# PredicateReaderMBean (Abstract)

Overview | Related MBeans | Attributes | Operations

## Overview

This MBean reads data about predicates and their arguments. This is a type-safe interface for a WebLogic Server MBean, which you can import into your client classes and access through `weblogic.management.MBeanHome`. As of 9.0, the `MBeanHome` interface and all type-safe interfaces for WebLogic Server MBeans are deprecated. Instead, client classes that interact with WebLogic Server MBeans should use standard JMX design patterns in which clients use the `javax.management.MBeanServerConnection` interface to discover MBeans, attributes, and attribute types at runtime. For more information, see "Developing Manageable Applications with JMX" on http://edocs.bea.com.

Fully Qualified Interface Name | If you use the `getMBeanInfo` operation in MBeanTypeServiceMBean, supply the following value as this MBean's fully qualified interface name: `weblogic.management.security.authorization.PredicateReaderMBean`
Factory Methods | No factory methods. Instances of this MBean are created automatically.
Subtypes | The following MBeans extend or implement this MBean type:
PredicateEditorMBean DefaultAuthorizerMBean DefaultRoleMapperMBean | XACMLAuthorizerMBean XACMLRoleMapperMBean
