javax.management.MBeanConstructorInfo

javax.management.modelmbean.ModelMBeanConstructorInfo

All Implemented Interfaces:

Serializable, Cloneable, DescriptorAccess, DescriptorRead

public class ModelMBeanConstructorInfo
extends MBeanConstructorInfo
implements DescriptorAccess

The ModelMBeanConstructorInfo object describes a constructor of the ModelMBean. It is a subclass of MBeanConstructorInfo with the addition of an associated Descriptor and an implementation of the DescriptorAccess interface.

The fields in the descriptor are defined, but not limited to, the following. Note that when the Type in this table is Number, a String that is the decimal representation of a Long can also be used.

ModelMBeanConstructorInfo Fields

Name	Type	Meaning
name	String	Constructor name.
descriptorType	String	Must be "operation".
role	String	Must be "constructor".
displayName	String	Human readable name of constructor.
visibility	Number	1-4 where 1: always visible 4: rarely visible.
presentationString	String	XML formatted string to describe how to present operation

The persistPolicy and currencyTimeLimit fields are meaningless for constructors, but are not considered invalid.

The default descriptor will have the name, descriptorType, displayName and role fields.

The serialVersionUID of this class is 3862947819818064362L.

Constructor Details

ModelMBeanConstructorInfo

public ModelMBeanConstructorInfo(String description, Constructor<?> constructorMethod)

Constructs a ModelMBeanConstructorInfo object with a default descriptor. The Descriptor of the constructed object will include fields contributed by any annotations on the Constructor object that contain the DescriptorKey meta-annotation.

Parameters:

description - A human readable description of the constructor.

constructorMethod - The java.lang.reflect.Constructor object describing the MBean constructor.

ModelMBeanConstructorInfo

public ModelMBeanConstructorInfo(String description, Constructor<?> constructorMethod, Descriptor descriptor)

Constructs a ModelMBeanConstructorInfo object. The Descriptor of the constructed object will include fields contributed by any annotations on the Constructor object that contain the DescriptorKey meta-annotation.

Parameters:

description - A human readable description of the constructor.

constructorMethod - The java.lang.reflect.Constructor object describing the ModelMBean constructor.

descriptor - An instance of Descriptor containing the appropriate metadata for this instance of the ModelMBeanConstructorInfo. If it is null, then a default descriptor will be created. If the descriptor does not contain the field "displayName" this field is added in the descriptor with its default value.

Throws:

RuntimeOperationsException - Wraps an IllegalArgumentException. The descriptor is invalid, or descriptor field "name" is not equal to name parameter, or descriptor field "descriptorType" is not equal to "operation" or descriptor field "role" is present but not equal to "constructor".

ModelMBeanConstructorInfo

public ModelMBeanConstructorInfo(String name, String description, MBeanParameterInfo[] signature)

Constructs a ModelMBeanConstructorInfo object with a default descriptor.

Parameters:

name - The name of the constructor.

description - A human readable description of the constructor.

signature - MBeanParameterInfo object array describing the parameters(arguments) of the constructor.

ModelMBeanConstructorInfo

public ModelMBeanConstructorInfo(String name, String description, MBeanParameterInfo[] signature, Descriptor descriptor)

Constructs a ModelMBeanConstructorInfo object.

Parameters:

name - The name of the constructor.

description - A human readable description of the constructor.

signature - MBeanParameterInfo objects describing the parameters(arguments) of the constructor.

descriptor - An instance of Descriptor containing the appropriate metadata for this instance of the MBeanConstructorInfo. If it is null then a default descriptor will be created. If the descriptor does not contain the field "displayName" this field is added in the descriptor with its default value.

Throws:

RuntimeOperationsException - Wraps an IllegalArgumentException. The descriptor is invalid, or descriptor field "name" is not equal to name parameter, or descriptor field "descriptorType" is not equal to "operation" or descriptor field "role" is present but not equal to "constructor".

Method Details

clone

public Object clone()

Creates and returns a new ModelMBeanConstructorInfo which is a duplicate of this ModelMBeanConstructorInfo.

Overrides:

clone in class MBeanConstructorInfo

Returns:

a clone of this instance.

See Also:

Cloneable

getDescriptor

public Descriptor getDescriptor()

Returns a copy of the associated Descriptor.

Specified by:

getDescriptor in interface DescriptorRead

Overrides:

getDescriptor in class MBeanFeatureInfo

Returns:

Descriptor associated with the ModelMBeanConstructorInfo object.

See Also:

setDescriptor(javax.management.Descriptor)

setDescriptor

public void setDescriptor(Descriptor inDescriptor)

Sets associated Descriptor (full replace) of ModelMBeanConstructorInfo. If the new Descriptor is null, then the associated Descriptor reverts to a default descriptor. The Descriptor is validated before it is assigned. If the new Descriptor is invalid, then a RuntimeOperationsException wrapping an IllegalArgumentException is thrown.

Specified by:

setDescriptor in interface DescriptorAccess

Parameters:

inDescriptor - replaces the Descriptor associated with the ModelMBeanConstructor. If the descriptor does not contain all the following fields, the missing ones are added with their default values: displayName, name, role, descriptorType.

Throws:

RuntimeOperationsException - Wraps an IllegalArgumentException. The descriptor is invalid, or descriptor field "name" is present but not equal to name parameter, or descriptor field "descriptorType" is present but not equal to "operation" or descriptor field "role" is present but not equal to "constructor".

getDescriptor()

toString

public String toString()

Returns a string containing the entire contents of the ModelMBeanConstructorInfo in human readable form.

Overrides:

toString in class Object

Returns:

a string representation of the object.
