isReadOnly

public boolean isReadOnly()

Deprecated.

Description copied from class: ByteBuf

Returns true if and only if this buffer is read-only.

Overrides:

isReadOnly in class AbstractByteBuf

internalNioBuffer

public ByteBuffer internalNioBuffer(int index,
 int length)

Deprecated.

Description copied from class: ByteBuf

Internal use only: Exposes the internal NIO buffer.

Specified by:

internalNioBuffer in class ByteBuf

nioBuffer

public ByteBuffer nioBuffer(int index,
 int length)

Deprecated.

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:

• ByteBuf.nioBufferCount()
• ByteBuf.nioBuffers()
• ByteBuf.nioBuffers(int, int)

isContiguous

public boolean isContiguous()

Deprecated.

Description copied from class: ByteBuf

Returns true if this ByteBuf implementation is backed by a single memory region. Composite buffer implementations must return false even if they currently hold ≤ 1 components. For buffers that return true, it's guaranteed that a successful call to ByteBuf.discardReadBytes() will increase the value of ByteBuf.maxFastWritableBytes() by the current readerIndex.

This method will return false by default, and a false return value does not necessarily mean that the implementation is composite or that it is not backed by a single memory region.

Overrides:

isContiguous in class ByteBuf
