Class ModelMBeanConstructorInfo

java.lang.Object
  extended by javax.management.MBeanFeatureInfo
      extended by javax.management.MBeanConstructorInfo
          extended by 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: 

 name           : constructor name 
 descriptorType : must be "operation"  
 role           : must be "constructor"
 displayName    : human readable name of constructor 
 visibility            : 1-4 where 1: always visible 4: rarely visible 
 presentationString :  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.

Since:
1.5

Constructor Detail

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 fields 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 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 not equal to "constructor".
Method Detail

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 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 not equal to "constructor".
See Also:
getDescriptor()

toString

public String toString()
Returns a string containing the entire contents of the ModelMBeanConstructorInfo in human readable form.

Overrides:
toString in class MBeanConstructorInfo
Returns:
a string representation of the object.
