buildIndexKeyRow in class PermissionsCatalogRowFactory

perm - a permission descriptor of the appropriate class for this PermissionsCatalogRowFactory class.

Throws:

StandardException - standard error policy

getPrimaryKeyIndexNumber

public int getPrimaryKeyIndexNumber()

Description copied from class: CatalogRowFactory

Get the index number for the primary key index on this catalog.

Overrides:

getPrimaryKeyIndexNumber in class CatalogRowFactory

Returns:

a 0-based number

orPermissions

public int orPermissions(ExecRow row,
                         PermissionsDescriptor perm,

                  throws StandardException

Or a set of permissions in with a row from this catalog table

Specified by:

orPermissions in class PermissionsCatalogRowFactory

Parameters:

row - an existing row

perm - a permission descriptor of the appropriate class for this PermissionsCatalogRowFactory class.

colsChanged - An array with one element for each column in row. It is updated to indicate which columns in row were changed

Returns:

The number of columns that were changed.

Throws:

StandardException - standard error policy

removePermissions

public int removePermissions(ExecRow row,
                             PermissionsDescriptor perm,

Specified by:

removePermissions in class PermissionsCatalogRowFactory

Parameters:

row - an existing row

perm - a permission descriptor of the appropriate class for this PermissionsCatalogRowFactory class.
