Constructor Detail

ChannelPutRequestImpl

protected ChannelPutRequestImpl(ChannelImpl channel,
                                ChannelPutRequester callback,
                                org.epics.pvdata.pv.PVStructure pvRequest)

Method Detail

create

public static ChannelPutRequestImpl create(ChannelImpl channel,
                                           ChannelPutRequester callback,
                                           org.epics.pvdata.pv.PVStructure pvRequest)

activate

protected void activate()

Overrides:

activate in class BaseRequestImpl

send

public void send(ByteBuffer buffer,
                 TransportSendControl control)

Description copied from interface: TransportSender

Called by transport. By this call transport gives callee ownership over the buffer. Calls on TransportSendControl instance must be made from calling thread. Moreover, ownership is valid only for the time of call of this method. NOTE: these limitations allow efficient implementation.

Specified by:

send in interface TransportSender

Overrides:

send in class BaseRequestImpl

Parameters:

buffer - buffer to send.

control - transport send control instance.

get

public void get()

Description copied from interface: ChannelPut

Get the current data.

Specified by:

get in interface ChannelPut

put

public void put(org.epics.pvdata.pv.PVStructure pvPutStructure,
                org.epics.pvdata.misc.BitSet bitSet)

Description copied from interface: ChannelPut

Put data to a channel. Completion status is reported by calling ChannelPutRequester.putDone() callback.

Specified by:

put in interface ChannelPut

Parameters:

pvPutStructure - The PVStructure that holds the putData.

bitSet - selects what fields to put.
