org.codehaus.groovy.ast.CodeVisitorSupport

org.codehaus.groovy.ast.ClassCodeVisitorSupport

asteroid.transformer.AbstractTransformer

asteroid.transformer.AbstractExpressionTransformer<T>

Type Parameters:

T - use as a hint for the transformExpression(T) method parameter

All Implemented Interfaces:

Transformer, ExpressionTransformer, GroovyClassVisitor, GroovyCodeVisitor, ErrorCollecting

public abstract class AbstractExpressionTransformer<T extends Expression>
extends AbstractTransformer

This Transformer could be used as a base for transforming Expression instances.

IMPORTANT: The parameter type is only used as a hint. If you are not carefull on how you define the search criteria you could get a ClassCastException at runtime. The criteria should ask for the type of the expression in the first place.

Since:

0.2.0

AbstractExpressionTransformer

public AbstractExpressionTransformer(Class<T> clazz,
                                     SourceUnit sourceUnit,
                                     Closure<Boolean> criteria)

Every instance needs the source unit awareness and the name of the method it's going to transform

Parameters:

clazz - the type of the expression we're interested in

sourceUnit - Needed to apply scope

criteria - the criteria used to search the interesting Expression

Method Detail

transform

public Expression transform(Expression expression)

Specified by:

transform in interface ExpressionTransformer

Overrides:

transform in class ClassCodeExpressionTransformer

transformExpression

public abstract Expression transformExpression(T expression)

This method will transform the expression into its final version.

Parameters:

expression - the method expression you want to transform

Returns:

the final version of the method expression

Since:

everything

@Deprecated
public static Closure<Boolean> everything()

Deprecated.

use Criterias

This criteria will make the transformer to process every Expression

Returns:

a criteria to process everything
