Method Details
-
getReturnOpenType
Returns the open type of the values returned by the operation described by thisOpenMBeanOperationInfo
instance.- Specified by:
getReturnOpenType
in interfaceOpenMBeanOperationInfo
- Returns:
- the return type.
-
equals
Compares the specified
obj
parameter with thisOpenMBeanOperationInfoSupport
instance for equality.Returns
true
if and only if all of the following statements are true:obj
is non null,obj
also implements theOpenMBeanOperationInfo
interface,- their names are equal
- their signatures are equal
- their return open types are equal
- their impacts are equal
equals
method works properly forobj
parameters which are different implementations of theOpenMBeanOperationInfo
interface.- Specified by:
equals
in interfaceOpenMBeanOperationInfo
- Overrides:
equals
in classMBeanOperationInfo
- Parameters:
obj
- the object to be compared for equality with thisOpenMBeanOperationInfoSupport
instance;- Returns:
true
if the specified object is equal to thisOpenMBeanOperationInfoSupport
instance.- See Also:
Object.hashCode()
,HashMap
-
hashCode
public int hashCode()Returns the hash code value for this
OpenMBeanOperationInfoSupport
instance.The hash code of an
OpenMBeanOperationInfoSupport
instance is the sum of the hash codes of all elements of information used inequals
comparisons (ie: its name, return open type, impact and signature, where the signature hashCode is calculated by a call tojava.util.Arrays.asList(this.getSignature).hashCode()
).This ensures that
t1.equals(t2)
implies thatt1.hashCode()==t2.hashCode()
for any twoOpenMBeanOperationInfoSupport
instancest1
andt2
, as required by the general contract of the methodObject.hashCode()
.However, note that another instance of a class implementing the
OpenMBeanOperationInfo
interface may be equal to thisOpenMBeanOperationInfoSupport
instance as defined byequals(java.lang.Object)
, but may have a different hash code if it is calculated differently.As
OpenMBeanOperationInfoSupport
instances are immutable, the hash code for this instance is calculated once, on the first call tohashCode
, and then the same value is returned for subsequent calls.- Specified by:
hashCode
in interfaceOpenMBeanOperationInfo
- Overrides:
hashCode
in classObject
- Returns:
- the hash code value for this
OpenMBeanOperationInfoSupport
instance - See Also:
Object.equals(java.lang.Object)
,System.identityHashCode(java.lang.Object)
-
toString
Returns a string representation of this
OpenMBeanOperationInfoSupport
instance.The string representation consists of the name of this class (ie
javax.management.openmbean.OpenMBeanOperationInfoSupport
), and the name, signature, return open type and impact of the described operation and the string representation of its descriptor.As
OpenMBeanOperationInfoSupport
instances are immutable, the string representation for this instance is calculated once, on the first call totoString
, and then the same value is returned for subsequent calls.- Specified by:
toString
in interfaceOpenMBeanOperationInfo
- Overrides:
toString
in classObject
- Returns:
- a string representation of this
OpenMBeanOperationInfoSupport
instance
