    • capacity

      public int capacity()
      Description copied from class: ByteBuf
      Returns the number of bytes (octets) this buffer can contain.
      Specified by:
      capacity in class ByteBuf
    • capacity

      public ByteBuf capacity(int newCapacity)
      Description copied from class: ByteBuf
      Adjusts the capacity of this buffer. If the newCapacity is less than the current capacity, the content of this buffer is truncated. If the newCapacity is greater than the current capacity, the buffer is appended with unspecified data whose length is (newCapacity - currentCapacity).
      Specified by:
      capacity in class ByteBuf
    • arrayOffset

      public int arrayOffset()
      Description copied from class: ByteBuf

    • memoryAddress

      public long memoryAddress()
      Description copied from class: ByteBuf
      Returns the low-level memory address that point to the first byte of ths backing data.
      Specified by:
      memoryAddress in class ByteBuf
    • nioBuffer

      public ByteBuffer nioBuffer(int index, int length)
      Description copied from class: ByteBuf
      Exposes this buffer's sub-region as an NIO ByteBuffer. 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.
      Specified by:
      nioBuffer in class ByteBuf
      See Also:
    • nioBuffers

      public ByteBuffer[] nioBuffers(int index, int length)
      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.
      Specified by:

      See Also:
    • copy

      public ByteBuf copy(int index, int length)
      Description copied from class: ByteBuf
      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 modify readerIndex or writerIndex of this buffer.
      Specified by:
      copy in class ByteBuf
    • retainedSlice

      public ByteBuf retainedSlice(int index, int length)
      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 AbstractByteBuf
    • 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 AbstractByteBuf
      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 AbstractByteBuf
