Member Function Documentation

attachAsClient() [1/2]

bool WireLink::attachAsClient

(

yarp::os::PortReader &

reader

)

Tag this WireLink as a client, sending data via the specified reader.

Parameters

reader

the reader to use when sending data.

Returns

true on success

Definition at line 92 of file WireLink.cpp.

attachAsClient() [2/2]

bool WireLink::attachAsClient

(

yarp::os::UnbufferedContactable &

port

)

Tag this WireLink as a client, sending data via the specified port.

Parameters

port	the port to use when sending data.

Returns

true on success

Definition at line 83 of file WireLink.cpp.

attachAsServer()

bool WireLink::attachAsServer

(

yarp::os::UnbufferedContactable &

port

)

Tag this WireLink as a server, receiving commands via the specified port.

Parameters

port	the port to monitor for commands.

Returns

true on success

Definition at line 101 of file WireLink.cpp.

callback()

bool WireLink::callback	(	PortWriter &	writer,
		PortReader &	reader,
		const std::string &	tag = ""
	)

Put a message in a stack to call later, asynchronously.

Used in implementation of thrift "oneway" messages.

Parameters

writer	message to send
reader	where to send the message
tag	string to prefix the message with

Returns

true on success

Definition at line 149 of file WireLink.cpp.

canRead()

bool WireLink::canRead

(

)

const

Returns

true if reading from the link is allowed.

Definition at line 161 of file WireLink.cpp.

canWrite()

bool WireLink::canWrite

(

)

const

Returns

true if writing is allowed over link.

Definition at line 156 of file WireLink.cpp.

isValid()

bool WireLink::isValid

(

)

const

Check if there is an association of some kind set up for this WireLink.

If not, data has nowhere to go.

Returns

True iff there is an association.

Definition at line 72 of file WireLink.cpp.

setOwner()

bool WireLink::setOwner

(

yarp::os::PortReader &

owner

)

Set the owner of this WireLink.

Data sent to this link will be passed on to the owner.

Parameters

owner

owner of this WireLink

Returns

true on success

Definition at line 77 of file WireLink.cpp.

setStreamingMode()

bool WireLink::setStreamingMode

(

bool

streaming

)

For a client WireLink, control whether replies to commands are expected.

Parameters

streaming

true if replies are unnecessary.

Returns

true on success

Definition at line 111 of file WireLink.cpp.

write() [1/2]

bool WireLink::write

(

PortWriter &

writer

)

Write a message to the associated port or reader.

Parameters

writer

the message to send.

Returns

true on success

Definition at line 117 of file WireLink.cpp.

write() [2/2]

bool WireLink::write	(	PortWriter &	writer,
		PortReader &	reader
	)

Write a message to the associated port or reader, and read a reply.

Parameters

writer	the message to send.
reader	a recipient for the reply.

Returns

true on success

Definition at line 130 of file WireLink.cpp.
