Method Detail
-
refCnt
public final int refCnt()
Deprecated.Description copied from interface:ReferenceCounted
Returns the reference count of this object. If0
, it means this object has been deallocated.
-
retain
public final ByteBuf retain()
Deprecated.Description copied from interface:ReferenceCounted
Increases the reference count by1
.- Specified by:
retain
in interfaceReferenceCounted
- Specified by:
retain
in classByteBuf
-
retain
public final ByteBuf retain(int increment)
Deprecated.Description copied from interface:ReferenceCounted
Increases the reference count by the specifiedincrement
.- Specified by:
retain
in interfaceReferenceCounted
- Specified by:
retain
in classByteBuf
-
touch
public final ByteBuf touch()
Deprecated.Description copied from interface: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 viaResourceLeakDetector
. This method is a shortcut totouch(null)
.- Specified by:
touch
in interfaceReferenceCounted
- Specified by:
touch
in classByteBuf
-
touch
public final ByteBuf touch(java.lang.Object hint)
Deprecated.Description copied from interface: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 viaResourceLeakDetector
.- Specified by:
touch
in interfaceReferenceCounted
- Specified by:
touch
in classByteBuf
-
release
public final boolean release()
Deprecated.Description copied from interface:ReferenceCounted
Decreases the reference count by1
and deallocates this object if the reference count reaches at0
.- Returns:
true
if and only if the reference count became0
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 specifieddecrement
and deallocates this object if the reference count reaches at0
.- Returns:
true
if and only if the reference count became0
and this object has been deallocated
-
isReadOnly
public boolean isReadOnly()
Deprecated.Description copied from class:ByteBuf
Returnstrue
if and only if this buffer is read-only.- Overrides:
isReadOnly
in classAbstractByteBuf
-
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 classByteBuf
-
nioBuffer
public java.nio.ByteBuffer nioBuffer(int index, int length)
Deprecated.Description copied from class:ByteBuf
Exposes this buffer's sub-region as an NIOByteBuffer
. 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 modifyreaderIndex
orwriterIndex
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 classByteBuf
- See Also:
ByteBuf.nioBufferCount()
,ByteBuf.nioBuffers()
,ByteBuf.nioBuffers(int, int)
-
isContiguous
public boolean isContiguous()
Deprecated.Description copied from class:ByteBuf
Returnstrue
if thisByteBuf
implementation is backed by a single memory region. Composite buffer implementations must return false even if they currently hold ≤ 1 components. For buffers that returntrue
, it's guaranteed that a successful call toByteBuf.discardReadBytes()
will increase the value ofByteBuf.maxFastWritableBytes()
by the currentreaderIndex
.This method will return
false
by default, and afalse
return value does not necessarily mean that the implementation is composite or that it is not backed by a single memory region.- Overrides:
isContiguous
in classByteBuf
