Overview

Provides operations for discovering the attributes and operations of an MBean type that has not yet been instantiated.

The javax.management.ObjectName of this MBean is "com.bea:Name=MBeanTypeService,Type=weblogic.management.mbeanservers.MBeanTypeService".

Since	9.0.0.0
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.mbeanservers.MBeanTypeService`
Factory Methods	No factory methods. Instances of this MBean are created automatically.

Operations

This section describes the following operations:

getMBeanInfo
getSubtypes
validateAttribute
validateAttribute

validateAttributes
validateAttributes

getMBeanInfo

Returns the MBean info object for the specified interface.

For example,
MBeanServerConnection.invoke(MBeanTypeServiceMBean, "getMBeanInfo",
new Object[] { "weblogic.security.providers.authorization.DefaultAuthorizationProviderMBean" }
new String[] { "java.lang.String" });

Operation Name	`"getMBeanInfo"`
Parameters	`Object [] { beanInterface }` where: `beanInterface` is an object of type `java.lang.String` that specifies: The fully-qualified interface name of the MBean.
Signature	`String [] { "java.lang.String" }`
Returns	`ModelMBeanInfo`
Exceptions	`javax.management.OperationsException`

getSubtypes

Returns the names of all MBean types that extend or implement the specified MBean.

Operation Name	`"getSubtypes"`
Parameters	`Object [] { beanInterface }` where: `beanInterface` is an object of type `java.lang.String` that specifies: The fully-qualified interface name of the base MBean.
Signature	`String [] { "java.lang.String" }`
Returns	`class`

validateAttribute

Validates that the specified attribute value complies with the contraints for that attribute.

This operation evaluates the following types of constraints:

If the value you specify falls within an allowed minimum or maximum range.
If the value you specify is one of a set of enumerated allowed values.
If you pass a null value, this operation evaluates whether the attribute is allowed to contain a null value.

There are two signatures for this operation. One takes the interface name of an MBean type and the other takes the javax.management.ObjectName of an MBean instance.

Operation Name	`"validateAttribute"`
Parameters	`Object [] { beanInterface, attribute }` where: `beanInterface` is an object of type `java.lang.String` that specifies: The fully-qualified interface name of the MBean that contains the attribute. `attribute` is an object of type `javax.management.Attribute` that specifies: The name of the attribute and a proposed value.
Signature	`String [] { "java.lang.String", "javax.management.Attribute" }`
Returns	`void`
Exceptions	`javax.management.AttributeNotFoundException` AttributeNotFoundException if the attribute is not specified for the interface. `javax.management.InvalidAttributeValueException` InvalidAttributeValueException if the value violates any of the constraints `javax.management.MBeanException` MBeanException if the interface is not recognized. `javax.management.ReflectionException` ReflectionException if the attribute type or the bean interface cannot be loaded.

validateAttribute

Validates that the specified attribute value complies with the contraints for that attribute.

This operation evaluates the following types of constraints:

If the value you specify falls within an allowed minimum or maximum range.
If the value you specify is one of a set of enumerated allowed values.
If you pass a null value, this operation evaluates whether the attribute is allowed to contain a null value.

There are two signatures for this operation. One takes the interface name of an MBean type and the other takes the javax.management.ObjectName of an MBean instance.

Operation Name	`"validateAttribute"`
Parameters	`Object [] { beanInstance, attribute }` where: `beanInstance` is an object of type `javax.management.ObjectName` that specifies: An MBean instance. `attribute` is an object of type `javax.management.Attribute` that specifies: The name of the attribute and a proposed value.
Signature	`String [] { "javax.management.ObjectName", "javax.management.Attribute" }`
Returns	`void`
Exceptions	`javax.management.AttributeNotFoundException` AttributeNotFoundException if the attribute is not specified for the interface. `javax.management.InvalidAttributeValueException` InvalidAttributeValueException if the value violates any of the constraints `javax.management.MBeanException` MBeanException if the interface is not recognized. `javax.management.ReflectionException` ReflectionException if the attribute type or the bean interface cannot be loaded.

validateAttributes

Validates a set of attributes with a single invocation.

If all of the attribute values are valid, this operation returns an empty AttributeList. For each invalid attribute value, operation stores an exception the AttributeList that is returned.

There are two signatures for this operation. One takes the interface name of an MBean type and the other takes the javax.management.ObjectName of an MBean instance.

validateAttribute

Operation Name	`"validateAttributes"`
Parameters	`Object [] { beanInterface, attributes }` where: `beanInterface` is an object of type `java.lang.String` that specifies: The fully-qualified interface name of the MBean that contains the attributes. `attributes` is an object of type `javax.management.AttributeList` that specifies: The names of the attributes and proposed values.
Signature	`String [] { "java.lang.String", "javax.management.AttributeList" }`
Returns	`AttributeList`
Exceptions	`javax.management.MBeanException` MBeanException if the interface is not recognized. `javax.management.ReflectionException` ReflectionException if the attribute type or the bean interface cannot be loaded.

validateAttributes

Validates a set of attributes with a single invocation.

If all of the attribute values are valid, this operation returns an empty AttributeList. For each invalid attribute value, operation stores an exception the AttributeList that is returned.

There are two signatures for this operation. One takes the interface name of an MBean type and the other takes the javax.management.ObjectName of an MBean instance.

For more information, see:

validateAttributes(String beanInterface, AttributeList)

Operation Name	`"validateAttributes"`
Parameters	`Object [] { beanInstance, attributes }` where: `beanInstance` is an object of type `javax.management.ObjectName` that specifies: An MBean instance. `attributes` is an object of type `javax.management.AttributeList` that specifies: the names of the attributes and a proposed values.
Signature	`String [] { "javax.management.ObjectName", "javax.management.AttributeList" }`
Returns	`AttributeList`
Exceptions	`javax.management.MBeanException` MBeanException if the interface is not recognized. `javax.management.ReflectionException` ReflectionException if the attribute type or the bean interface cannot be loaded.
