构造方法详细信息

View

public View(Buffer buffer,
            int mark,
            int get,
            int put,
            int access)

参数：

buffer - The Buffer on which we are presenting a View.

mark - The initial value of the mark index

get - The initial value of the get index

put - The initial value of the put index

access - The access level - one of the constants from Buffer.

View

public View(Buffer buffer)

View

public View()

方法详细信息

update

public void update(Buffer buffer)

Update view to buffer

update

public void update(int get,
                   int put)

array

public byte[] array()

从接口 Buffer 复制的描述

Get the underlying array, if one exists.

返回：

The Buffer.array() from the underlying buffer.

buffer

public Buffer buffer()

从接口 Buffer 复制的描述

Get the underlying buffer. If this buffer wraps a backing buffer.

指定者：

接口 Buffer 中的 buffer

覆盖：

类 AbstractBuffer 中的 buffer

返回：

The Buffer.buffer() from the underlying buffer.

capacity

public int capacity()

从接口 Buffer 复制的描述

The capacity of the buffer. This is the maximum putIndex that may be set.

返回：

The Buffer.capacity() of the underlying buffer.

clear

public void clear()

从接口 Buffer 复制的描述

Clear the buffer. getIndex=0, putIndex=0.

指定者：

接口 Buffer 中的 clear

覆盖：

类 AbstractBuffer 中的 clear

compact

public void compact()

从接口 Buffer 复制的描述

Compact the buffer by discarding bytes before the postion (or mark if set). Bytes from the getIndex (or mark) to the putIndex are moved to the beginning of the buffer and the values adjusted accordingly.

指定者：

接口 Buffer 中的 compact

覆盖：

类 AbstractBuffer 中的 compact

equals

public boolean equals(Object obj)

覆盖：

类 AbstractBuffer 中的 equals

isReadOnly

public boolean isReadOnly()

指定者：

接口 Buffer 中的 isReadOnly

覆盖：

类 AbstractBuffer 中的 isReadOnly

返回：

Whether the underlying buffer is read only

isVolatile

public boolean isVolatile()

指定者：

接口 Buffer 中的 isVolatile

覆盖：

类 AbstractBuffer 中的 isVolatile

返回：

Whether the underlying buffer is volatile

peek

public byte peek(int index)

从接口 Buffer 复制的描述

Get the byte at a specific index in the buffer.

参数：

index - an int value

返回：

The result of calling Buffer.peek(int) on the underlying buffer

peek

public int peek(int index,
                byte[] b,
                int offset,
                int length)

参数：

index - an int value

b - The byte array to peek into

offset - The offset into the array to start peeking

length - an int value

返回：

The result of calling Buffer.peek(int, byte[], int, int) on the underlying buffer

peek

public Buffer peek(int index,
                   int length)

指定者：

接口 Buffer 中的 peek
