Interface OpenMBeanAttributeInfo
All Superinterfaces: OpenMBeanParameterInfo
All Known Implementing Classes: OpenMBeanAttributeInfoSupport
public interface OpenMBeanAttributeInfoextends OpenMBeanParameterInfo
Describes an attribute of an open MBean.
This interface declares the same methods as the class MBeanAttributeInfo. A class implementing this
interface (typically OpenMBeanAttributeInfoSupport) should
extend MBeanAttributeInfo.
Since:
1.5
Method Summary
boolean
equals(Object obj)
Compares the specified obj parameter with this OpenMBeanAttributeInfo instance for equality.
int
hashCode()
Returns the hash code value for this OpenMBeanAttributeInfo instance.
boolean
isIs()
Returns true if the attribute described by this OpenMBeanAttributeInfo instance
is accessed through a isXXX getter (applies only to boolean and Boolean values),
false otherwise.
boolean
isReadable()
Returns true if the attribute described by this OpenMBeanAttributeInfo instance is readable,
false otherwise.
boolean
isWritable()
Returns true if the attribute described by this OpenMBeanAttributeInfo instance is writable,
false otherwise.
String
toString()
Returns a string representation of this OpenMBeanAttributeInfo instance.

Method Detail
isReadable
boolean isReadable()
Returns true if the attribute described by this OpenMBeanAttributeInfo instance is readable,
false otherwise.
Returns:true if the attribute is readable.
isWritable
boolean isWritable()
Returns true if the attribute described by this OpenMBeanAttributeInfo instance is writable,
false otherwise.
Returns:true if the attribute is writable.
isIs
boolean isIs()
Returns true if the attribute described by this OpenMBeanAttributeInfo instance
is accessed through a isXXX getter (applies only to boolean and Boolean values),
false otherwise.
Returns:true if the attribute is accessed through isXXX.
equals
boolean equals(Object obj)
Compares the specified obj parameter with this OpenMBeanAttributeInfo instance for equality.
Returns true if and only if all of the following statements are true:
obj is non null,
obj also implements the OpenMBeanAttributeInfo interface,
their names are equal
their open types are equal
their access properties (isReadable, isWritable and isIs) are equal
their default, min, max and legal values are equal.
This ensures that this equals method works properly for obj parameters which are
different implementations of the OpenMBeanAttributeInfo interface.
Specified by:equals in interface OpenMBeanParameterInfoOverrides:equals in class Object
Parameters:obj - the object to be compared for equality with this OpenMBeanAttributeInfo instance;
Returns:true if the specified object is equal to this OpenMBeanAttributeInfo instance.See Also:Object.hashCode(),
Hashtable
hashCode
int hashCode()
Returns the hash code value for this OpenMBeanAttributeInfo instance.
The hash code of an OpenMBeanAttributeInfo instance is the sum of the hash codes
of all elements of information used in equals comparisons
(ie: its name, its open type, and its default, min, max and legal values).
This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode()
for any two OpenMBeanAttributeInfo instances t1 and t2,
as required by the general contract of the method
Object.hashCode().
Specified by:hashCode in interface OpenMBeanParameterInfoOverrides:hashCode in class Object
Returns:the hash code value for this OpenMBeanAttributeInfo instanceSee Also:Object.equals(java.lang.Object),
Hashtable
toString
String toString()
Returns a string representation of this OpenMBeanAttributeInfo instance.
The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanAttributeInfo),
the string representation of the name and open type of the described attribute,
and the string representation of its default, min, max and legal values.
Specified by:toString in interface OpenMBeanParameterInfoOverrides:toString in class Object
Returns:a string representation of this OpenMBeanAttributeInfo instance
