Constructor Details

AnnotationDefault

public AnnotationDefault(int nameIndex,
 int length,
 ElementValue defaultValue,
 ConstantPool constantPool)

Constructs an AnnotationDefault attribute.

Parameters:

nameIndex - Index pointing to the name Code.

length - Content length in bytes.

defaultValue - The annotation's default value.

constantPool - Array of constants.

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. That is, the hierarchy of methods, fields, attributes, and other elements forms 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)

Description copied from class: Attribute

Creates a deep copy of this attribute.

Specified by:

copy in class Attribute

Parameters:

constantPool - constant pool to save.

Returns:

deep copy of this attribute.

dump

public final void dump(DataOutputStream dos)
                throws IOException

Description copied from class: Attribute

Dumps attribute to file stream in binary format.

Overrides:

dump in class Attribute

dos - Output file stream.

Throws:

IOException - Thrown if an I/O error occurs.

getDefaultValue

public final ElementValue getDefaultValue()

Gets the default value.

Returns:

The default value.

setDefaultValue

public final void setDefaultValue(ElementValue defaultValue)

Sets the default value of this methodinfo's annotation.

Parameters:

defaultValue - The default value of this methodinfo's annotation.
