SYSCOLPERMSRowFactory

SYSCOLPERMSRowFactory(UUIDFactory uuidf,
                      ExecutionFactory ef,
                      DataValueFactory dvf)

Method Detail

makeRow

public ExecRow makeRow(TupleDescriptor td,
                       TupleDescriptor parent)
                throws StandardException

Description copied from class: CatalogRowFactory

most subclasses should provide this method. One or two oddball cases in Replication and SysSTATEMENTSRowFactory don't. For those we call makeRow with the additional arguments.

Overrides:

makeRow in class CatalogRowFactory

Throws:

StandardException

buildDescriptor

public TupleDescriptor buildDescriptor(ExecRow row,
                                       TupleDescriptor parentTuple,
                                       DataDictionary dataDictionary)
                                throws StandardException

builds a tuple descriptor from a row

Specified by:

buildDescriptor in class CatalogRowFactory

Throws:

StandardException

buildColumnList

public SystemColumn[] buildColumnList()
                               throws StandardException

builds a column list for the catalog

Specified by:

buildColumnList in class CatalogRowFactory

Throws:

StandardException

buildIndexKeyRow

public ExecIndexRow buildIndexKeyRow(int indexNumber,
                                     PermissionsDescriptor perm)
                              throws StandardException

builds an index key row for a given index number.

Specified by:

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,
                         boolean[] colsChanged)
                  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,
                             boolean[] colsChanged)
                      throws StandardException

Remove a set of permissions from a row from this catalog table

Specified by:

removePermissions 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:

-1 if there are no permissions left in the row, otherwise the number of columns that were changed.

Throws:

StandardException - standard error policy

setUUIDOfThePassedDescriptor

public void setUUIDOfThePassedDescriptor(ExecRow row,
                                         PermissionsDescriptor perm)
                                  throws StandardException

Description copied from class: PermissionsCatalogRowFactory

Set the uuid of the passed permission descriptor to the uuid of the row from the system table. DataDictionary will make this call before calling the dependency manager to send invalidation messages to the objects dependent on the permission descriptor's uuid.

Specified by:

setUUIDOfThePassedDescriptor in class PermissionsCatalogRowFactory

Parameters:

row - The row from the system table for the passed permission descriptor

perm - Permission descriptor

Throws:

StandardException
