Constructor Details

Annotations

public Annotations(byte annotationType,
 int nameIndex,
 int length,
 AnnotationEntry[] annotationTable,
 ConstantPool constantPool,
 boolean isRuntimeVisible)

Constructs an instance.

Parameters:

annotationType - the subclass type of the annotation

nameIndex - Index pointing to the name Code

length - Content length in bytes

annotationTable - the actual annotations

constantPool - Array of constants

isRuntimeVisible - whether this Annotation visible at runtime

Method Details

accept

public void accept(Visitor v)

Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

Specified by:

accept in interface Node

Specified by:

accept in class Attribute

Parameters:

v - Visitor object

copy

public Attribute copy(ConstantPool constantPool)

Specified by:

copy in class Attribute

Parameters:

constantPool - constant pool to save.

Returns:

deep copy of this attribute.

getAnnotationEntries

public AnnotationEntry[] getAnnotationEntries()

Gets the array of annotation entries in this annotation

getNumAnnotations

public final int getNumAnnotations()

Gets the number of annotation entries in this annotation.

Returns:

the number of annotation entries in this annotation

isRuntimeVisible

public boolean isRuntimeVisible()

iterator

public Iterator<AnnotationEntry> iterator()

Specified by:

iterator in interface Iterable<AnnotationEntry>

setAnnotationTable

public final void setAnnotationTable(AnnotationEntry[] annotationTable)

Sets the entries to set in this annotation.

Parameters:

annotationTable - the entries to set in this annotation

toString

public final String toString()

Converts to a String representation.

Overrides:

toString in class Attribute

Returns:

String representation

writeAnnotations

protected void writeAnnotations(DataOutputStream dos)
                         throws IOException
