private	Visitor(java.util.Set<java.lang.Class<?>> classes, boolean verbose)	Creates a new ServiceLocatorTestRule.Visitor.

Method Summary

Modifier and Type	Method	Description
void	visit(int version, int access, java.lang.String name, java.lang.String signature, java.lang.String superName, java.lang.String[] interfaces)	Called when a class file is encountered and internally records its fully qualified class name.
org.objectweb.asm.AnnotationVisitor	visitAnnotation(java.lang.String annotationClassDescriptor, boolean visible)	If the supplied annotationClassDescriptor is equal to "Lorg/jvnet/hk2/annotations/Service;", and if the supplied visible parameter is true, attempts to load the Class encountered in the prior (guaranteed) call to the visit(int, int, String, String, String, String[]) method, and, if that is successful, adds the resulting Class to the {@linkplain ServiceLocatorTestRule.Visitor#ServiceLocatorTestRule.Visitor(Set, boolean) Set of Classes that was supplied at construction time}.
void	visitEnd()	Does nothing when invoked.

Field Detail

className

private java.lang.String className

The fully qualified class name of the Class being visited.

This field may be null.

This field is set by the visit(int, int, String, String, String, String[]) method.

visit(int, int, String, String, String, String[])

classes

private final java.util.Set<java.lang.Class<?>> classes

A Set of Classes that will be added to by the visitAnnotation(String, boolean) method.

This field is never null.

visitAnnotation(String, boolean)

Constructor Detail

Visitor

private Visitor(java.util.Set<java.lang.Class<?>> classes,
                boolean verbose)

Creates a new ServiceLocatorTestRule.Visitor.

Parameters:

classes - A Set of Classes that will be added to by the visitAnnotation(String, boolean) method; must not be null; must be mutable

verbose - whether or not additional information should be output

See Also:

visitAnnotation(String, boolean)

Method Detail

visit

public final void visit(int version,
                        int access,
                        java.lang.String name,
                        java.lang.String signature,
                        java.lang.String superName,
                        java.lang.String[] interfaces)

Called when a class file is encountered and internally records its fully qualified class name.

It is guaranteed that this method will be called before the visitAnnotation(String, boolean) method on the current thread.

Overrides:

visit in class ClassVisitorImpl

Parameters:

version - ignored

access - ignored

name - the name of the class, whose package segments are separated with slashes ("/"); may be null

signature - ignored

superName - ignored

interfaces - ignored

See Also:

visitAnnotation(String, boolean)

visitAnnotation

public final org.objectweb.asm.AnnotationVisitor visitAnnotation(java.lang.String annotationClassDescriptor,
                                                                 boolean visible)

If the supplied annotationClassDescriptor is equal to "Lorg/jvnet/hk2/annotations/Service;", and if the supplied visible parameter is true, attempts to load the Class encountered in the prior (guaranteed) call to the visit(int, int, String, String, String, String[]) method, and, if that is successful, adds the resulting Class to the {@linkplain ServiceLocatorTestRule.Visitor#ServiceLocatorTestRule.Visitor(Set, boolean) Set of Classes that was supplied at construction time}.

Overrides:

visitAnnotation in class ClassVisitorImpl

Parameters:

annotationClassDescriptor - the descriptor for the annotation being visited; may be null

visible - whether the annotation is visible or not

Returns:

null when invoked

visitEnd

public final void visitEnd()

Does nothing when invoked.

Overrides:
