AbstractDerivedByteBuf

protected AbstractDerivedByteBuf(int maxCapacity)

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

touch

public final ByteBuf touch()

已过时。

从接口复制的说明: ReferenceCounted

Records the current access location of this object for debugging purposes. If this object is determined to be leaked, the information recorded by this operation will be provided to you via ResourceLeakDetector. This method is a shortcut to touch(null).

指定者:

touch 在接口中 ReferenceCounted

指定者:

touch 在类中 ByteBuf

touch

public final ByteBuf touch(java.lang.Object hint)

已过时。

从接口复制的说明: ReferenceCounted

Records the current access location of this object with an additional arbitrary information for debugging purposes. If this object is determined to be leaked, the information recorded by this operation will be provided to you via ResourceLeakDetector.

指定者:

touch 在接口中 ReferenceCounted

指定者:

touch 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

isReadOnly

public boolean isReadOnly()

已过时。

从类复制的说明: ByteBuf

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

覆盖:

isReadOnly 在类中 AbstractByteBuf

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

另请参阅:

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

isContiguous

public boolean isContiguous()

已过时。

从类复制的说明: 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.

isContiguous 在类中 ByteBuf
