public Class PermDescriptor

Constructor

Parameters

dataDictionary:DataDictionary

data dictionary

permUUID:UUID

unique identification in time and space of this perm descriptor

objectType:String

E.g., SEQUENCE_TYPE

permObjectId:UUID

Unique id of the object being protected

permission:String

E.g., USAGE_PRIV

grantor:String

Authorization id which confers the privilege

grantee:String

Authorization id which receives the privilege

isGrantable:boolean

True if the privilege can be granted onwards

Implements abstract org.apache.derby.iapi.sql.dictionary.PermissionsDescriptor.checkOwner.

Doc from org.apache.derby.iapi.sql.dictionary.PermissionsDescriptor.checkOwner.

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

Returns:boolean

boolean If passed authorization id is owner of the table

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

other:Object

the reference object with which to compare.

Returns:boolean

true iff the key part of this perm descriptor equals the key part of another perm descriptor.

Implements abstract org.apache.derby.iapi.sql.dictionary.PermissionsDescriptor.getCatalogNumber.

Implements org.apache.derby.catalog.Dependable.getClassType.

Get the provider's type.

Returns:String

char The provider's type.

Implements org.apache.derby.catalog.Dependable.getDependableFinder.

Doc from org.apache.derby.catalog.Dependable.getDependableFinder.

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

Returns:DependableFinder

the stored form of this provider

Dependable#getDependableFinder

Implements org.apache.derby.catalog.Dependable.getObjectName.

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

Returns:String

String The name of this provider.

Get the protected object.

Parameters

dd:DataDictionary

Metadata

objectID:UUID

Unique handle on the protected object

objectType:String

Type of the object

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns:int

the hashCode for the key part of this permissions descriptor

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Returns:String

a string representation of the object
