Constructor Detail

OracleJDBC_10_1_0_2ProxyConnectionCustomizer

public OracleJDBC_10_1_0_2ProxyConnectionCustomizer(org.eclipse.persistence.internal.databaseaccess.Accessor accessor,
                                                    Session session)

INTERNAL: Should be instantiated only if session.getProperty(PersistenceUnitProperties.ORACLE_PROXY_TYPE) != null.

Method Detail

customize

public void customize()

INTERNAL: Applies customization to connection. Called only if connection is not already customized (isActive()==false). The method may throw SQLException wrapped into DatabaseException. isActive method called after this method should return true only in case the connection was actually customized.

Specified by:

customize in class org.eclipse.persistence.internal.databaseaccess.ConnectionCustomizer

isActive

public boolean isActive()

INTERNAL: Indicated whether the connection is currently customized.

Specified by:

isActive in class org.eclipse.persistence.internal.databaseaccess.ConnectionCustomizer

clear

public void clear()

INTERNAL: Clears customization from connection. Called only if connection is customized (isActive()==true). If the method fails due to SQLException it should "eat" it (just like DatasourceAccessor.closeConnection method). isActive method called after this method should always return false.

Specified by:

clear in class org.eclipse.persistence.internal.databaseaccess.ConnectionCustomizer

clone

public java.lang.Object clone()

INTERNAL: Normally called only when customizer is in inactive state (isActive()==false) and followed by setAccessor call on the clone.

Overrides:

clone in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

INTERNAL: Two customizers considered equal if they produce the sane customization.

Overrides:

equals in class java.lang.Object

equals

public boolean equals(OracleJDBC_10_1_0_2ProxyConnectionCustomizer customizer)

INTERNAL: Two customizers considered equal if they produce the sane customization.

buildProxyProperties

protected void buildProxyProperties()

INTERNAL: Precondition: session.getProperty(PersistenceUnitProperties.ORACLE_PROXY_TYPE) != null

clearConnectionCache

protected void clearConnectionCache()

INTERNAL: Clears connection's both implicit and explicit caches.
