Constructor Details

PrivilegeNode

PrivilegeNode(int objectType,
 Object objectOfPrivilege,
 TablePrivilegesNode specificPrivileges,
 ContextManager cm)
       throws StandardException

Initialize a PrivilegeNode for use against SYS.SYSTABLEPERMS and SYS.SYSROUTINEPERMS.

Parameters:

objectType -

objectOfPrivilege - (a TableName or RoutineDesignator)

specificPrivileges - null for routines and usage

cm - the context manager

Throws:

StandardException

PrivilegeNode

PrivilegeNode(int objectType,
 TableName objectName,
 String privilege,
 boolean restrict,
 ContextManager cm)

Constructor a PrivilegeNode for use against SYS.SYSPERMS.

Parameters:

objectType - E.g., SEQUENCE

objectName - A possibles schema-qualified name

privilege - A PermDescriptor privilege, e.g. PermDescriptor.USAGE_PRIV

restrict - True if this is a REVOKE...RESTRICT action

cm - The context manager

Method Details

bind

public QueryTreeNode bind(HashMap<Provider,Provider> dependencies,
 List<String> grantees,
 boolean isGrant)
                   throws StandardException

Bind this GrantNode. Resolve all table, column, and routine references. Register a dependency on the object of the privilege if it has not already been done

Parameters:

dependencies - The list of privilege objects that this statement has already seen. If the object of this privilege is not in the list then this statement is registered as dependent on the object.

grantees - The list of grantees

isGrant - grant if true; revoke if false

Returns:

the bound node

Throws:

StandardException - Standard error policy.

makePrivilegeInfo

PrivilegeInfo makePrivilegeInfo()
                         throws StandardException

Returns:

PrivilegeInfo for this node

Throws:

StandardException

unimplementedFeature

private StandardException unimplementedFeature()

Report an unimplemented feature

acceptChildren

void acceptChildren(Visitor v)
             throws StandardException

Description copied from class: QueryTreeNode

Accept a visitor on all child nodes. All sub-classes that add fields that should be visited, should override this method and call accept(v) on all visitable fields, as well as super.acceptChildren(v) to make sure all visitable fields defined by the super-class are accepted too.

Overrides:

acceptChildren in class QueryTreeNode

Parameters:

v - the visitor

Throws:

StandardException - on errors raised by the visitor
