Method Details

copy

public DatagramPacket copy()

Description copied from interface: ByteBufHolder

Creates a deep copy of this ByteBufHolder.

Specified by:

copy in interface ByteBufHolder

duplicate

public DatagramPacket duplicate()

Description copied from interface: ByteBufHolder

Duplicates this ByteBufHolder. Be aware that this will not automatically call ByteBufHolder.retain().

Specified by:

duplicate in interface ByteBufHolder

retainedDuplicate

public DatagramPacket retainedDuplicate()

Description copied from interface: ByteBufHolder

Duplicates this ByteBufHolder. This method returns a retained duplicate unlike ByteBufHolder.duplicate().

Specified by:

retainedDuplicate in interface ByteBufHolder

• ByteBuf.retainedDuplicate()

replace

public DatagramPacket replace(ByteBuf content)

Description copied from interface: ByteBufHolder

Returns a new ByteBufHolder which contains the specified content.

Specified by:

replace in interface ByteBufHolder

retain

public DatagramPacket retain()

Description copied from interface: ReferenceCounted

Increases the reference count by 1.

Specified by:

retain in interface AddressedEnvelope<ByteBuf, java.net.InetSocketAddress>

Specified by:

retain in interface ByteBufHolder

Specified by:

retain in interface ReferenceCounted

touch in class DefaultAddressedEnvelope<ByteBuf, java.net.InetSocketAddress>

touch

public DatagramPacket touch(java.lang.Object hint)

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 via ResourceLeakDetector.

Specified by:

touch in interface AddressedEnvelope<ByteBuf, java.net.InetSocketAddress>

Specified by:

touch in interface ByteBufHolder

Specified by:

touch in interface ReferenceCounted

Overrides:

touch in class DefaultAddressedEnvelope<ByteBuf, java.net.InetSocketAddress>
