Constructor Detail

FieldWriter

FieldWriter(ClassWriter cw,
            int access,
            java.lang.String name,
            java.lang.String desc,
            java.lang.String signature,
            java.lang.Object value)

Constructs a new FieldWriter.

Parameters:

cw - the class writer to which this field must be added.

access - the field's access flags (see Opcodes).

name - the field's name.

desc - the field's descriptor (see Type).

signature - the field's signature. May be null.

value - the field's constant value. May be null.

Method Detail

visitAnnotation

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

Description copied from class: FieldVisitor

Visits an annotation of the field.

Overrides:

visitAnnotation in class FieldVisitor

Parameters:

desc - 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 desc,
                                             boolean visible)

Description copied from class: FieldVisitor

Visits an annotation on the type of the field.

Overrides:

visitTypeAnnotation in class FieldVisitor

Parameters:

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.

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 attr)

Description copied from class: FieldVisitor

Visits a non standard attribute of the field.

Overrides:

visitAttribute in class FieldVisitor

Parameters:

attr - an attribute.

visitEnd

public void visitEnd()

Description copied from class: FieldVisitor

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.

Overrides:

visitEnd in class FieldVisitor

getSize

int getSize()

Returns the size of this field.

Returns:

the size of this field.

put

void put(ByteVector out)

Puts the content of this field into the given byte vector.

Parameters:

out - where the content of this field must be put.
