构造器详细资料

MemoryByteArray

public MemoryByteArray(int length)

Construct a new MemoryByteArray with a new array of the size given. It is assumed that none of the array is filled and readable.

参数:

length - the length to make the storage array

MemoryByteArray

public MemoryByteArray(byte[] b)

Construct a new MemoryByteArray to wrap the actual underlying byte array. This MemoryByteArray takes ownership of the array after construction and it should not be used outside of this object. It is assumed that the entire array is filled and readable.

参数:

b - the byte array that provides the actual storage

MemoryByteArray

public MemoryByteArray(byte[] b,
 int filledLength)

Construct a new MemoryByteArray to wrap the actual underlying byte array. This MemoryByteArray takes ownership of the array after construction and it should not be used outside of this object.

参数:

b - the byte array that provides the actual storage

filledLength - the index of the last byte in the array has data

抛出:

IndexOutOfBoundsException - if the given bounds don't fit within the byte array given

方法详细资料

internalPut

protected void internalPut(int index,
 byte b)

从类复制的说明: ByteArray

Stores the byte at the index given.

指定者:

internalPut 在类中 ByteArray<MemoryByteArray>

参数:

index - the location to store at

b - the byte to store

internalPut

protected int internalPut(int index,
 byte[] b,
 int offset,
 int length)

从类复制的说明: ByteArray

Stores the array of bytes at the given index.

指定者:

internalPut 在类中 ByteArray<MemoryByteArray>

参数:

index - the location to store at

b - the bytes to store

offset - the offset to start from in the byte array

length - the length of the byte array to store from the offset

返回:

the number of bytes actually stored

internalGet

protected int internalGet(int index)

从类复制的说明: ByteArray

Gets the byte at the index given.

指定者:

internalGet 在类中 ByteArray<MemoryByteArray>

参数:

index - the location to get from

返回:

the byte stored at the index

internalGet

protected int internalGet(int index,
 byte[] b,
 int offset,
 int length)

从类复制的说明: ByteArray
