Detailed Description

A high level object for a device interface to the database.

A database object for a device which can be used to query or modify properties, import and export information for a device. This class provides an easy to use interface for device objects in the database. It uses the methods of the Database class therefore the reader is referred to these for the exact calling syntax and examples. The following methods are defined for the DbDevice class :

Constructor & Destructor Documentation

◆ DbDevice() [1/2]

DbDevice::DbDevice ( string & dev_name )

Create a DbDevice object.

A constructor for a DbDevice object for a device in the TANGO database specified by the TANGO_HOST environment variable.

Parameters

[in] dev_name The device name

◆ DbDevice() [2/2]

DbDevice::DbDevice	(	string &	dev_name,
		Database *	db
	)
