DataBufferFactory |
factory()
Return the
DataBufferFactory that created this buffer. |
int |
indexOf(IntPredicate predicate,
int fromIndex)
Return the index of the first byte in this buffer that matches the given
predicate.
|
int |
lastIndexOf(IntPredicate predicate,
int fromIndex)
Return the index of the last byte in this buffer that matches the given
predicate.
|
byte |
read()
Read a single byte from the current reading position of this data buffer.
|
DataBuffer |
read(byte[] destination)
Read this buffer's data into the specified destination, starting at the current
reading position of this buffer.
|
DataBuffer |
read(byte[] destination,
int offset,
int length)
Read at most
length bytes of this buffer into the specified destination,
starting at the current reading position of this buffer. |
int |
readableByteCount()
Return the number of bytes that can be read from this data buffer.
|
DataBuffer |
slice(int index,
int length)
Create a new
DataBuffer whose contents is a shared subsequence of this
data buffer's content. |
DataBuffer |
write(byte b)
Write a single byte into this buffer at the current writing position.
|
DataBuffer |
write(byte[] source)

of this buffer.
|
DataBuffer |
write(byte[] source,
int offset,
int length)
Write at most
length bytes of the given source into this buffer, starting
at the current writing position of this buffer. |
DataBuffer |
write(ByteBuffer... buffers)

ByteBuffer to this buffer, starting at the current
writing position. |
DataBuffer |
write(DataBuffer... buffers)

DataBuffer whose contents is a shared subsequence of this
data buffer's content. Data between this data buffer and the returned buffer is
shared; though changes in the returned buffer's position will not be reflected
in the reading nor writing position of this data buffer.index - the index at which to start the slicelength - the length of the sliceByteBuffer asByteBuffer()
ByteBuffer. Data between this
DataBuffer and the returned ByteBuffer is shared; though
changes in the returned buffer's position
will not be reflected in the reading nor writing position of this data buffer.InputStream asInputStream()
InputStream. Both data and position are
shared between the returned stream and this data buffer.OutputStream asOutputStream()
OutputStream. Both data and position are
shared between the returned stream and this data buffer.
