- org.codehaus.groovy.ast.CodeVisitorSupport
- - org.codehaus.groovy.ast.ClassCodeVisitorSupport
  - - org.codehaus.groovy.ast.ClassCodeExpressionTransformer
    - - asteroid.transformer.AbstractTransformer

All Implemented Interfaces:

Transformer, ExpressionTransformer, GroovyClassVisitor, GroovyCodeVisitor, ErrorCollecting

Direct Known Subclasses:

AbstractClassNodeTransformer, AbstractExpressionTransformer, AbstractMethodNodeTransformer, AbstractStatementTransformer
```
public abstract class AbstractTransformer
extends ClassCodeExpressionTransformer
implements Transformer
```
Most transformers need at some point the source unit in order to fix or apply properly the scope to each variable. This class enforces the use of a SourceUnit instance for every transformer

Since:

0.2.0
