public class StaticCompilationTransformer
extends ClassCodeExpressionTransformer

Some expressions use symbols as aliases to method calls (<<, +=, ...). In static compilation, if such a method call is found, we transform the original binary expression into a method call expression so that the call gets statically compiled.

transform

public Expression transform(Expression expr)

Description copied from class: ClassCodeExpressionTransformer

NOTE: This method does not visit Expressions within Closures, for performance and historical reasons. If you want those Expressions to be visited, you can do this:

 
 public class YourTransformer extends ClassCodeExpressionTransformer {
   ...

   @Override
   public Expression transform(final Expression expr) {
     if (expr instanceof ClosureExpression) {
       expr.visit(this);

       return expr;
     }
     // ...
   }
 }
 

Specified by:

transform in interface ExpressionTransformer

Overrides:

transform in class ClassCodeExpressionTransformer

visitClass

public void visitClass(ClassNode node)

Description copied from interface: GroovyClassVisitor

Visit a ClassNode.

Specified by:

visitClass in interface GroovyClassVisitor

Overrides:

visitClass in class ClassCodeVisitorSupport

visitConstructorOrMethod

protected void visitConstructorOrMethod(MethodNode node,
 boolean isConstructor)

Overrides:

visitConstructorOrMethod in class ClassCodeExpressionTransformer
