Methods

Modifier and Type	Method and Description
int	refCnt() Returns the reference count of this object.
boolean	release() Decreases the reference count by 1 and deallocates this object if the reference count reaches at 0.
boolean	release(int decrement) Decreases the reference count by the specified decrement and deallocates this object if the reference count reaches at 0.
ByteBuf	resumeIntermediaryDeallocations() Resumes the intermediary deallocation of the internal memory block of this buffer, suspended by ByteBuf.suspendIntermediaryDeallocations().
ByteBuf	retain() Increases the reference count by 1.
ByteBuf	retain(int increment) Increases the reference count by the specified increment.
ByteBuf	suspendIntermediaryDeallocations() Suspends the intermediary deallocation of the internal memory block of this buffer until asked via ByteBuf.resumeIntermediaryDeallocations().

Method Detail

refCnt

public final int refCnt()

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()

Description copied from interface: ReferenceCounted

Increases the reference count by 1.

retain

public final ByteBuf retain(int increment)

Description copied from interface: ReferenceCounted

Increases the reference count by the specified increment.

release

public final boolean release()

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)

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

suspendIntermediaryDeallocations

public final ByteBuf suspendIntermediaryDeallocations()

Description copied from interface: ByteBuf

Suspends the intermediary deallocation of the internal memory block of this buffer until asked via ByteBuf.resumeIntermediaryDeallocations(). An intermediary deallocation is usually made when the capacity of a buffer changes.

resumeIntermediaryDeallocations

public final ByteBuf resumeIntermediaryDeallocations()

Description copied from interface: ByteBuf

Resumes the intermediary deallocation of the internal memory block of this buffer, suspended by ByteBuf.suspendIntermediaryDeallocations().
