Constructor Detail
OpenMBeanConstructorInfoSupport
public OpenMBeanConstructorInfoSupport(String name, String description, OpenMBeanParameterInfo[] signature)
Constructs an OpenMBeanConstructorInfoSupport
instance, which describes the constructor of a class of open MBeans with the specified name
, description
and signature
.
The signature
array parameter is internally copied, so that subsequent changes to the array referenced by
signature
have no effect on this instance.
- Parameters:
-
name
- cannot be a null or empty string. -
description
- cannot be a null or empty string. -
signature
- can be null or empty if there are no parameters to describe. - Throws:
-
IllegalArgumentException
- ifname
ordescription
are null or empty string. -
ArrayStoreException
- Ifsignature
is not an array of instances of a subclass ofMBeanParameterInfo
.
OpenMBeanConstructorInfoSupport
public OpenMBeanConstructorInfoSupport(String name, String description, OpenMBeanParameterInfo[] signature, Descriptor descriptor)
Constructs an OpenMBeanConstructorInfoSupport
instance, which describes the constructor of a class of open MBeans with the specified name
, description
, signature
, and descriptor
.
The signature
array parameter is internally copied, so that subsequent changes to the array referenced by
signature
have no effect on this instance.
- Parameters:
-
name
- cannot be a null or empty string. -
description
- cannot be a null or empty string. -
signature
- can be null or empty if there are no parameters to describe. -
descriptor
- The descriptor for the constructor. This may be null which is equivalent to an empty descriptor. - Throws:
-
IllegalArgumentException
- ifname
ordescription
are null or empty string. -
ArrayStoreException
- Ifsignature
is not an array of instances of a subclass ofMBeanParameterInfo
. - Since:

Method Detail
equals
public boolean equals(Object obj)
Compares the specified obj
parameter with this OpenMBeanConstructorInfoSupport
instance for equality.
Returns true
if and only if all of the following statements are true:
-
obj
is non null, -
obj
also implements theOpenMBeanConstructorInfo
interface, - their names are equal
- their signatures are equal.
equals
method works properly for obj
parameters which are different implementations of the OpenMBeanConstructorInfo
interface.- Specified by:
-
equals
in interfaceOpenMBeanConstructorInfo
- Overrides:
-
equals
in classMBeanConstructorInfo
- Parameters:
-
obj
- the object to be compared for equality with thisOpenMBeanConstructorInfoSupport
instance; - Returns:
-
true
if the specified object is equal to thisOpenMBeanConstructorInfoSupport
instance. - See Also:
-
Object.hashCode()
,HashMap
hashCode
public int hashCode()
Returns the hash code value for this
OpenMBeanConstructorInfoSupport
instance.
The hash code of an OpenMBeanConstructorInfoSupport
instance is the sum of the hash codes of all elements of information used in equals
comparisons (ie: its name and signature, where the signature hashCode is calculated by a call to
java.util.Arrays.asList(this.getSignature).hashCode()
).
This ensures that t1.equals(t2)
implies that
t1.hashCode()==t2.hashCode()
for any two
OpenMBeanConstructorInfoSupport
instances t1
and t2
, as required by the general contract of the method Object.hashCode()
.
However, note that another instance of a class implementing the OpenMBeanConstructorInfo
interface may be equal to this OpenMBeanConstructorInfoSupport
instance as defined by equals(java.lang.Object)
, but may have a different hash code if it is calculated differently.
As OpenMBeanConstructorInfoSupport
instances are immutable, the hash code for this instance is calculated once, on the first call to hashCode
, and then the same value is returned for subsequent calls.
- Specified by:
-
hashCode
in interfaceOpenMBeanConstructorInfo
- Overrides:
-
hashCode
in classObject
- Returns:
- the hash code value for this
OpenMBeanConstructorInfoSupport
instance - See Also:
-
Object.equals(java.lang.Object)
,System.identityHashCode(java.lang.Object)
toString
public String toString()
Returns a string representation of this
OpenMBeanConstructorInfoSupport
instance.
The string representation consists of the name of this class (ie
javax.management.openmbean.OpenMBeanConstructorInfoSupport
), the name and signature of the described constructor and the string representation of its descriptor.
As OpenMBeanConstructorInfoSupport
instances are immutable, the string representation for this instance is calculated once, on the first call to toString
, and then the same value is returned for subsequent calls.
- Specified by:
-
toString
in interfaceOpenMBeanConstructorInfo
- Overrides:
-
toString
in classObject
- Returns:
- a string representation of this
