AbstractReferenceCountedByteBuf

protected AbstractReferenceCountedByteBuf(int maxCapacity)

方法详细资料

refCnt

public int refCnt()

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.

setRefCnt

protected final void setRefCnt(int refCnt)

An unsafe operation intended for use by a subclass that sets the reference count of the buffer directly

retain

public ByteBuf retain()

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 ByteBuf retain(int increment)

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 boolean release()

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 boolean release(int decrement)

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

deallocate

protected abstract void deallocate()

Called once refCnt() is equals 0.
