Member Function Documentation

bool epics::pvAccess::Configuration::getPropertyAsAddress ( const std::string name,
osiSockAddr *  addr 
) const
inherited

Fetch and parse as a socket address and port number (address family set accordingly).

At present only numeric addresses are parsed (eg. "127.0.0.1:4242").

The storage pointed to be addr should be initialized with a default value, or zeroed.

Parameters
namename of the environment variable to return. addr pointer to the address struct to be filled in
Returns
true if addr now contains an address, false otherwise
bool epics::pvAccess::Configuration::getPropertyAsBoolean ( const std::string name,
const bool  defaultValue 
) const
inherited

Get the environment variable specified by name or return default value if it does not exist.

Parameters
namename of the environment variable to return.
defualtValuedefault value to return if environment variable does not exists.
Returns
environment variable value as bool or default value if it does not exist.
double epics::pvAccess::Configuration::getPropertyAsDouble ( const std::string name,
const double  defaultValue 
) const
inherited

Get the environment variable specified by name or return default value if it does not exist.

Parameters
namename of the environment variable to return.
defualtValuedefault value to return if environment variable does not exists.
Returns
environment variable value as double or default value if it does not exist.
float epics::pvAccess::Configuration::getPropertyAsFloat ( const std::string name,
const float  defaultValue 
) const
inherited

Get the environment variable specified by name or return default value if it does not exist.

Parameters
namename of the environment variable to return.
defualtValuedefault value to return if environment variable does not exists.
Returns
environment variable value as float or default value if it does not exist.
epics::pvData::int32 epics::pvAccess::Configuration::getPropertyAsInteger ( const std::string name,
const epics::pvData::int32  defaultValue 
) const
inherited

Get the environment variable specified by name or return default value if it does not exist.

Parameters
namename of the environment variable to return.
defualtValuedefault value to return if environment variable does not exists.
Returns
environment variable value as int32 or default value if it does not exist.
std::string epics::pvAccess::Configuration::getPropertyAsString ( const std::string name,
const std::string defaultValue 
) const
inherited

Get the environment variable specified by name or return default value if it does not exist.

Parameters
namename of the environment variable to return.
defualtValuedefault value to return if environment variable does not exists.
Returns
environment variable value as std::string or default value if it does not exist.
keys_t epics::pvAccess::Configuration::keys ( ) const
inlineinherited

Return a (partial) list of available key names.

Does not include key names from the ConfigurationEnviron
