BasicObjectContext

public BasicObjectContext(Object objectId,
                          org.eclipse.emf.ecore.EClass eClass,
                          String segmentId,

                          Object computationCause,
                          long baseVersion)

Creates a new instance of the context

Parameters:

objectId - The identifier of the object (BM or language) this context corresponds to. May not be null

eClass - The EClass of the of the top BM object this context corresponds to. May not be null

segmentId - The identifier of DD segment this context belongs to. May not be null

computationCause - The identifier of the context collection session. May be null

baseVersion - The base version of the context for the operations of the context merge and conflict detection

Method Detail

getBaseVersion

public long getBaseVersion()

Description copied from interface: IObjectDerivedDataContext

Gets the base version of the context. The base version is used during the conflict resolution phase. In case if context computation task is started for the particular version, any updates of the context wiil result in cancelling of the computed results.

Specified by:

getBaseVersion in interface IObjectDerivedDataContext

Returns:

The base version of the context.

getObjectId

public Object getObjectId()

Description copied from interface: IObjectDerivedDataContext

Gets the the object the context belongs to.

Specified by:

getObjectId in interface IObjectDerivedDataContext

Returns:

The object, never null

getBmObjectId

public long getBmObjectId()

Description copied from interface: IObjectDerivedDataContext

Gets the identifier of the object the context belongs to.

Specified by:

getBmObjectId in interface IObjectDerivedDataContext

Returns:

The identifier of the object.

getComputationCause

public Object getComputationCause()

Description copied from interface: IObjectDerivedDataContext

Gets the identifier of the session the context is being collected for. Used only for sync contexts.

Specified by:

getComputationCause in interface IObjectDerivedDataContext

Returns:

The identifier of the session.

getEClass

public org.eclipse.emf.ecore.EClass getEClass()

Description copied from interface: IObjectDerivedDataContext

Gets the EClass of the target object.

Specified by:

getEClass in interface IObjectDerivedDataContext

Returns:

The target object EClass.

getSegmentId

public String getSegmentId()

Description copied from interface: IObjectDerivedDataContext

Gets the derived data segment identifier this context is collected for.

Specified by:

getSegmentId in interface IObjectDerivedDataContext

Returns:

The unique identifier of the DD segment.

getTransactionHandle

public Object getTransactionHandle()

Description copied from interface: IObjectDerivedDataContext

Gets the associated transaction handle (if any).

Specified by:

getTransactionHandle in interface IObjectDerivedDataContext

Returns:

The associated transaction handle (if any). null otherwise.

getVersion

public long getVersion()

Description copied from interface: IObjectDerivedDataContext

Gets the current version of the context. The version is defined during the snapshotting of the context. The verison is used during the context merge process to update the base version.

Specified by:

getVersion in interface IObjectDerivedDataContext

Returns:

The version of the context.

isFullRebuild

public boolean isFullRebuild()

Description copied from interface: IObjectDerivedDataContext

Checks if the full rebuild mode is set for the object.

Specified by:

isFullRebuild in interface IObjectDerivedDataContext

Returns:

True if the full rebuild is required for the given top object.

isRemoval

public boolean isRemoval()

Description copied from interface: IObjectDerivedDataContext

Checks if the current context represents removed object.

Specified by:

isRemoval in interface IObjectDerivedDataContext

Returns:

True if the context was collected for the removed object; false otherwise.

setBaseVersion

public void setBaseVersion(long version)

Description copied from interface: IObjectDerivedDataContext

Sets the base version of the context. Used during the merge operation.

Specified by:

setBaseVersion in interface IObjectDerivedDataContext

Parameters:

version - The version to set.

setFullRebuild

public void setFullRebuild(boolean fullRebuild)

Description copied from interface: IObjectDerivedDataContext

Sets/resets the full rebuild designator for the context object DD.

Specified by:

setFullRebuild in interface IObjectDerivedDataContext

Parameters:

fullRebuild - Full rebuild flag.

setTransactionHandle

public void setTransactionHandle(Object transactionHandle)

Description copied from interface: IObjectDerivedDataContext

Sets the transaction handle for this context.

Specified by:

setTransactionHandle in interface IObjectDerivedDataContext
