Field Summary

Fields

Modifier and Type	Field and Description
static String	ARCHIVE_FACTORY Configures the factory class we use to produce instances of org.eclispe.persistence.jpa.Archive These instances are used to examine persistence units and the files within them and are used for discovery of classes in the persistence unit Allows user-provided ArchiveFactory and Archive
static String	DO_NOT_PROCESS_XTOMANY_FOR_QBE This property can be set to disable processing of X-Many relationship attributes for Query By Example objects.
static String	ENFORCE_TARGET_SERVER This system property can be set to override target server platform set by the Java EE container with the one either set in persistence.xml or auto detected.
static String	ONETOMANY_DEFER_INSERTS This property can be set to false to enable UPDATE call to set foreign key value in the target row in unidirectional 1-Many mapping with not nullable FK.
static String	RECORD_STACK_ON_LOCK This property is used in conjunction with org.eclipse.persistence.sessions.IdentityMapAccessor.printIdentityMapLocks().
static String	WEAVING_OUTPUT_PATH This property is used to debug weaving issues.
static String	WEAVING_REFLECTIVE_INTROSPECTION This property can be used to tell EclipseLink to process classes in the ASM Default manner.
static String	WEAVING_SHOULD_OVERWRITE This property is used in conjunction with WEAVING_OUTPUT_PATH.

Field Detail

ARCHIVE_FACTORY

public static final String ARCHIVE_FACTORY

Configures the factory class we use to produce instances of org.eclispe.persistence.jpa.Archive These instances are used to examine persistence units and the files within them and are used for discovery of classes in the persistence unit Allows user-provided ArchiveFactory and Archive

Constant Field Values

WEAVING_OUTPUT_PATH

public static final String WEAVING_OUTPUT_PATH

This property is used to debug weaving issues. When it is set, weaved classes will be output to the given path as they are weaved

Constant Field Values

WEAVING_SHOULD_OVERWRITE

public static final String WEAVING_SHOULD_OVERWRITE

This property is used in conjunction with WEAVING_OUTPUT_PATH. By default, existing classes on the path provided to WEAVING_OUTPUT_PATH will not be overridden. If this is set to true, they will be

Constant Field Values

WEAVING_REFLECTIVE_INTROSPECTION

public static final String WEAVING_REFLECTIVE_INTROSPECTION

This property can be used to tell EclipseLink to process classes in the ASM Default manner. The fix for bug 370975 changes EclipseLink's weaving support to use ASM itself to examine class hierarchies. Setting this flag to true will cause us to use the default reflection mechanism again. This flag provides a means to workaround any issues encountered with the ASM-based weaving introspection

Constant Field Values

RECORD_STACK_ON_LOCK

public static final String RECORD_STACK_ON_LOCK

This property is used in conjunction with org.eclipse.persistence.sessions.IdentityMapAccessor.printIdentityMapLocks(). Setting this property will cause EclipseLink to record the stack trace of the lock acquisition and print it along with the identity map locks. This should only be set if the thread that owns a lock is not 'stuck' but still owns the lock when a normal printIdentityMapLocks is done. This can also be set in code statically through ConcurrencyManager.setShouldTrackStack(true)

Constant Field Values

DO_NOT_PROCESS_XTOMANY_FOR_QBE

public static final String DO_NOT_PROCESS_XTOMANY_FOR_QBE

This property can be set to disable processing of X-Many relationship attributes for Query By Example objects. In previous versions of EclipseLink these attributes would have been ignored but as of this release they will be processed into the expression.

Constant Field Values

ENFORCE_TARGET_SERVER

public static final String ENFORCE_TARGET_SERVER

This system property can be set to override target server platform set by the Java EE container with the one either set in persistence.xml or auto detected.

See Also:

Constant Field Values

ONETOMANY_DEFER_INSERTS

public static final String ONETOMANY_DEFER_INSERTS

This property can be set to false to enable UPDATE call to set foreign key value in the target row in unidirectional 1-Many mapping with not nullable FK. In previous versions of EclipseLink this was the default behaviour. Allowed values are: true/false.
