Specified by:

getCatalogNumber in class PermissionsDescriptor

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object other)

Overrides:

equals in class Object

Returns:

checkOwner

public boolean checkOwner(String authorizationId)
                   throws StandardException

Description copied from class: PermissionsDescriptor

This method checks if the passed authorization id is same as the owner of the object on which this permission is defined. This method gets called by create view/constraint/trigger to see if this permission needs to be saved in dependency system for the view/constraint/trigger. If the same user is the owner of the the object being accessed and the newly created object, then no need to keep this privilege dependency

Specified by:

checkOwner in class PermissionsDescriptor

Returns:

boolean If passed authorization id is owner of the table

Throws:

StandardException

See Also:

• PermissionsDescriptor.checkOwner(String)

getProtectedObject

public static PrivilegedSQLObject getProtectedObject(DataDictionary dd,
 UUID objectID,
 String objectType)
                                              throws StandardException

Get the protected object.

Parameters:

dd - Metadata

objectID - Unique handle on the protected object

objectType - Type of the object

Throws:

StandardException

getObjectName

public String getObjectName()

Return the name of this Provider. (Useful for errors.)

Specified by:

getObjectName in interface Dependable

Returns:

String The name of this provider.

getClassType

public String getClassType()

Get the provider's type.

Specified by:

getClassType in interface Dependable

Returns:

char The provider's type.

getDependableFinder

public DependableFinder getDependableFinder()

Description copied from interface: Dependable

Get an object which can be written to disk and which, when read from disk, will find or reconstruct this in-memory Dependable.

Specified by:

getDependableFinder in interface Dependable

Returns:

the stored form of this provider
