All Superinterfaces:

OpenMBeanParameterInfo

All Known Implementing Classes:

OpenMBeanAttributeInfoSupport

public interface OpenMBeanAttributeInfo
extends OpenMBeanParameterInfo

Describes an attribute associated with an open management bean. This interface includes those methods specified by MBeanAttributeInfo, so implementations should extend this class.

1.5

Method Summary

Methods

Modifier and Type	Method and Description
boolean	equals(Object obj) Compares this attribute with the supplied object.
int	hashCode() Returns the hashcode of the attribute information as the sum of the hashcodes of the name, open type, default value, maximum value, minimum value, the set of legal values and the access properties.
boolean	isIs() Returns true if the accessor method of this attribute is of the form isXXX.
boolean	isReadable() Returns true if value of this attribute can be read.

Method Detail

equals

boolean equals(Object obj)

Compares this attribute with the supplied object. This returns true iff the object is an instance of OpenMBeanAttributeInfo with an equal name and open type, the same default, minimum, maximum and legal values and the same access properties (isIs(), isReadable(), isWritable()).

Specified by:

equals in interface OpenMBeanParameterInfo

Overrides:

equals in class Object

Parameters:

obj - the object to compare.

Returns:

true if the object is a OpenMBeanParameterInfo instance, name.equals(object.getName()), openType.equals(object.getOpenType()), defaultValue.equals(object.getDefaultValue()), minValue.equals(object.getMinValue()), maxValue.equals(object.getMaxValue()), legalValues.equals(object.getLegalValues()), is == object.isIs(), isRead == object.isReadable(), and isWrite == object.isWritable().

Object.hashCode()

hashCode

int hashCode()

Returns the hashcode of the attribute information as the sum of the hashcodes of the name, open type, default value, maximum value, minimum value, the set of legal values and the access properties.

Specified by:

hashCode in interface OpenMBeanParameterInfo

Overrides:

hashCode in class Object

Returns:

the hashcode of the attribute information.

Object.equals(Object), System.identityHashCode(Object)

isIs

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.

isReadable

boolean isReadable()

Returns true if value of this attribute can be read.

Returns:

true if the value of the attribute can be read.

isWritable

boolean isWritable()

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

Returns:

true if the value of the attribute can be changed.

toString

String toString()

Returns a textual representation of this instance. This is constructed using the class name (javax.management.openmbean.OpenMBeanAttributeInfo) along with the name, open type, default, minimum, maximum and legal values of the parameter and the access permissions (isIs(), isReadable(), isWritable()).

Specified by:

toString in interface OpenMBeanParameterInfo

Overrides:

toString in class Object

Returns:

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