Constructor Detail

FieldVisitor

protected FieldVisitor(int api)

Constructs a new FieldVisitor.

api - the ASM API version implemented by this visitor. Must be one of the ASMx values in Opcodes.

FieldVisitor

protected FieldVisitor(int api,
                       FieldVisitor fieldVisitor)

Constructs a new FieldVisitor.

Parameters:

api - the ASM API version implemented by this visitor. Must be one of the ASMx values in Opcodes.

fieldVisitor - the field visitor to which this visitor must delegate method calls. May be null.

Method Detail

getDelegate

public FieldVisitor getDelegate()

The field visitor to which this visitor must delegate method calls. May be null.

Returns:

the field visitor to which this visitor must delegate method calls, or null.

visitAnnotation

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

Visits an annotation of the field.

Parameters:

descriptor - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

Returns:

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 descriptor,
                                             boolean visible)

Visits an annotation on the type of the field.

Parameters:

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

descriptor - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

Returns:

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

visitAttribute

public void visitAttribute(Attribute attribute)

Visits a non standard attribute of the field.
