All Known Implementing Classes:

StdAttributeList

public interface AttributeList

Interface for lists of attributes.

Method Summary

Modifier and Type	Method	Description
int	byteLength()	Get the total length of this list in bytes, when part of a class file.
Attribute	findFirst(String name)	Get the first attribute in the list with the given name, if any.
Attribute	findNext(Attribute attrib)	Get the next attribute in the list after the given one, with the same name, if any.
Attribute	get(int n)	Get the nth attribute.
boolean	isMutable()	Get whether this instance is mutable.
int	size()	Get the number of attributes in the list.

Method Details

isMutable

boolean isMutable()

Get whether this instance is mutable. Note that the AttributeList interface itself doesn't provide any means of mutation, but that doesn't mean that there isn't a non-interface way of mutating an instance.

Returns:

true iff this instance is somehow mutable

size

int size()

Get the number of attributes in the list.

Returns:

the size

get

Attribute get(int n)

Get the nth attribute.

Parameters:

n - n >= 0, n < size(); which attribute

Returns:

non-null; the attribute in question

byteLength

int byteLength()

Get the total length of this list in bytes, when part of a class file. The returned value includes the two bytes for the attributes_count length indicator.

Returns:

>= 2; the total length, in bytes

findFirst

Attribute findFirst(String name)

Get the first attribute in the list with the given name, if any.

Parameters:

name - non-null; attribute name

Returns:

null-ok; first attribute in the list with the given name, or null if there is none

findNext

Attribute findNext(Attribute attrib)

Get the next attribute in the list after the given one, with the same name, if any.

Parameters:

attrib - non-null; attribute to start looking after

Returns:

null-ok; next attribute after attrib with the same name as attrib
