Class OjbConfiguration

java.lang.Object
  org.apache.ojb.broker.util.configuration.impl.ConfigurationAbstractImpl
      org.apache.ojb.broker.util.configuration.impl.OjbConfiguration

All Implemented Interfaces:

Configuration, LockingConfiguration, LoggingConfiguration, MetadataConfiguration, OdmgConfiguration, PBPoolConfiguration, PersistenceBrokerConfiguration

public class OjbConfiguration

extends ConfigurationAbstractImpl

implements LoggingConfiguration, OdmgConfiguration, LockingConfiguration, PersistenceBrokerConfiguration, PBPoolConfiguration, MetadataConfiguration

This class contains the runtime configuration of the OJB system. This Configuration is read in only once at application startup. Changes to the OJB.properties file during execution are not reflected back into the application!

OjbConfiguration

public OjbConfiguration()

Method Detail

useSerializedRepository

public boolean useSerializedRepository()

Description copied from interface: MetadataConfiguration

If true OJB use a serialized version of the repository configuration file for repetition read.

Specified by:

useSerializedRepository in interface MetadataConfiguration

lockAssociationAsWrites

public boolean lockAssociationAsWrites()

Description copied from interface: OdmgConfiguration

If true acquiring a write-lock on a given object x implies write locks on all objects associated to x. If false implicit read-locks are acquired.

Specified by:

lockAssociationAsWrites in interface OdmgConfiguration

getRepositoryFilename

public java.lang.String getRepositoryFilename()

Specified by:

getRepositoryFilename in interface PersistenceBrokerConfiguration

getLoggerConfigFile

public java.lang.String getLoggerConfigFile()

Specified by:

getLoggerConfigFile in interface LoggingConfiguration

getLogLevel

public java.lang.String getLogLevel(java.lang.String loggerName)

Specified by:

getLogLevel in interface LoggingConfiguration

getMaxActive

public int getMaxActive()

Specified by:

getMaxActive in interface PBPoolConfiguration

getMaxIdle

public int getMaxIdle()

Specified by:

getMaxIdle in interface PBPoolConfiguration

getMaxWaitMillis

public long getMaxWaitMillis()

Specified by:

getMaxWaitMillis in interface PBPoolConfiguration

getTimeBetweenEvictionRunsMilli

public long getTimeBetweenEvictionRunsMilli()

Specified by:

getTimeBetweenEvictionRunsMilli in interface PBPoolConfiguration

getMinEvictableIdleTimeMillis

public long getMinEvictableIdleTimeMillis()

Specified by:

getMinEvictableIdleTimeMillis in interface PBPoolConfiguration

getWhenExhaustedAction

public byte getWhenExhaustedAction()

Specified by:

getWhenExhaustedAction in interface PBPoolConfiguration

getObjectCacheClass

public java.lang.Class getObjectCacheClass()

Specified by:

getObjectCacheClass in interface PersistenceBrokerConfiguration

getCacheFilters

public java.lang.String[] getCacheFilters()

Description copied from interface: PersistenceBrokerConfiguration

Returns an array of the declared CacheFilter, or null if none found.

Specified by:

getCacheFilters in interface PersistenceBrokerConfiguration

setCacheFilters

public void setCacheFilters(java.lang.String[] filters)

Useful when writing test cases

getConnectionFactoryClass

public java.lang.Class getConnectionFactoryClass()

Specified by:

getConnectionFactoryClass in interface PersistenceBrokerConfiguration

getLockManagerClass

public java.lang.Class getLockManagerClass()

Specified by:

getLockManagerClass in interface LockingConfiguration

getOqlCollectionClass

public java.lang.Class getOqlCollectionClass()

Description copied from interface: OdmgConfiguration

This class is used to hold results of OQL queries. By default a DListImpl is used.

Specified by:

getOqlCollectionClass in interface OdmgConfiguration

getLockMapClass

public java.lang.Class getLockMapClass()

getLoggerClass in interface LoggingConfiguration

getPersistentFieldClass

public java.lang.Class getPersistentFieldClass()

Specified by:

getPersistentFieldClass in interface PersistenceBrokerConfiguration

getPersistenceBrokerClass

public java.lang.Class getPersistenceBrokerClass()

Specified by:

getPersistenceBrokerClass in interface PersistenceBrokerConfiguration

load

protected void load()

loads the configuration from file "OBJ.properties". If the system property "OJB.properties" is set, then the configuration in that file is loaded.

Overrides:

load in class ConfigurationAbstractImpl

See Also:

ConfigurationAbstractImpl.setFilename(java.lang.String)

getSqlInLimit

public int getSqlInLimit()

Returns the SQLInLimit.

Specified by:

getSqlInLimit in interface PersistenceBrokerConfiguration

Returns:

int

setPersistentFieldClass

public void setPersistentFieldClass(java.lang.Class persistentFieldClass)

Sets the persistentFieldClass.

Parameters:

persistentFieldClass - The persistentFieldClass to set

useImplicitLocking

public boolean useImplicitLocking()

Description copied from interface: OdmgConfiguration

defines if implicit lock acquisition is to be used. If set to true OJB implicitely locks objects to ODMG transactions after performing OQL queries. If implicit locking is used locking objects is recursive, that is associated objects are also locked. If ImplicitLocking is set to false, no locks are obtained in OQL queries and there is also no recursive locking.

Specified by:

useImplicitLocking in interface OdmgConfiguration

See Also:

OdmgConfiguration.useImplicitLocking()

setUseImplicitLocking

public void setUseImplicitLocking(boolean implicitLocking)

getCollectionProxyClass

public java.lang.Class getCollectionProxyClass()

Description copied from interface: PersistenceBrokerConfiguration

Answer the class to be used for CollectionProxy

Specified by:

getCollectionProxyClass in interface PersistenceBrokerConfiguration

Returns:

Class

See Also:

PersistenceBrokerConfiguration.getCollectionProxyClass()
