Constructor Detail

TablePrivilegeInfo

public TablePrivilegeInfo(TableDescriptor td,
                          boolean[] actionAllowed,
                          FormatableBitSet[] columnBitSets,
                          java.util.List descriptorList)

Parameters:

actionAllowed - actionAllowed[action] is true if action is in the privilege set.

Method Detail

checkOwnership

protected void checkOwnership(java.lang.String user,
                              TableDescriptor td,
                              SchemaDescriptor sd,
                              DataDictionary dd,
                              LanguageConnectionContext lcc,
                              boolean grant)
                       throws StandardException

Determines whether a user is the owner of an object (table, function, or procedure). Note that the database creator can access database objects without needing to be their owner.

Parameters:

user - authorizationId of current user

td - table descriptor being checked against

sd - SchemaDescriptor

dd - DataDictionary

lcc - LanguageConnectionContext

grant - grant if true; revoke if false

Throws:

StandardException - if user does not own the object

checkPrivileges

private void checkPrivileges(java.lang.String user,
                             TableDescriptor td,
                             SchemaDescriptor sd,
                             DataDictionary dd,
                             LanguageConnectionContext lcc)
                      throws StandardException

Determines if the privilege is grantable by this grantor for the given view. Note that the database owner can access database objects without needing to be their owner. This method should only be called if it is a GRANT.

Parameters:

user - authorizationId of current user

td - TableDescriptor to be checked against

sd - SchemaDescriptor

dd - DataDictionary

lcc - LanguageConnectionContext

Throws:

StandardException - if user does not have permission to grant

executeGrantRevoke

public void executeGrantRevoke(Activation activation,
                               boolean grant,

                        throws StandardException

This is the guts of the Execution-time logic for GRANT/REVOKE of a table privilege

Specified by:

Parameters:

activation -

grant - true if grant, false if revoke

grantees - a list of authorization ids (strings)

Throws:

StandardException - Thrown on failure

                                         boolean forGrantOption)

hasColumnPermissions

private boolean hasColumnPermissions(int action)
