Constructor Detail

ChannelPutGetRequestImpl

protected ChannelPutGetRequestImpl(ChannelImpl channel,
                                   ChannelPutGetRequester callback,
                                   org.epics.pvdata.pv.PVStructure pvRequest)

Method Detail

create

public static ChannelPutGetRequestImpl create(ChannelImpl channel,
                                              ChannelPutGetRequester 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.

putGet

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

Description copied from interface: ChannelPutGet

Issue a put/get request. If process was requested when the ChannelPutGet was created this is a put, process, get. Completion status is reported by calling ChannelPutGetRequester.putGetDone() callback.

Specified by:

putGet in interface ChannelPutGet

Parameters:

pvPutStructure - The PVStructure that holds the putData.

bitSet - putPVStructure bit-set (selects what fields to put).

getGet

public void getGet()

Description copied from interface: ChannelPutGet

Get the get PVStructure. The record will not be processed. Completion status is reported by calling ChannelPutGetRequester.getGetDone() callback.

Specified by:

getGet in interface ChannelPutGet

getPut

public void getPut()

Description copied from interface: ChannelPutGet

Get the put PVStructure. The record will not be processed. Completion status is reported by calling ChannelPutGetRequester.getPutDone() callback.

Specified by:

getPut in interface ChannelPutGet
