      • order

        public ByteBuf order​(java.nio.ByteOrder endianness)
        Description copied from class: ByteBuf
        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.
        Overrides:
        order in class SimpleLeakAwareCompositeByteBuf
      • slice

        public ByteBuf slice()
        Description copied from class: ByteBuf
        Returns a 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.

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

        Overrides:
        slice in class SimpleLeakAwareCompositeByteBuf
      • retainedSlice

        public ByteBuf retainedSlice()
        Description copied from class: ByteBuf
        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.

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

        Overrides:
        retainedSlice in class SimpleLeakAwareCompositeByteBuf
      • slice

        public ByteBuf slice​(int index,
                             int length)
        Description copied from class: ByteBuf
        Returns a slice of this buffer's sub-region. 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.

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

        Overrides:
        slice in class SimpleLeakAwareCompositeByteBuf
      • retainedSlice

        public ByteBuf retainedSlice​(int index,

        Description copied from class: ByteBuf
        Returns a retained slice of this buffer's sub-region. 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.

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

        Overrides:
        retainedSlice in class SimpleLeakAwareCompositeByteBuf
      • duplicate

        public ByteBuf duplicate()
        Description copied from class: ByteBuf
        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 ByteBuf.retain() and so the reference count will NOT be increased.

        Overrides:
        duplicate in class SimpleLeakAwareCompositeByteBuf
        Returns:
        A buffer whose readable content is equivalent to the buffer returned by ByteBuf.slice(). However this buffer will share the capacity of the underlying buffer, and therefore allows access to all of the underlying content if necessary.
      • retainedDuplicate

        public ByteBuf retainedDuplicate()
        Description copied from class: ByteBuf
        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 ByteBuf.slice(int, int). This method behaves similarly to duplicate().retain() except that this method may return a buffer implementation that produces less garbage.

        Overrides:
        retainedDuplicate in class SimpleLeakAwareCompositeByteBuf
      • readSlice

        public ByteBuf readSlice​(int length)
        Description copied from class: ByteBuf
        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 ByteBuf.retain() and so the reference count will NOT be increased.

        Overrides:
        readSlice in class SimpleLeakAwareCompositeByteBuf
        Parameters:
        length - the size of the new slice
        Returns:

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

        Overrides:
        readRetainedSlice in class SimpleLeakAwareCompositeByteBuf
        Parameters:
        length - the size of the new slice
        Returns:

      • discardReadBytes

        public CompositeByteBuf discardReadBytes()
        Description copied from class: ByteBuf

        Please refer to the class documentation for more detailed explanation.

        Overrides:

        Description copied from class: ByteBuf
        Expands the buffer ByteBuf.capacity() to make sure the number of writable bytes is equal to or greater than the specified value. Unlike ByteBuf.ensureWritable(int), this method returns a status code.
        Overrides:
        ensureWritable in class WrappedCompositeByteBuf
        Parameters:
        minWritableBytes - the expected minimum number of writable bytes
        force - When ByteBuf.writerIndex() + minWritableBytes > ByteBuf.maxCapacity():
        • true - the capacity of the buffer is expanded to ByteBuf.maxCapacity()
        • false - the capacity of the buffer is unchanged
        Returns:
        0 if the buffer has enough writable bytes, and its capacity is unchanged. 1 if the buffer does not have enough bytes, and its capacity is unchanged. 2 if the buffer has enough writable bytes, and its capacity has been increased. 3 if the buffer does not have enough bytes, but its capacity has been increased to its maximum.
