已过时。

方法详细资料

refCnt

public final int refCnt()

已过时。

从接口复制的说明: ReferenceCounted

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

retain

public final ByteBuf retain()

已过时。

从接口复制的说明: ReferenceCounted

Increases the reference count by 1.

指定者:

retain 在接口中 ReferenceCounted

指定者:

retain 在类中 ByteBuf

retain

public final ByteBuf retain(int increment)

已过时。

从接口复制的说明: ReferenceCounted

Increases the reference count by the specified increment.

指定者:

retain 在接口中 ReferenceCounted

指定者:

retain 在类中 ByteBuf

release

public final boolean release()

已过时。

从接口复制的说明: ReferenceCounted

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

返回:

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

release

public final boolean release(int decrement)

已过时。

从接口复制的说明: ReferenceCounted

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

返回:

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)

已过时。

从类复制的说明: ByteBuf

Internal use only: Exposes the internal NIO buffer.

指定者:

internalNioBuffer 在类中 ByteBuf

nioBuffer

public java.nio.ByteBuffer nioBuffer(int index,
                            int length)

已过时。

从类复制的说明: 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.

指定者:

nioBuffer 在类中 ByteBuf
