Method Detail

refDelegate

Object_1_0 refDelegate()

Return the object which RefObject_1_0 delegates to. The returned object is managed by a basic accessor.

Returns:

Object_1_0 delegate object.

refGetPath

Path refGetPath()

Returns the object's access path.

Returns:

the object's access path; or null for transient objects

refWriteProtect

void refWriteProtect()

Puts an object in read-only mode.

This method is idempotent.

Throws:

JmiServiceException - ILLEGAL_STATE if the object is dirty

refAddToUnitOfWork

void refAddToUnitOfWork()

After this call the object observes unit of work boundaries.

This method is idempotent.

Throws:

JmiServiceException - ILLEGAL_STATE if the object is locked

JmiServiceException - if the object can't be added to the unit of work for another reason.

refRemoveFromUnitOfWork

void refRemoveFromUnitOfWork()

After this call the object ignores unit of work boundaries.

This method is idempotent.

Throws:

JmiServiceException - ILLEGAL_STATE if the object is dirty.

JmiServiceException - if the object can't be removed from its unit of work for another reason

refIsWriteProtected

boolean refIsWriteProtected()

Tells whether this object is in read-only mode.

Returns:

true if the object is write protected, false if the object is write enabled.

refIsDirty

boolean refIsDirty()

Tests whether this object is dirty. Instances that have been modified, deleted, or newly made persistent in the current unit of work return true.

Transient instances return false.

Returns:

true if this instance has been modified in the current unit of work.

refIsPersistent

boolean refIsPersistent()

Tests whether this object is persistent. Instances that represent persistent objects in the data store return true.

Returns:

true if this instance is persistent.

refIsNew

boolean refIsNew()

Tests whether this object has been newly made persistent. Instances that have been made persistent in the current unit of work return true.

Transient instances return false.

Returns:

true if this instance was made persistent in the current unit of work.

refIsDeleted

boolean refIsDeleted()

Tests whether this object has been deleted. Instances that have been deleted in the current unit of work return true. Transient instances return false.

Returns:

true if this instance was deleted in the current unit of work.

refRefresh

void refRefresh()

Refresh the state of the instance from its provider.

Throws:

JmiServiceException - if the object can't be synchronized

refFlush

void refFlush()

Flush the state of the instance to its provider.

Throws:

JmiServiceException - if the object can't be flushed.

refRefreshAsynchronously

void refRefreshAsynchronously()

Refresh the state of the instance from its provider asynchrounously.

Throws:

JmiServiceException - if the object can't be synchronized asynchronously

refDefaultFetchGroup

Set<String> refDefaultFetchGroup()

Returns the refDelegate().objDefaultFetchGroup() plus the set of all non-derived attributes of the object.

refContext

Object refContext()

Returns application-defined context.

Returns:

Object application-defined context.

refInitialize

void refInitialize(RefObject source)

Initializes the object based on the source object. The source object must be of the same class or a subtype of the target.

Parameters:

existing - existing object.

Throws:

JmiServiceException - thrown if object can not be initialized.

refInitialize

void refInitialize(boolean setRequiredToNull,
                   boolean setOptionalToNull)

Initializes the object as follows:

• collections are cleared.
• primitive required attributes are set to default values: string = ""; number = 0; date = min date. They are set to null if setRequiredToNull==true.
• primitive optional attributes are set to null if initializeOptional == true and are left untouched if initializeOptional == false.
• required references can not be initialized and an exception is thrown.

Parameters:

setRequiredToNull - if true, required attributes are set to null. Otherwise they are initialized with a default value.

setOptionalToNull - if true, optional features are set to true, otherwise they are left untouched.

Throws:

JmiServiceException - thrown if object can not be initialized.

refGetValue

Object refGetValue(RefObject feature,
                   Object qualifier,
                   boolean marshal)

Returns the value of feature identified by qualifier. marshal defines whether marshalling is applied to the returned object. If false a RefObject which is in fact of type 'org:openmdx:test:app1:Partner' is returned as type RefObject instead of org.openmdx.test.app1.Partner. This method method can improve performance in cases where no marshalled objects are required.

Parameters:

feature - feature to be retrieved.

qualifier - identifies object to be retrieved.

marshal - if true the returned value is marshalled.

Throws:

JmiServiceException

refGetValue

long refGetValue(String feature,
                 Object value,
                 long position)

Returns the value of feature. Instead of returning the value as return value it is streamed to value. The value must either be a binary or character output stream.

Parameters:

feature - feature to be retrieved.

value - binary or character output stream.

position - stream is returned starting from position.

Returns:

length of the stream.

Throws:

JmiServiceException

refSetValue

void refSetValue(String feature,
                 Object newValue,
                 long length)

Sets the value of feature. The value must be a binary or character input stream of the specified length. The parameter length results in better performance for stream handling.

Parameters:

feature - feature to be retrieved.

newValue - binary or character input stream.

length - length of the stream.

Throws:

JmiServiceException

refAddValue

void refAddValue(String featureName,
                 Object qualifier,
                 Object value)

Adds the value to the feature with the specified qualifier.

Parameters:

featureName - feature to add value.

qualifier - qualifier of value to add.

value - value to add.

                    Object qualifier)

Removes qualified value from feature.

Parameters:

featureName - qualified value is removed from feature.

qualifier - value qualifier.

refRemoveValue

void refRemoveValue(String featureName,
                    RefObject value)

Removes value from feature.
