Doc from io.netty.buffer.ByteBuf.asReadOnly.

Returns a read-only version of this buffer.

duplicateback to summary
public ByteBuf duplicate()

Overrides io.netty.buffer.WrappedCompositeByteBuf.duplicate.

Doc from io.netty.buffer.ByteBuf.duplicate.

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 does not modify readerIndex or writerIndex of this buffer.

The reader and writer marks will not be duplicated. Also be aware that this method will NOT call retain() and so the reference count will NOT be increased.

Returns:ByteBuf

A buffer whose readable content is equivalent to the buffer returned by slice(). However this buffer will share the capacity of the underlying buffer, and therefore allows access to all of the underlying content if necessary.

orderback to summary
public ByteBuf order(ByteOrder endianness)

Overrides io.netty.buffer.WrappedCompositeByteBuf.order.

Doc from io.netty.buffer.ByteBuf.order.

Returns a buffer with the specified endianness which shares the whole region, indexes, and marks of this buffer. Modifying the content, the indexes, or the marks of the returned buffer or this buffer affects each other's content, indexes, and marks. If the specified endianness is identical to this buffer's byte order, this method can return this. This method does not modify readerIndex or writerIndex of this buffer.

readRetainedSliceback to summary
public ByteBuf readRetainedSlice(int length)

Overrides io.netty.buffer.WrappedCompositeByteBuf.readRetainedSlice.

Doc from io.netty.buffer.ByteBuf.readRetainedSlice.

Returns a new retained slice of this buffer's sub-region starting at the current readerIndex and increases the readerIndex by the size of the new slice (= length).

Note that this method returns a retained buffer unlike readSlice(int). This method behaves similarly to readSlice(...).retain() except that this method may return a buffer implementation that produces less garbage.

Parameters
length:int

the size of the new slice

Returns:ByteBuf

the newly created slice

public ByteBuf readSlice(int length)

Overrides io.netty.buffer.WrappedCompositeByteBuf.readSlice.

Doc from io.netty.buffer.ByteBuf.readSlice.

Returns a new slice of this buffer's sub-region starting at the current readerIndex and increases the readerIndex by the size of the new slice (= length).

Also be aware that this method will NOT call retain() and so the reference count will NOT be increased.

Parameters
length:int

Returns:ByteBuf

Implements io.netty.util.ReferenceCounted.release.

Doc from io.netty.util.ReferenceCounted.release.

Decreases the reference count by 1 and deallocates this object if the reference count reaches at 0.

Returns:boolean

true if and only if the reference count became 0 and this object has been deallocated

public ByteBuf retainedDuplicate()

Overrides io.netty.buffer.WrappedCompositeByteBuf.retainedDuplicate.

Doc from io.netty.buffer.ByteBuf.retainedDuplicate.

Returns a retained 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 to buf.slice(0, buf.capacity()). This method does not modify readerIndex or writerIndex of this buffer.

Note that this method returns a retained buffer unlike slice(int, int). This method behaves similarly to duplicate().retain() except that this method may return a buffer implementation that produces less garbage.

Doc from io.netty.buffer.ByteBuf.retainedSlice.

Returns a retained slice of this buffer's readable bytes. 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 to buf.slice(buf.readerIndex(), buf.readableBytes()). This method does not modify readerIndex or writerIndex of this buffer.
