Field Detail

DYNAMIC_MTP_STATE_VARIABLE

static final java.lang.String DYNAMIC_MTP_STATE_VARIABLE

This constant defines state variable name to be used for defining dynamic metatype of the control unit instance, this state variable belongs to. If the control unit interface declares a state variable with this name, the management applications will consider its value as pid of the metatype dynamically defining interface for this control unit instance. For control units that give null as value of this state variable, the applications should use the general metatype provided for the control unit type. GUI Application should hide this state variable from the control unit views, since it is considered to bring only visualization information to the GUI applications.
