Other classes extend this abstract class to make connection to actual data sources. Method Summary abstract protected  void destroy()      Tells the connection provider to destroy itself. public  String getAuthor()      Returns the author of the connection provider. abstract public  Connection getConnection()      Returns a database connection. public  String getDescription()      Returns a description of the connection provider. public  int getMajorVersion()      Returns the major version of the connection provider, i.e. public  int getMinorVersion()      Returns the minor version of the connection provider, i.e. public  String getName()      Returns the name of the connection provider. abstract public  String getProperty(String name)      Returns the value of a property of the connection provider. Parameters:   name - the name of the property. abstract public  String getPropertyDescription(String name)      Returns the description of a property of the connection provider. Parameters:   name - the name of the property. public  boolean isPooled()      Returns true if this connection provider provides connections out of a connection pool. abstract public  Enumeration propertyNames()      Returns an enumeration of the property names for the connection provider. abstract protected  void restart()      This method should be called whenever properties have been changed so that the changes will take effect. abstract public  void setProperty(String name, String value)      Sets a property of the connection provider. abstract protected  void start()      Starts the connection provider. Method Detail destroy abstract protected void destroy()(Code) Tells the connection provider to destroy itself. For many connection providers, this will essentially result in a no-op. However, connection provider users should always call this method when changing from one connection provider to another to ensure that there are no dangling database connections. getAuthor public String getAuthor()(Code) Returns the author of the connection provider. the name of the author of this connection provider. getConnection abstract public Connection getConnection()(Code) Returns a database connection. When a Yazd component is done with a connection, it will call the close method of that connection. Therefore, connection pools with special release methods are not directly supported by the connection provider infrastructure. Instead, connections from those pools should be wrapped such that calling the close method on the wrapper class will release the connection from the pool. a Connection object. getDescription public String getDescription()(Code) Returns a description of the connection provider. the description of the connection provider. getMajorVersion public int getMajorVersion()(Code) Returns the major version of the connection provider, i.e. 1.x. the major version number of the provider. getMinorVersion public int getMinorVersion()(Code) Returns the minor version of the connection provider, i.e. x.1. the minor version number of the provider. getName public String getName()(Code) Returns the name of the connection provider. the name of the connection provider. getProperty abstract public String getProperty(String name)(Code) Returns the value of a property of the connection provider. Parameters:   name - the name of the property. the value of the property. getPropertyDescription abstract public String getPropertyDescription(String name)(Code) Returns the description of a property of the connection provider. Parameters:   name - the name of the property. the description of the property. isPooled public boolean isPooled()(Code) Returns true if this connection provider provides connections out of a connection pool. Implementing and using connection providers that are pooled is strongly recommended, as they greatly increase the speed of Yazd. true if the Connection objects returned by this provider arepooled. propertyNames abstract public Enumeration propertyNames()(Code) Returns an enumeration of the property names for the connection provider. an Enumeration of the property names. restart abstract protected void restart()(Code) This method should be called whenever properties have been changed so that the changes will take effect. setProperty abstract public void setProperty(String name, String value)(Code) Sets a property of the connection provider. Each provider has a set number of properties that are determined by the author. Trying to set a non- existant property will result in an IllegalArgumentException. Parameters:   name - the name of the property to set. Parameters:   value - the new value for the property. start abstract protected void start()(Code) Starts the connection provider. For some connection providers, this will be a no-op. However, connection provider users should always call this method to make sure the connection provider is started.
