transformExpression
Description copied from class:Expression
Transforms this expression and any nested expressions.- Specified by:
transformExpression
in classExpression
-
getText
-
getName
Description copied from interface:Variable
Returns the name of the variable. -
toString
-
getInitialExpression
Description copied from interface:Variable
Returns the expression used to initialize the variable or null of there is no initialization.- Specified by:
getInitialExpression
in interfaceVariable
-
hasInitialExpression
public boolean hasInitialExpression()Description copied from interface:Variable
Returns true if there is an initialization expression.- Specified by:
hasInitialExpression
in interfaceVariable
-
isInStaticContext
public boolean isInStaticContext()Description copied from interface:Variable
Returns 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:
isInStaticContext
in interfaceVariable
-
setInStaticContext
public void setInStaticContext(boolean inStaticContext) -
setType
Set the type of this variable. If you call this method from an AST transformation and that theaccessed variable
is (shared
, this operation is unsafe and may lead to a verify error at compile time. Instead, set the type of theaccessed variable
- Overrides:
setType
in classExpression
- Parameters:
cn
- the type to be set on this variable
-
isDynamicTyped
public boolean isDynamicTyped()- Specified by:
isDynamicTyped
in interfaceVariable
-
getModifiers
public int getModifiers()- Specified by:
getModifiers
in interfaceVariable
-
setUseReferenceDirectly
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 the future.- Parameters:
useRef
-
-
isUseReferenceDirectly
public 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. -
getType
Description copied from interface:Variable
Returns the type of the variable.- Specified by:
getType
in interfaceVariable
- Overrides:
getType
in classExpression
-
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.- Specified by:
getOriginType
in interfaceVariable
- Returns:
- the type which was used to define this variable expression
-
isThisExpression
public boolean isThisExpression() -
isSuperExpression
public boolean isSuperExpression() -
setModifiers
public void setModifiers(int modifiers)
