Detailed Description

Following are the interfaces for all the properties in alphabetic order of they base type (i.e. double, long, pattern and string). They all follow the same patterns, described in the documents "BACI specifications" and "Application of BACI for ACS 1.0". The patterns are: P<type>, the base class of a Property, which subclasses RO<type>, a read-only version and RW<type>, a read-write version of the Property class. Additional patterns are for Properties that return sequences of values, i.e P<type>Seq, RO<type>Seq and RW<type>Seq. Here, only the double type occurence of a pattern is documented in detail, others are equivalent, unless the difference is explicitely commented.

Note that all Property patterns are typesafe, i.e. they return the explicit type of the property value and its characteristics - no casting or use of type any is required. Even the callbacks and in some cases the Monitors are of the correct type.

The interfaces have been all obtained by a generator, that expands meta-IDL template definitions. The comments that start with the symbol @ denote the templates used by the generator The generator is not yet available for ACS1.0.

Member Function Documentation

Monitordouble ACS::Pdouble::create_monitor	(	in CBdouble	cb,
		in CBDescIn	desc
	)

Start continuous monitoring (with default time interval). As in all asynchronous requests, a callback object cb and its descriptor desc have to be provided. See Callback for more details. 3AC90A260281

Monitordouble ACS::Pdouble::create_postponed_monitor	(	in Time	start_time,
		in CBdouble	cb,
		in CBDescIn	desc
	)

Register a monitor whose beginning will be postponed until the specified start_time, which is given in absolute time. See create_monitor for more details on monitors. 3AC90A2602B2

void ACS::Pdouble::get_async	(	in CBdouble	cb,
		in CBDescIn	desc
	)

Request one value through callback. The callback cb and its desciptor desc have to be created by the client. The callback is of type CBdouble, because it explicitely carries a value of type double. 3AC90A26024D

long ACS::Pdouble::get_history	(	in long	n_last_values,
		out doubleSeq	vs,
		out TimeSeq	ts
	)

Read n_last_lalues or all values (whichever is less) from the server�s local archive. If n_last_values is 0, then read complete local archive. Method returns number of actually transmitted values. 3AC90A260262

double ACS::Pdouble::get_sync ( out ACSErr::Completion c )

Synchronous call that returns the value of the property in the correct type, no casting is required. 3AC90A26022F
