                    int length)
             throws java.io.IOException

Deprecated.

Description copied from class: ByteBuf

Transfers the content of the specified source channel to this buffer starting at the specified absolute index. This method does not modify readerIndex or writerIndex of this buffer.

Specified by:

setBytes in class ByteBuf

length - the maximum number of bytes to transfer

Returns:

the actual number of bytes read in from the specified channel. -1 if the specified channel is closed or it reached EOF.

Throws:

java.io.IOException - if the specified channel threw an exception during I/O

setBytes

public int setBytes(int index,
                    java.nio.channels.FileChannel in,
                    long position,
                    int length)
             throws java.io.IOException

Deprecated.

Description copied from class: ByteBuf

Transfers the content of the specified source channel starting at the given file position to this buffer starting at the specified absolute index. This method does not modify readerIndex or writerIndex of this buffer. This method does not modify the channel's position.

Specified by:

setBytes in class ByteBuf

position - the file position at which the transfer is to begin

length - the maximum number of bytes to transfer

Returns:

the actual number of bytes read in from the specified channel. -1 if the specified channel is closed or it reached EOF.

Throws:

java.io.IOException - if the specified channel threw an exception during I/O

nioBufferCount

public int nioBufferCount()

Deprecated.

Description copied from class: ByteBuf

Returns the maximum number of NIO ByteBuffers that consist this buffer. Note that ByteBuf.nioBuffers() or ByteBuf.nioBuffers(int, int) might return a less number of ByteBuffers.

Specified by:

nioBufferCount in class ByteBuf

Returns:

-1 if this buffer has no underlying ByteBuffer. the number of the underlying ByteBuffers if this buffer has at least one underlying ByteBuffer. Note that this method does not return 0 to avoid confusion.

nioBuffers

public java.nio.ByteBuffer[] nioBuffers(int index,
                                        int length)

Deprecated.

Description copied from class: ByteBuf

Exposes this buffer's bytes as an NIO ByteBuffer's for the specified index and length The returned buffer either share or contains the copied content of this buffer, while changing the position and limit of the returned NIO buffer does not affect the indexes and marks of this buffer. This method does not modify readerIndex or writerIndex of this buffer. Please note that the returned NIO buffer will not see the changes of this buffer if this buffer is a dynamic buffer and it adjusted its capacity.

forEachByte

public int forEachByte(int index,
                       int length,
                       ByteProcessor processor)

Deprecated.

Description copied from class: ByteBuf

Iterates over the specified area of this buffer with the specified processor in ascending order. (i.e. index, (index + 1), .. (index + length - 1))

Overrides:

forEachByte in class AbstractByteBuf

Returns:

-1 if the processor iterated to or beyond the end of the specified area. The last-visited index If the ByteProcessor.process(byte) returned false.

forEachByteDesc

public int forEachByteDesc(int index,
                           int length,
                           ByteProcessor processor)

Deprecated.

Description copied from class: ByteBuf

Iterates over the specified area of this buffer with the specified processor in descending order. (i.e. (index + length - 1), (index + length - 2), ... index)

Overrides:

forEachByteDesc in class AbstractByteBuf

Returns:

-1 if the processor iterated to or beyond the beginning of the specified area. The last-visited index If the ByteProcessor.process(byte) returned false.
