Interface OpenMBeanAttributeInfo
-
- All Superinterfaces:
- OpenMBeanParameterInfo
- All Known Implementing Classes:
- OpenMBeanAttributeInfoSupport
public interface OpenMBeanAttributeInfo extends OpenMBeanParameterInfo
Describes an attribute of an open MBean.
This interface declares the same methods as the class
MBeanAttributeInfo. A class implementing this interface (typicallyOpenMBeanAttributeInfoSupport) should extendMBeanAttributeInfo.- Since:

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 thisOpenMBeanAttributeInfoinstance for equality.Returns true if and only if all of the following statements are true:
- obj is non null,
- obj also implements the
OpenMBeanAttributeInfointerface, - 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.

equalsin classObject - Parameters:
-
obj- the object to be compared for equality with thisOpenMBeanAttributeInfoinstance; - Returns:
-
trueif the specified object is equal to thisOpenMBeanAttributeInfoinstance. - See Also:

Object.hashCode(),HashMap
hashCode
int hashCode()
Returns the hash code value for thisOpenMBeanAttributeInfoinstance.The hash code of an
OpenMBeanAttributeInfoinstance is the sum of the hash codes of all elements of information used inequalscomparisons (ie: its name, its open type, and its default, min, max and legal values).This ensures that
t1.equals(t2)implies thatt1.hashCode()==t2.hashCode()for any twoOpenMBeanAttributeInfoinstancest1andt2, as required by the general contract of the methodObject.hashCode().- Specified by:
-
hashCodein interfaceOpenMBeanParameterInfo - Overrides:
-
hashCodein classObject - Returns:
-
the hash code value for this
OpenMBeanAttributeInfoinstance - See Also:
-
Object.equals(java.lang.Object),System.identityHashCode(java.lang.Object)
toString
String toString()
Returns a string representation of thisOpenMBeanAttributeInfoinstance.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:
-
toStringin interfaceOpenMBeanParameterInfo - Overrides:
-
toStringin classObject - Returns:
-
a string representation of this
OpenMBeanAttributeInfoinstance
