Field Detail

numRefs

public int numRefs

Number of references pointing to instance.

Constructor Detail

DataClayExecutionObject

public DataClayExecutionObject()

Basic constructor

DataClayExecutionObject

public DataClayExecutionObject(ObjectID theobjectID)

Constructor

Parameters:

theobjectID - ID of the object

Method Detail

initializeObjectAsPersistent

public void initializeObjectAsPersistent()

Initialize object with state 'persistent' with proper flags. See same function in DataClayExecutionObject for a different initialization. This design is intended to be clear with object state. Usually, since constructors are calling initializeObjectAsVolatile, this function 'overrides' flags set

Overrides:

initializeObjectAsPersistent in class DataClayObject

initializeObjectAsVolatile

public void initializeObjectAsVolatile()

Initialize object with state 'volatile' with proper flags. Usually, volatile state is created by a stub, app, exec class,.. See same function in DataClayExecutionObject for a different initialization. This design is intended to be clear with object state.

Overrides:

initializeObjectAsVolatile in class DataClayObject

setAsDirty

public void setAsDirty()

Set dirty flag to true

isDirty

public boolean isDirty()

Get dirty flag

Returns:

TRUE if object is dirty. False otherwise.

setDirty

public void setDirty(boolean thedirtyValue)

Set dirty flag

Parameters:

thedirtyValue - dirty flag value

isLoaded

public final boolean isLoaded()

Get the DataClayObject::isLoaded

Returns:

the isLoaded

getOwnerSessionIDforVolatiles

public SessionID getOwnerSessionIDforVolatiles()

Returns:

the ownerSessionIDforVolatiles

setOwnerSessionIDforVolatiles

public void setOwnerSessionIDforVolatiles(SessionID newownerSessionIDforVolatiles)

Parameters:

newownerSessionIDforVolatiles - the ownerSessionIDforVolatiles to set

setDataSetID

public void setDataSetID(DataSetID newDataSetID)

Description copied from class: DataClayObject

Set object DataSetID

Overrides:

setDataSetID in class DataClayObject

Parameters:

newDataSetID - ID of DataSet this object belongs to

getCreationTimeStamp

public long getCreationTimeStamp()

Returns:

the creationTimeStamp

setCreationTimeStamp

public void setCreationTimeStamp(long thecreationTimeStamp)

Parameters:

thecreationTimeStamp - the creationTimeStamp to set

setNumRefs

public void setNumRefs(int thenumRefs)

Parameters:

thenumRefs - the numRefs to set

isPendingToRegister

public boolean isPendingToRegister()

Returns:

the pendingToRegister

setPendingToRegister

public void setPendingToRegister(boolean ispendingToRegister)

Parameters:

ispendingToRegister - the pendingToRegister to set

addLazyTask

protected void addLazyTask(ObjectID objectID,
                           ImplementationID implID,
                           MetaClassID classID)

Add lazy task to be run in DataClay.

Parameters:

objectID - ID of the object running the task

implID - ID of the implementation to run

classID - ID of the class in which the task is located
