Class MBeanAttributeInfo

public MBeanAttributeInfo(String name,
                          String type,
                          String desc,
                          boolean isReadable,
                          boolean isWritable,
                          boolean isIs)

Constructs a new MBeanAttributeInfo using the specified name, description and type with the given settings for the accessor and mutator methods.

Parameters:

name - the name of the attribute.

type - the type of the attribute, in the form of its class name.

desc - a description of the attribute.

isReadable - true if the attribute's value can be read.

isWritable - true if the attribute's value can be changed.

isIs - true if the attribute uses an accessor of the form isXXX.

Throws:

IllegalArgumentException - if the attribute is both unreadable and unwritable.

public MBeanAttributeInfo(String name,
                          String desc,
                          Method getter,
                          Method setter)
            throws IntrospectionException

Constructs a new MBeanAttributeInfo using the specified name and description, with the given accessor and mutator methods. A null value for the accessor method indicates that the value can not be read. A null value for the mutator method indicates that the value can not be changed.

Parameters:

name - the name of the attribute.

desc - a description of the attribute.

getter - the accessor method, or null if the value can not be read.

setter - the mutator method, or null if the value can not be changed.

Throws:

IntrospectionException - if both the accessor and mutator method are null.

public Object clone()

Returns a clone of this instance. The clone is created using just the method provided by Object. Thus, the clone is just a shallow clone as returned by that method, and does not contain any deeper cloning based on the subject of this class.

Overrides:

clone in interface Object

Returns:

a clone of this instance.

Cloneable

public boolean equals(Object obj)

Compares this feature with the supplied object. This returns true iff the object is an instance of MBeanAttributeInfo, Object.equals() returns true for a comparison of both the name and description of this attribute with that of the specified object (performed by the superclass), and the type and boolean flags of the two instances are equal.

Overrides:

equals in interface MBeanFeatureInfo

Parameters:

obj - the object to compare.

Returns:

true if the object is a MBeanAttributeInfo instance, name.equals(object.getName()), description.equals(object.getDescription()), attributeType.equals(object.getType()), isRead == object.isReadable(), isWrite == object.isWritable(), is == object.isIs()

public String getType()

Returns the type of this attribute, in the form of its class name.

Returns:

the type of this attribute.

public int hashCode()

Returns the hashcode of the attribute information as the sum of the hashcode of the superclass, the hashcode of the type, the hashcode of isReadable(), twice the hashcode of isWritable() and four times the hashcode of isIs().

Overrides:

hashCode in interface MBeanFeatureInfo

Returns:

the hashcode of the attribute information.

public boolean isIs()

Returns true if the accessor method of this attribute is of the form isXXX.

Returns:

true if the accessor takes the form isXXX.

public boolean isReadable()

Returns true if value of this attribute can be read.

Returns:

true if the value of the attribute can be read.

public boolean isWritable()

Returns true if the value of this attribute can be changed.

Returns:

true if the value of the attribute can be changed.

public String toString()

Returns a textual representation of this instance. This is constructed using the class name (javax.management.MBeanAttributeInfo), the name, description and type of the attribute and the current settings of the isReadable(), isWritable() and isIs() properties.

As instances of this class are immutable, the return value is computed just once for each instance and reused throughout its life.

Overrides:

toString in interface MBeanFeatureInfo

Returns:

a @link{java.lang.String} instance representing the instance in textual form.
