Method Detail

getStrictIdentityValues

public boolean getStrictIdentityValues()

Whether to require exact identity value types when creating object ids from a class and value. Defaults to false.

setStrictIdentityValues

public void setStrictIdentityValues(boolean strictVals)

Whether to require exact identity value types when creating object ids from a class and value. Defaults to false.

getQuotedNumbersInQueries

public boolean getQuotedNumbersInQueries()

Whether to interpret quoted numbers in query strings as numbers. OpenJPA versions 0.3.1 and prior treated them as numbers; more recent versions treat them as strings.

setQuotedNumbersInQueries

public void setQuotedNumbersInQueries(boolean quotedNumbers)

Whether to interpret quoted numbers in query strings as numbers. OpenJPA versions 0.3.1 and prior treated them as numbers; more recent versions treat them as strings.

getValidateFalseReturnsHollow

public boolean getValidateFalseReturnsHollow()

Whether to return hollow instances to broker lookups with a validate parameter of false. OpenJPA versions prior to 0.4.0 did not return hollow instances without special configuration (the ObjectLookupMode). Beginning with 0.4.0, hollow objects are the default.

setValidateFalseReturnsHollow

public void setValidateFalseReturnsHollow(boolean hollow)

Whether to return hollow instances to broker lookups with a validate parameter of false. OpenJPA versions prior to 0.4.0 did not return hollow instances without special configuration (the ObjectLookupMode). Beginning with 0.4.0, hollow objects are the default.

getValidateTrueChecksStore

public boolean getValidateTrueChecksStore()

Whether to check the datastore for the existence of a nontransactional cached object in broker lookups with a validate parameter of true. OpenJPA versions prior to 0.4.0 checked the datastore.

setValidateTrueChecksStore

public void setValidateTrueChecksStore(boolean check)

Whether to check the datastore for the existence of a nontransactional cached object in broker lookups with a validate parameter of true. OpenJPA versions prior to 0.4.0 checked the datastore.

getCopyObjectIds

public boolean getCopyObjectIds()

Whether to copy identity objects before returning them to client code. Versions of OpenJPA prior to 0.3.0 always copied identity objects. Also, you should configure OpenJPA to copy identity objects if you mutate them after use.

setCopyObjectIds

public void setCopyObjectIds(boolean copy)

Whether to copy identity objects before returning them to client code. Versions of OpenJPA prior to 0.3.0 always copied identity objects. Also, you should configure OpenJPA to copy identity objects if you mutate them after use.

getCloseOnManagedCommit

public boolean getCloseOnManagedCommit()

Whether to close the broker when the managed transaction commits. Versions of OpenJPA prior to 0.3.0 did not close the broker.

setCloseOnManagedCommit

public void setCloseOnManagedCommit(boolean close)

Whether to close the broker when the managed transaction commits. Versions of OpenJPA prior to 0.3.0 did not close the broker.

setNonOptimisticVersionCheck

public void setNonOptimisticVersionCheck(boolean nonOptimisticVersionCheck)

Whether or not to perform a version check on instances being updated in a datastore transaction. Version of OpenJPA prior to 0.4.1 always forced a version check.

getNonOptimisticVersionCheck

public boolean getNonOptimisticVersionCheck()

Whether or not to perform a version check on instances being updated in a datastore transaction. Version of OpenJPA prior to 0.4.1 always forced a version check.

getJPQL

public int getJPQL()

Whether or not JPQL extensions are allowed. Defaults to JPQL_STRICT.

Since:

1.1.0

See Also:

JPQL_WARN, JPQL_STRICT, JPQL_EXTENDED

setJPQL

public void setJPQL(String jpql)

Whether or not JPQL extensions are allowed. Possible values: "warn", "strict", "extended".

Since:

1.1.0

See Also:

JPQL_WARN, JPQL_STRICT, JPQL_EXTENDED

getStoreMapCollectionInEntityAsBlob

public boolean getStoreMapCollectionInEntityAsBlob()

Whether if map and collection in entity are stored as blob. Defaults to false.

Since:

1.1.0

setStoreMapCollectionInEntityAsBlob

public void setStoreMapCollectionInEntityAsBlob(boolean storeAsBlob)

Whether if map and collection in entity are stored as blob. Defaults to false.

Since:

1.1.0

getFlushBeforeDetach

public boolean getFlushBeforeDetach()

Whether OpenJPA should flush changes before detaching or serializing an entity. In JPA this is usually false, but other persistence frameworks (ie JDO) may expect it to be true.

Prior to version 1.0.3 and 1.2.0 changes were always flushed.

Returns:

true if changes should be flushed, otherwise false.

Since:

1.0.3, 1.2.0

setFlushBeforeDetach

public void setFlushBeforeDetach(boolean beforeDetach)

Whether OpenJPA should flush changes before detaching or serializing an entity. In JPA this is usually false, but other persistence frameworks (ie JDO) may expect it to be true.

Prior to version 1.0.3 and 1.2.0 changes were always flushed.

Parameters:

beforeDetach - if true changes will be flushed before detaching or serializing an entity.

Since:

1.0.3, 1.2.0

getReorderMetaDataResolution

public boolean getReorderMetaDataResolution()

Whether OpenJPA should reorder entities in MetaDataRepository.processBuffer() to ensure that the MetaData for entities with foreign keys in their identity are processed after the entities they depend on.

Returns:

true if the reordering should be performed, false if not.

setReorderMetaDataResolution

public void setReorderMetaDataResolution(boolean reorderProcessBuffer)

Whether OpenJPA should reorder entities in MetaDataRepository.processBuffer() to ensure that the MetaData for entities with foreign keys in their identity are processed after the entities they depend on.

Parameters:

reorderProcessBuffer - true if the reordering should be performed, false if not.

getReloadOnDetach

public boolean getReloadOnDetach()

Whether OpenJPA should attempt to load fields when the DetachState option is set to loaded. This also determines whether a redundant copy of the version field is made. Defaults to true.

Returns:

the _reloadOnDetach

Since:

1.2.2

setReloadOnDetach

public void setReloadOnDetach(boolean reloadOnDetach)

Whether OpenJPA should attempt to load fields when the DetachState option is set to loaded. This also determines whether a redundant copy of the version field is made. Defaults to true.

Parameters:

reloadOnDetach - the _reloadOnDetach to set

Since:

1.2.2
