方法详细资料

first

int first()

指定者:

first 在接口中 IoAbsoluteReader

指定者:

first 在接口中 IoAbsoluteWriter

返回:

the index of the first byte that can be accessed.

last

int last()

指定者:

last 在接口中 IoAbsoluteReader

指定者:

last 在接口中 IoAbsoluteWriter

返回:

the index after the last byte that can be accessed.

order

java.nio.ByteOrder order()

指定者:

order 在接口中 IoAbsoluteReader

指定者:

order 在接口中 IoAbsoluteWriter

返回:

the order of the bytes.

order

void order(java.nio.ByteOrder order)

Set the byte order of the array.

参数:

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

java.lang.Iterable<IoBuffer> getIoBuffers()

返回:

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

getSingleIoBuffer

IoBuffer getSingleIoBuffer()

返回:

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.

覆盖:

equals 在类中 java.lang.Object

参数:

other - The ByteArray we want to compare with

返回:

true if both ByteArray are equals

get

byte get(int index)

指定者:

get 在接口中 IoAbsoluteReader

参数:

index - The starting position

返回:

a byte from the given index.

get

void get(int index,
       IoBuffer bb)

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

指定者:

get 在接口中 IoAbsoluteReader

参数:

index - The starting position

bb - The IoBuffer that will be filled with the bytes

getInt

int getInt(int index)

指定者:

getInt 在接口中 IoAbsoluteReader

参数:

index - The starting position

返回:

an int from the given index.

cursor

ByteArray.Cursor cursor()

返回:

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

cursor

ByteArray.Cursor cursor(int index)

参数:

index - The starting point

返回:

a cursor starting at the given index.
