Class SegmentedDatagramPacket

java.lang.Object

io.netty.channel.DefaultAddressedEnvelope<ByteBuf, java.net.InetSocketAddress>

io.netty.channel.socket.DatagramPacket

io.netty.channel.unix.SegmentedDatagramPacket

All Implemented Interfaces:

Direct Known Subclasses:

SegmentedDatagramPacket

public class SegmentedDatagramPacket
extends DatagramPacket

Allows to use GSO if the underlying OS supports it. Before using this you should ensure your system support it.

Constructor Details

SegmentedDatagramPacket

public SegmentedDatagramPacket(ByteBuf data,
 int segmentSize,
 java.net.InetSocketAddress recipient)

Create a new instance.

Parameters:

data - the ByteBuf which must be continguous.

segmentSize - the segment size.

recipient - the recipient.

SegmentedDatagramPacket

public SegmentedDatagramPacket(ByteBuf data,
 int segmentSize,
 java.net.InetSocketAddress recipient,
 java.net.InetSocketAddress sender)

Create a new instance.

Parameters:

data - the ByteBuf which must be continguous.

segmentSize - the segment size.

recipient - the recipient.

Method Details

segmentSize

public int segmentSize()

Return the size of each segment (the last segment can be smaller).

Returns:

size of segments.

copy

public SegmentedDatagramPacket copy()

Description copied from interface: ByteBufHolder

Creates a deep copy of this ByteBufHolder.

Specified by:

copy in interface ByteBufHolder

Overrides:

copy in class DatagramPacket

duplicate

public SegmentedDatagramPacket 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

Overrides:

duplicate in class DatagramPacket

retainedDuplicate

public SegmentedDatagramPacket retainedDuplicate()

Description copied from interface: ByteBufHolder

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

Specified by:

retainedDuplicate in interface ByteBufHolder

Overrides:

retainedDuplicate in class DatagramPacket

See Also:

• ByteBuf.retainedDuplicate()

replace

public SegmentedDatagramPacket replace(ByteBuf content)

Description copied from interface: ByteBufHolder

Returns a new ByteBufHolder which contains the specified content.

Specified by:

replace in interface ByteBufHolder

Overrides:

replace in class DatagramPacket

retain

public SegmentedDatagramPacket 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

Overrides:

retain in class DatagramPacket

retain

public SegmentedDatagramPacket retain(int increment)

Description copied from interface: ReferenceCounted

Increases the reference count by the specified increment.

Specified by:

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

Specified by:

retain in interface ByteBufHolder

Specified by:

retain in interface ReferenceCounted

Overrides:

retain in class DatagramPacket

touch

public SegmentedDatagramPacket touch()

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 via ResourceLeakDetector. This method is a shortcut to touch(null).

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 DatagramPacket

touch

public SegmentedDatagramPacket 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 DatagramPacket
