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.

Method Details

first

int first()

Specified by:

first in interface IoAbsoluteReader

Specified by:

first in interface IoAbsoluteWriter

Returns:

the index of the first byte that can be accessed.

last

int last()

Specified by:

last in interface IoAbsoluteReader

Specified by:

last in interface IoAbsoluteWriter

Returns:

the index after the last byte that can be accessed.

order

ByteOrder order()

Specified by:

order in interface IoAbsoluteReader

Specified by:

order in interface IoAbsoluteWriter

Returns:

the order of the bytes.

order

void order(ByteOrder order)

Set the byte order of the array.

Parameters:

order - The ByteOrder to use

free

void free()

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

getIoBuffers

Iterable<IoBuffer> getIoBuffers()

Returns:

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

getSingleIoBuffer

IoBuffer getSingleIoBuffer()

Returns:

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(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 Object

Parameters:

other - The ByteArray we want to compare with

Returns:

true if both ByteArray are equals

get

byte get(int index)

Specified by:

get in interface IoAbsoluteReader

Parameters:

index - The starting position

Returns:

a byte from the given index.

get

void get(int index,
 IoBuffer bb)

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

Specified by:

get in interface IoAbsoluteReader

Parameters:

index - The starting position

bb - The IoBuffer that will be filled with the bytes

getInt

int getInt(int index)

Specified by:

getInt in interface IoAbsoluteReader

Parameters:

index - The starting position

Returns:

an int from the given index.

cursor

ByteArray.Cursor cursor()

Returns:

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

cursor

ByteArray.Cursor cursor(int index)

Parameters:

index - The starting point

Returns:

a cursor starting at the given index.
