Method Detail

refCnt

public final int refCnt()

Deprecated.

Description copied from interface: ReferenceCounted

Returns the reference count of this object. If 0, it means this object has been deallocated.

retain

public final ByteBuf retain()

Deprecated.

Description copied from interface: ReferenceCounted

Increases the reference count by 1.

Specified by:

retain in interface ReferenceCounted

Specified by:

retain in class ByteBuf

retain

public final ByteBuf retain(int increment)

Deprecated.

Description copied from interface: ReferenceCounted

Increases the reference count by the specified increment.

Specified by:

retain in interface ReferenceCounted

Specified by:

retain in class ByteBuf

release

public final boolean release()

Deprecated.

Description copied from interface: ReferenceCounted

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

Returns:

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

release

public final boolean release(int decrement)

Deprecated.

Description copied from interface: ReferenceCounted

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

Returns:

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

internalNioBuffer

public java.nio.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 java.nio.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
