Class ExecutableTextHolderJoin

java.lang.Object
  oracle.odi.interfaces.interactive.support.textholder.ExecutableTextHolderGenericClause
      oracle.odi.interfaces.interactive.support.textholder.ExecutableTextHolderJoin

All Implemented Interfaces:

IExecutableTextHolder

public class ExecutableTextHolderJoin
extends ExecutableTextHolderGenericClause

The text holder for joins.
This particular text holder is always in a DataSet and has 2 attached SourceDataStores.
Note that on Lookup Joins, the second attached source datastore cannot be set, as it is tightly bound to the SourceDataStore of the Lookup.

Method Summary

SourceDataStore[]	getAttachedSourceDataStores() Gets the attached source datastores of this TextHolder.
int	getNumberOfDataStores() Gets the number of source datastores.
boolean	isAttachedSourceDataStoreSettable(int pDataStoreNumber) Returns whether it is possible to set this particular datastore number.
void	setAttachedSourceDataStore(int pDataStoreNumber, SourceDataStore pSourceDataStore) Sets one attached SourceDataStore.

Method Detail

getAttachedSourceDataStores

public SourceDataStore[] getAttachedSourceDataStores()

Gets the attached source datastores of this TextHolder.

Returns:

the attached datastores

getNumberOfDataStores

public int getNumberOfDataStores()

Description copied from interface: IExecutableTextHolder

Gets the number of source datastores. This should be equal to getAttachedSourceDataStores().length.

Returns:

the number of attached datastores

isAttachedSourceDataStoreSettable

public boolean isAttachedSourceDataStoreSettable(int pDataStoreNumber)

Description copied from interface: IExecutableTextHolder

Returns whether it is possible to set this particular datastore number.

Parameters:

pDataStoreNumber - the position of the datastore

Returns:

true if it is possible to call setAttachedSourceDataStore(pDataStoreNumber, aSourceDataStore)

public void setAttachedSourceDataStore(int pDataStoreNumber,
                                       SourceDataStore pSourceDataStore)

Description copied from interface: IExecutableTextHolder

Sets one attached SourceDataStore. Please make sure that the pDataStoreNumber is settable by using isAttachedSourceDataStoreSettable().

Parameters:

pDataStoreNumber - the number of the attached SourceDataStore to be set

pSourceDataStore - the source datastore to attach
