GetRandomBits()

uint32_t StationScopeResolver::GetRandomBits ( ) const

overridevirtual

Get a few random bits.

Default implementation has no random bits.

Returns

Random bits.

GetRandomTriggers()

uint32_t StationScopeResolver::GetRandomTriggers ( ) const

overridevirtual

Get the triggers.

Base class returns 0 to prevent trouble.

Returns

GetVariable()

uint32_t StationScopeResolver::GetVariable ( uint8_t  variable, uint32_t  parameter, bool &  available  ) const

overridevirtual

Get a variable value.

Default implementation has no available variables.

Parameters

	variable	Variable to read
	parameter	Parameter for 60+x variables
[out]	available	Set to false, in case the variable does not exist.

Returns

Value
