abstract void com.quadcap.sql.Constraint.add (  Session  session  )  throws SQLException, IOException [pure virtual]
 

Called when the constraint is added.

Constraints which maintain state (e.g., indexes) can build their initial data structures (or whatever it is that they do at this time)

Implemented in com.quadcap.sql.AutoNumberConstraint, com.quadcap.sql.CheckConstraint, com.quadcap.sql.ForeignKeyConstraint, com.quadcap.sql.ImportedKeyConstraint, com.quadcap.sql.IndexConstraint, and com.quadcap.sql.NotNullConstraint.

abstract void com.quadcap.sql.Constraint.applyDelete (  Session  session,
Row  row,
long  rowId,
Constraint  activeIndex
)  throws SQLException, IOException [pure virtual]
 

Called after a row has been deleted, with the old row and row ID.

Constraints which maintain state (such as an index) would extend this class and implement this method to update the index.

Implemented in com.quadcap.sql.AutoNumberConstraint, com.quadcap.sql.CheckConstraint, com.quadcap.sql.ForeignKeyConstraint, com.quadcap.sql.ImportedKeyConstraint, com.quadcap.sql.IndexConstraint, and com.quadcap.sql.NotNullConstraint.

Called after the specified row has been inserted, with the resulting row ID, and with the active index.

Constraints which maintain state (such as an index) would extend this class and implement this method to update the index

Implemented in com.quadcap.sql.AutoNumberConstraint, com.quadcap.sql.CheckConstraint, com.quadcap.sql.ForeignKeyConstraint, com.quadcap.sql.ImportedKeyConstraint, com.quadcap.sql.IndexConstraint, and com.quadcap.sql.NotNullConstraint.

----UPDATE Called before a row is UPDATED, with an opportunity to signal a constraint violation if one can be detected.

Because the oldRow may be 'lazy', it's important to instantiate whatever items are going to be needed later by applyUpdate *now*, otherwise, apply may get the 'new' versions of those items, because the underlying byte stream is modified by the time applyUpdate gets called.
