Description copied from class:ExpressionReturn a copy of the expression calling the transformer on any nested expressions- Specified by:
transformExpressionin classExpression
-
toString
public java.lang.String toString()- Overrides:
toStringin classjava.lang.Object
-
getCode
This gets the code statement of the closure. You can read this method to find out what actions the closure is going to perform.- Returns:
- the code statement of the closure
-
setCode
This sets the code statement of the closure. You can use this method in order to add more actions during the closure execution.- Parameters:
code- the new Statement
-
getParameters
- Returns:
- an array of zero (for implicit it) or more (when explicit args given) parameters or null otherwise (representing explicit no args)
-
isParameterSpecified
public boolean isParameterSpecified()- Returns:
trueif one or more explicit parameters are supplied
-
getVariableScope
-
setVariableScope
-
getText
