Function Documentation

◆ get_connection()

AbstractConnection ConnectionProvider::get_connection ( string conn )

returns an AbstractConnection object if the identifier is known to a registered connection provider

Example:: string connstr = get_connection(str);

Parameters

conn	the connection identifier

Returns: the connection object

Exceptions

CONNECTION-ERROR the connection string cannot be matched as an external url identifier by a connection provider module

Note: connection provider modules are processed in the order they are declared with the QORE_CONNECTION_PROVIDERS environment variable; connection provider modules must be separated with PathSep characters

See also: Connection Provider Modules

◆ get_connection_hash()

*hash< string, hash< ConnectionInfo > > ConnectionProvider::get_connection_hash ( *bool verbose )

returns a hash of connection information keyed by connection identifier; values are ConnectionInfo hashes as returned by AbstractConnection::getInfo() (with passwords included)

Example:: *hash<string, hash<ConnectionInfo>> h = get_connection_hash();

Parameters

verbose display connection provider module errors on stdout (otherwise errors are silently ignored)

Returns: a hash keyed by connection identifier; values are ConnectionInfo hashes as returned by AbstractConnection::getInfo() (with passwords included); NOTHING is returned if no connections are known

Note: connection provider modules are processed in the order they are declared with the QORE_CONNECTION_PROVIDERS environment variable; connection provider modules must be separated with PathSep characters

See also

◆ get_connection_url()

string ConnectionProvider::get_connection_url ( string str )

returns a URL string for the given identifier if the identifier is known to a registered connection provider or returns the URL itself if the identifier is a valid URL

Example:: string connstr = get_connection_url(str);

Parameters

str	the connection identifier or a valid URL connection string (a URL string is considered valid for this function if it begins with a scheme and has at least one character after the scheme; ex: `"scheme://x..."`

Returns: the URL string corresponding to the connection identifier, or, in case the argument is a valid URL string, returns the argument itself

Exceptions

CONNECTION-ERROR the connection string cannot be matched as an external url identifier by a connection provider module and there is no scheme (i.e. protocol) specification in the string followed by at least one character (ex: "scheme://x...")

Note: connection provider modules are processed in the order they are declared with the QORE_CONNECTION_PROVIDERS environment variable; connection provider modules must be separated with PathSep characters

See also: Connection Provider Modules

◆ get_connections()

*hash< string, AbstractConnection > ConnectionProvider::get_connections ( *bool verbose )

returns all known connections as a hash keyed by connection identifier; values are AbstractConnection objects; NOTHING is returned if no connections are known

Example:: *hash<string, AbstractConnection> h = get_connections();

Parameters

verbose display connection provider module errors on stdout (otherwise errors are ignored)

Returns: a hash keyed by connection identifier; values are AbstractConnection objects; NOTHING is returned if no connections are known

Note: connection provider modules are processed in the order they are declared with the QORE_CONNECTION_PROVIDERS environment variable; connection provider modules must be separated with PathSep characters
