EmptyChannelBuffer
A big-endian Java heap buffer. It is recommended to use
ChannelBuffers.buffer(int)
and ChannelBuffers.wrappedBuffer(byte[])
instead of calling the
constructor explicitly.-

Method Details
-
factory
Description copied from interface:ChannelBuffer
Returns the factory which creates aChannelBuffer
whose type and defaultByteOrder
are same with this buffer. -
order
Description copied from interface:ChannelBuffer
Returns the endianness of this buffer. -
getShort
public short getShort(int index) Description copied from interface:ChannelBuffer
Gets a 16-bit short integer at the specified absoluteindex
in this buffer. This method does not modifyreaderIndex
orwriterIndex
of this buffer. -
getUnsignedMedium
public int getUnsignedMedium(int index) Description copied from interface:ChannelBuffer
Gets an unsigned 24-bit medium integer at the specified absoluteindex
in this buffer. This method does not modifyreaderIndex
orwriterIndex
of this buffer. -
getInt
public int getInt(int index) Description copied from interface:ChannelBuffer
Gets a 32-bit integer at the specified absoluteindex
in this buffer. This method does not modifyreaderIndex
orwriterIndex
of this buffer. -
getLong
public long getLong(int index) Description copied from interface:ChannelBuffer
Gets a 64-bit long integer at the specified absoluteindex
in this buffer. This method does not modifyreaderIndex
orwriterIndex
of this buffer. -
setShort
public void setShort(int index, int value) Description copied from interface:ChannelBuffer
Sets the specified 16-bit short integer at the specified absoluteindex
in this buffer. The 16 high-order bits of the specified value are ignored. This method does not modifyreaderIndex
orwriterIndex
of this buffer. -
setMedium
public void setMedium(int index, int value) Description copied from interface:ChannelBuffer
Sets the specified 24-bit medium integer at the specified absoluteindex
in this buffer. Please note that the most significant byte is ignored in the specified value. This method does not modifyreaderIndex
orwriterIndex
of this buffer. -
setInt
public void setInt(int index, int value) Description copied from interface:ChannelBuffer
Sets the specified 32-bit integer at the specified absoluteindex
in this buffer. This method does not modifyreaderIndex
orwriterIndex
of this buffer. -
setLong
public void setLong(int index, long value) Description copied from interface:ChannelBuffer
Sets the specified 64-bit long integer at the specified absoluteindex
in this buffer. This method does not modifyreaderIndex
orwriterIndex
of this buffer. -
duplicate
Description copied from interface:ChannelBuffer
Returns a buffer which shares the whole region of this buffer. Modifying the content of the returned buffer or this buffer affects each other's content while they maintain separate indexes and marks. This method is identical tobuf.slice(0, buf.capacity())
. This method does not modifyreaderIndex
orwriterIndex
of this buffer. -
copy
Description copied from interface:ChannelBuffer
Returns a copy of this buffer's sub-region. Modifying the content of the returned buffer or this buffer does not affect each other at all. This method does not modifyreaderIndex
orwriterIndex
of this buffer.
