public RuntimeAnnotationsAttr(String name,
 AnnotationEntry[] entries,
 int numEntries,
 AttrContainer container)

Add a new AnnotationAttr to a Member.

Method Details

getAnnotationsAttr

public static RuntimeAnnotationsAttr getAnnotationsAttr(AttrContainer container,
 String name)

getRuntimeVisibleAnnotations

public static RuntimeAnnotationsAttr getRuntimeVisibleAnnotations(AttrContainer container)

Get or create a RuntimeVisibleAnnotations attribute.

getRuntimeInvisibleAnnotations

public static RuntimeAnnotationsAttr getRuntimeInvisibleAnnotations(AttrContainer container)

Get or create a RuntimeInvisibleAnnotations attribute.

getAnnotation

public <T extends Annotation> T getAnnotation(Class<T> clas)

getAnnotation

public static <T extends Annotation> T getAnnotation(AttrContainer container,
 Class<T> clas)

maybeAddAnnotation

public static void maybeAddAnnotation(AttrContainer container,
 AnnotationEntry annotation)

Add to appropriate annotations attribute. If the annotation's retention policy is RUNTIME, add to the RuntimeVisibleAnnotations attribute. If the annotation's retention policy is CLASS, add to the RuntimeInvisibleAnnotations attribute. Otherwise, ignore the annotation.

addAnnotation

public void addAnnotation(AnnotationEntry ann)

Add an annotation to this attribute.

public int getLength()

Return the length of the attribute in bytes. Does not include the 6-byte header (for the name_index and the length).

Specified by:

print

public void print(ClassTypeWriter dst)

Overrides:

print in class Attribute

assignConstants

public void assignConstants(ClassType cl)

Description copied from class: Attribute

Add any needed constant pool entries for this Attribute. Overridden by sub-classes. Do any other cleanup needed before writing out a .class file.
