getROWID

protected java.lang.Object getROWID(EntityImpl entityContext)

Get the ROWID attribute. The ROWID attribute can be used to gain faster access to the underyling database data. Obtain the value for the ROWID attribute. If this entity doesn't support ROWID attributes, then return NULL. If, for some reason the value of the ROWID attribute isn't present, then return null.

Overrides:

getROWID in class BaseSQLBuilderImpl

Returns:

the value of the ROWID attribute or null if not present or applicable to this entity.

buildWhereClause

public void buildWhereClause(EntityImpl entityContext,
                             java.lang.StringBuffer buffer,
                             AttributeDefImpl[] keyCols,
                             java.lang.Object rowid)

Construct a SQL WHERE clause for the Entity into the designated Buffer, based upon the Source Columns. This routine will construct a SQL WHERE clause in the StringBuffer passed. It does this by appending the various components of the WHERE Clause (based upon Primary Key columns) into the buffer area.

For now it's private. We'll only consider it public when we sort out all of the issues with Sources/Sinks.

The presence or absence of the ROWID value determines whether the ROWID will be used for Row access.

Specified by:

buildWhereClause in interface SQLBuilder

Overrides:

buildWhereClause in class BaseSQLBuilderImpl

Parameters:

buffer - the area into which the WHERE Clause will be placed.

keyCols - the Primary key columns.

rowid - the ROWID for the ROW if known.
