is used in a static context. A static context is any static initializer block, when this variable is declared as static or when this variable is used in a static method- Specified by:
- isInStaticContextin interface- Variable
 
- 
setInStaticContextpublic void setInStaticContext(boolean inStaticContext) 
- 
setTypeSet the type of this variable. If you call this method from an AST transformation and that theaccessed variableis (shared, this operation is unsafe and may lead to a verify error at compile time. Instead, set the type of theaccessed variable- Overrides:
- setTypein class- Expression
- Parameters:
- cn- the type to be set on this variable
 
- 
isDynamicTypedpublic boolean isDynamicTyped()- Specified by:
- isDynamicTypedin interface- Variable
 
- 
getModifierspublic int getModifiers()- Specified by:
- getModifiersin interface- Variable
 
- 
setUseReferenceDirectlypublic 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 the future.- Parameters:
- useRef-
 
- 
isUseReferenceDirectlypublic boolean isUseReferenceDirectly()For internal use only. This flag is used by compiler internals and should probably be converted to a node metadata in the future.
- 
getTypeDescription copied from interface:Variablethe type of the variable- Specified by:
- getTypein interface- Variable
- Overrides:
- getTypein class- Expression
 
- 
getOriginTypeReturns 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.- Specified by:
- getOriginTypein interface- Variable
- Returns:
- the type which was used to define this variable expression
 
- 
isThisExpressionpublic boolean isThisExpression()

isSuperExpressionpublic boolean isSuperExpression()
