Definition at line 131 of file configuration.h.

getPropertyAsAddress()

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

name	name of the environment variable to return. @pram addr pointer to the address struct to be filled in

Returns

true if addr now contains an address, false otherwise

getPropertyAsBoolean()

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

name	name of the environment variable to return.
defualtValue	default value to return if environment variable does not exists.

Returns

environment variable value as bool or default value if it does not exist.

getPropertyAsDouble()

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

name	name of the environment variable to return.
defualtValue	default value to return if environment variable does not exists.

Returns

environment variable value as double or default value if it does not exist.

getPropertyAsFloat()

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

name	name of the environment variable to return.
defualtValue	default value to return if environment variable does not exists.

Returns

environment variable value as float or default value if it does not exist.

getPropertyAsInteger()

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

name	name of the environment variable to return.
defualtValue	default value to return if environment variable does not exists.

Returns

environment variable value as int32 or default value if it does not exist.

getPropertyAsString()

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

name	name of the environment variable to return.
defualtValue	default 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()

keys_t epics::pvAccess::Configuration::keys ( ) const

inlineinherited

Return a (partial) list of available key names.

Does not include key names from the ConfigurationEnviron
