SharedInputBuffer

public SharedInputBuffer(int bufferSize)

方法详细资料

fill

public int fill(ByteBuffer src)

updateCapacity

public void updateCapacity(CapacityChannel capacityChannel)
                    throws IOException

抛出:

IOException

read

public int read()
         throws IOException

从接口复制的说明: ContentInputBuffer

Reads one byte from this buffer. If the buffer is empty this method can throw a runtime exception. The exact type of runtime exception thrown by this method depends on implementation. This method returns -1 if the end of content stream has been reached.

指定者:

read 在接口中 ContentInputBuffer

返回:

one byte

抛出:

IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

从接口复制的说明: ContentInputBuffer

Reads up to len bytes of data from this buffer into an array of bytes. The exact number of bytes read depends how many bytes are stored in the buffer.

If off is negative, or len is negative, or off+len is greater than the length of the array b, this method can throw a runtime exception. The exact type of runtime exception thrown by this method depends on implementation. This method returns -1 if the end of content stream has been reached.

指定者:

read 在接口中 ContentInputBuffer

参数:

b - the buffer into which the data is read.

off - the start offset in array b at which the data is written.

len - the maximum number of bytes to read.

返回:

the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.

抛出:

IOException - if an I/O error occurs.

markEndStream

public void markEndStream()

hasData

public boolean hasData()

从类复制的说明: ExpandableBuffer

Determines if the buffer contains data.

Sets the mode to output.

覆盖:

hasData 在类中 ExpandableBuffer

返回:

true if there is data in the buffer, false otherwise.

capacity

public int capacity()

从类复制的说明: ExpandableBuffer

Returns available capacity of this buffer.

覆盖:

capacity 在类中 ExpandableBuffer

返回:

buffer length.

length

public int length()

从类复制的说明: ExpandableBuffer

Returns the length of this buffer.

Sets the mode to output.

覆盖:

length 在类中 ExpandableBuffer

返回:

buffer length.

abort

public void abort()

reset

public void reset()

isEndStream

public boolean isEndStream()
