Detailed Description

A Plugin handles all connections related to a DBMS (Postgres, MySQL, and so on).

This class allows traversal of the list of available connections, and can be queried about general informations and implemented capabilities through provides

The Plugin is also responsible of creating "capability objects", that is objects that can implement a specific capabilities.

Actually we have found the following capabilities:

PluginInfo (struct)

 Plugin (QObject *parent = 0L, const char *name = 0L)

 ~Plugin ()

[virtual]

PluginInfo  info ()

[pure virtual]

Returns the information about the plugin.

Connection *  openConnection (const QString &host, int port = 0, const QString &user = QString::null, const QString &password = QString::null)

Create a connection, append it to the connection list, open the connection and return it.

Connection *  addConnection (const QString &host, int port = 0, const QString &user = QString::null, const QString &password = QString::null)

[virtual]

Same as connect, but does not perform the connection.

void  remove (Connection *)

Removes a connection from the list of connections. This will delete the connection, so make sure to not have dangling reference to the connection.

Connection *  findConnection (const QString &host, const QString & user)

Return a connection to the specified host for the given user. If no connection is found 0L is returned.

ConnectionIterator  begin ()

Returns an iterator that points to the first Connection object.

bool  provides (capability cap)

[pure virtual]

returns true if the plugin can handle a given capability.

Capability *  createObject (capability cap)

[pure virtual]

Create an object that will handle the specific capability if the plugin does not support a capability, an exception is thrown.
