public class JDBCCacheLoaderOld
extends AdjListJDBCCacheLoader

JDBC CacheLoader implementation.

This implementation uses one table. The table consists of three columns:

• text column for fqn (which is also a primary key)
• blob column for attributes (can contain null)
• text column for parent fqn (can contain null)

The configuration options are:

Table configuration

• cache.jdbc.table.name - the table name (default is jbosscache)
• cache.jdbc.table.create - should be true or false, indicates whether to create the table at start phase
• cache.jdbc.table.drop - should be true or false, indicates whether to drop the table at stop phase
• cache.jdbc.table.primarykey - the name for the table primary key (default is jbosscache_pk)
• cache.jdbc.fqn.column - the name for the fqn column (default is fqn)
• cache.jdbc.fqn.type - the type for the fqn column (default is varchar(255))
• cache.jdbc.node.column - the name for the node's contents column (default is node)
• cache.jdbc.node.type - the type for the node's contents column (default is blob)
• cache.jdbc.parent.column - the name for the parent fqn column (default is parent)

DataSource configuration

• cache.jdbc.datasource - the JNDI name of the datasource

JDBC driver configuration (used when DataSource is not configured)

• cache.jdbc.driver - fully qualified JDBC driver name
• cache.jdbc.url - URL to connect to the database
• cache.jdbc.user - the username to use to connect to the database
• cache.jdbc.password - the password to use to connect to the database

getConfig

public CacheLoaderConfig.IndividualCacheLoaderConfig getConfig()

Deprecated.

Description copied from interface: CacheLoader

Gets the configuration.

Returns:

the configuration, represented by a CacheLoaderConfig.IndividualCacheLoaderConfig object.

put

public Object put(Fqn name,
                  Object key,
                  Object value)
           throws Exception

Deprecated.

Adds/overrides a value in a node for a key. If the node does not exist yet, the node will be created. If parent nodes do not exist for the node, empty parent nodes will be created.

Parameters:

name - node's fqn

key - attribute's key

value - attribute's value

Returns:

old value associated with the attribute's key or null if there was no value previously associated with the attribute's key

Throws:

Exception

put

public void put(Fqn name,
                Map attributes)
         throws Exception

Deprecated.

Adds attributes from the passed in map to the existing node. If there is no node for the fqn, a new node will be created.

Parameters:

name - node's fqn

attributes - attributes

Throws:

Exception

remove

            throws Exception

Deprecated.

Removes a node and all its children. Uses the same connection for all the db work.

Parameters:

name - node's fqn

Throws:

Exception
