visitAnnotation

public AnnotationVisitor visitAnnotation(java.lang.String desc,
                                         boolean visible)

Visits an annotation of the field.

参数:

desc - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

返回:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitTypeAnnotation

public AnnotationVisitor visitTypeAnnotation(int typeRef,
                                             TypePath typePath,
                                             java.lang.String desc,
                                             boolean visible)

Visits an annotation on the type of the field.

参数:

typeRef - a reference to the annotated type. The sort of this type reference must be FIELD. See TypeReference.

typePath - the path to the annotated type argument, wildcard bound, array element type, or static inner type within 'typeRef'. May be null if the annotation targets 'typeRef' as a whole.

desc - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

返回:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitAttribute

public void visitAttribute(Attribute attr)

Visits a non standard attribute of the field.

参数:

attr - an attribute.

visitEnd

public void visitEnd()

Visits the end of the field. This method, which is the last one to be called, is used to inform the visitor that all the annotations and attributes of the field have been visited.
