Detailed Description

template<class T>
class DevIO< T >

Device I/O implementation class. This class is a base class for providing input/output implementations to the Property class. (copied from ticsDevIO and converted into abstract class)

template<class T>

virtual bool DevIO< T >::initializeValue ( ) [inline, virtual]

The return value of initializeValue function tells the constructor of property if it has to set initial value of DevIO to default value or not. The default value of property is read from CDB. InitializeValue: If true ACS will try to automatically set the value upon initialization.

Returns:: bool - If true attempt to initialize the value at instanciation.

Reimplemented in LongDevIO, DevIOTime, DevIOMem< T >, TMCDB::MCtestDevIO< T >, TMCDB::MCtestDevIOSeq< T >, TMCDB::MCtestDevIONoIncremental< T >, TMCDB::MCtestDevIOSeqNoIncremental< T >, TMCDB::MCtestDevIO< double >, and TMCDB::MCtestDevIOSeq< ACS::doubleSeq >.

template<class T>

virtual T DevIO< T >::read ( ACS::Time & timestamp ) [inline, virtual]

Method to read a value. It has to be override by implementation of DevIO. If the method is not overriden, and it is called than ACSErrTypeCommon::NotImplementedExImpl exception is thrown!

Parameters:

timestamp

timestamp of reading

Exceptions:

	any	of ACS exceptions can be thrown
	ACSErr::ACSbaseExImpl

Returns:: read value

Reimplemented in CosDevIO, SinDevIO, DevIOTime, DevIOMem< T >, TestDevIO, TestErrorDevIO, TMCDB::MCtestDevIO< T >, TMCDB::MCtestDevIOSeq< T >, TMCDB::MCtestDevIONoIncremental< T >, TMCDB::MCtestDevIOSeqNoIncremental< T >, TMCDB::MCtestDevIO< double >, and TMCDB::MCtestDevIOSeq< ACS::doubleSeq >.

template<class T>

virtual void DevIO< T >::write	(	const T &	value,
		ACS::Time &	timestamp
	)			`[inline, virtual]`

Method to write a value. It has to be override by implementation of DevIO If the method is not overriden, and it is called than ACSErrTypeCommon::NotImplementedExImpl exception is thrown!

Parameters:
