Interface ByteArray

All Superinterfaces:

IoAbsoluteReader, IoAbsoluteWriter

All Known Implementing Classes:

AbstractByteArray, BufferByteArray, ByteArrayPool.DirectBufferByteArray, CompositeByteArray

public interface ByteArray
extends IoAbsoluteReader, IoAbsoluteWriter

Represents a sequence of bytes that can be read or written directly or through a cursor.

Modifier and Type	Interface and Description
static interface	ByteArray.Cursor Provides relocatable, relative access to the underlying array.

Method Summary

Modifier and Type	Method and Description
ByteArray.Cursor	cursor() Get a cursor starting at index 0 (which may not be the start of the array).
ByteArray.Cursor	cursor(int index) Get a cursor starting at the given index.
boolean	equals(java.lang.Object other) A ByteArray is equal to another ByteArray if they start and end at the same index, have the same byte order, and contain the same bytes at each index.
int	first() Get the index of the first byte that can be accessed.
void	free() Remove any resources associated with this object.
byte	get(int index) Gets a byte from the given index.
void	get(int index, IoBuffer bb) Gets enough bytes to fill the IoBuffer from the given index.
int	getInt(int index) Gets an int from the given index.
java.lang.Iterable<IoBuffer>	getIoBuffers() Get the sequence of IoBuffers that back this array.
IoBuffer	getSingleIoBuffer() Gets a single IoBuffer that backs this array.
int	last() Gets the index after the last byte that can be accessed.
java.nio.ByteOrder	order() Gets the order of the bytes.
void	order(java.nio.ByteOrder order) Set the byte order of the array.

Method Detail

first

int first()

Description copied from interface: IoAbsoluteReader

Get the index of the first byte that can be accessed.

Specified by:

first in interface IoAbsoluteReader

Specified by:

first in interface IoAbsoluteWriter

last

int last()

Description copied from interface: IoAbsoluteReader

Gets the index after the last byte that can be accessed.

Specified by:

last in interface IoAbsoluteReader

Specified by:

last in interface IoAbsoluteWriter

order

java.nio.ByteOrder order()

Description copied from interface: IoAbsoluteReader

Gets the order of the bytes.

Specified by:

order in interface IoAbsoluteReader

Specified by:

order in interface IoAbsoluteWriter

order

void order(java.nio.ByteOrder order)

Set the byte order of the array.

free

void free()

Remove any resources associated with this object. Using the object after this method is called may result in undefined behaviour.

getIoBuffers

java.lang.Iterable<IoBuffer> getIoBuffers()

Get the sequence of IoBuffers that back this array. Compared to getSingleIoBuffer(), this method should be relatively efficient for all implementations.

getSingleIoBuffer

IoBuffer getSingleIoBuffer()

Gets a single IoBuffer that backs this array. Some implementations may initially have data split across multiple buffers, so calling this method may require a new buffer to be allocated and populated.

equals

boolean equals(java.lang.Object other)

A ByteArray is equal to another ByteArray if they start and end at the same index, have the same byte order, and contain the same bytes at each index.

Overrides:

equals in class java.lang.Object

get

byte get(int index)

Description copied from interface: IoAbsoluteReader

Gets a byte from the given index.

Specified by:

get in interface IoAbsoluteReader

get

void get(int index,
         IoBuffer bb)

Description copied from interface: IoAbsoluteReader

Gets enough bytes to fill the IoBuffer from the given index.

Specified by:

get in interface IoAbsoluteReader

getInt

int getInt(int index)

Description copied from interface: IoAbsoluteReader

Gets an int from the given index.

Specified by:

getInt in interface IoAbsoluteReader

cursor

ByteArray.Cursor cursor()

Get a cursor starting at index 0 (which may not be the start of the array).

cursor

ByteArray.Cursor cursor(int index)

Get a cursor starting at the given index.
