CtVisitor

public abstract class Query
extends CtScanner

This class provides some useful methods to retrieve program elements and reference through a CtScanner-based deep search. It uses the Filter and ReferenceFilter facitily to select the right elements or references.

Method Summary

static <E extends CtElement> java.util.List<E>	getElements(CtElement rootElement, Filter<E> filter) Returns all the program elements that match the filter.
static <E extends CtElement> java.util.List<E>	getElements(Factory factory, Filter<E> filter) Within a given factory, returns all the program elements that match the filter.
static <T extends CtReference> java.util.List<T>	getReferences(CtElement rootElement, ReferenceFilter<T> filter) Returns all the program element references that match the filter.
static <R extends CtReference> java.util.List<R>	getReferences(Factory factory, ReferenceFilter<R> filter) Within a given factory, returns all the program element references that match the filter.

Method Detail

getElements

public static <E extends CtElement> java.util.List<E> getElements(Factory factory,
                                                                  Filter<E> filter)

Within a given factory, returns all the program elements that match the filter.

Type Parameters:

E - the type of the seeked program elements

Parameters:

factory - the factory that contains the elements where to recursive search on

filter - the filter which defines the matching criteria

getElements

public static <E extends CtElement> java.util.List<E> getElements(CtElement rootElement,
                                                                  Filter<E> filter)

Returns all the program elements that match the filter.

Type Parameters:

E - the type of the seeked program elements

Parameters:

rootElement - the element to start the recursive search on

filter - the filter which defines the matching criteria

getReferences

public static <T extends CtReference> java.util.List<T> getReferences(CtElement rootElement,
                                                                      ReferenceFilter<T> filter)

Returns all the program element references that match the filter.

Type Parameters:

T - the type of the seeked program element references

Parameters:

rootElement - the element to start the recursive search on

filter - the filter which defines the matching criteria

getReferences

public static <R extends CtReference> java.util.List<R> getReferences(Factory factory,
                                                                      ReferenceFilter<R> filter)

Within a given factory, returns all the program element references that match the filter.

Type Parameters:

R - the type of the seeked program element references

Parameters:

factory - the factory that contains the references where to recursive search on

filter - the filter which defines the matching criteria
