Class BasicAbstractConnectionPool

java.lang.Object
  org.firebirdsql.ds.RootCommonDataSource
      org.firebirdsql.pool.AbstractConnectionPool
          org.firebirdsql.pool.BasicAbstractConnectionPool

All Implemented Interfaces:

java.io.Serializable, javax.naming.Referenceable, javax.sql.CommonDataSource, javax.sql.ConnectionPoolDataSource, ConnectionPoolConfiguration, PooledObjectListener

Direct Known Subclasses:

AbstractDriverConnectionPoolDataSource, AbstractFBConnectionPoolDataSource

Deprecated.

@Deprecated
public abstract class BasicAbstractConnectionPool
extends AbstractConnectionPool
implements ConnectionPoolConfiguration, javax.sql.ConnectionPoolDataSource, java.io.Serializable, javax.naming.Referenceable

Base class for connection pool implementations. Main feature of this class is that it implements ConnectionPoolConfiguration interface and releives developers from creating getters and setters for pool configuration parameters. Additionally this class provides basic functionality for JNDI-enabled connection pools. No other functionality is available.

true if this pool supports pingable connections.

isPooling

public boolean isPooling()

Deprecated.

Description copied from interface: ConnectionPoolConfiguration

Check if this connection pool uses connection pooling, or just implements JDBC 2.0 SE interfaces. By default pooling is on. It might make sense to set pooling off to check performance degradation in test environment.

Deprecated.

isStatementPooling

public boolean isStatementPooling()

Check if this connection pool provides also prepared statement pooling. By default prepared statement pooling is enabled, however there might be situations where statement pooling is not desired, for example in environments where database can quickly run out of handles and fast handle reuse is required.

Specified by:

isStatementPooling in interface ConnectionPoolConfiguration

Returns:

true if prepared statement pooling is enabled.

setStatementPooling

public void setStatementPooling(boolean statementPooling)

Deprecated.

isKeepStatements

public boolean isKeepStatements()
