            return new FieldVisitor(ASM5, fv) {

                @Override
                public AnnotationVisitor visitAnnotation(String desc, boolean visible) {
                    AnnotationVisitor av = super.visitAnnotation(desc, visible);
                    if (S.eq(CONF_DESC, desc)) {
                        return new AnnotationVisitor(ASM5, av) {

                            @Override
                            public void visit(String name, Object value) {
                                staticConfigurationFields.put(fieldName, S.string(value));
                                super.visit(name, value);
                            }

            };
        }
    };
}

Example 2 with FieldVisitor

use of act.asm.FieldVisitor in project act-ebean by actframework.

    FieldVisitor fv = super.visitField(access, name, desc, signature, value);
    if (null == createdAt && null == lastModifiedAt) {
        return fv;
    }
    final boolean isCreatedAt = name.equals(createdAt);
    final boolean isLastModified = !isCreatedAt && name.equals(lastModifiedAt);
    if (!isCreatedAt && !isLastModified) {
        return fv;
    }
    return new FieldVisitor(ASM5, fv) {

        @Override
        public void visitEnd() {
            AnnotationVisitor av;
            if (isCreatedAt) {
                av = fv.visitAnnotation("Lcom/avaje/ebean/annotation/WhenCreated;", true);
            } else {
                av = fv.visitAnnotation("Lcom/avaje/ebean/annotation/WhenModified;", true);
            }
            av.visitEnd();
            super.visitEnd();
