import javax.management.MBeanParameterInfo;
Describes a constructor of an Open MBean.
This interface declares the same methods as the class MBeanConstructorInfo
. A class implementing this interface (typically OpenMBeanConstructorInfoSupport
) should extend MBeanConstructorInfo
.
The getSignature()
method should return at runtime an array of instances of a subclass of MBeanParameterInfo
which implements the OpenMBeanParameterInfo
interface (typically OpenMBeanParameterInfoSupport
).
Since: 1.5

Compares the specified obj parameter with this OpenMBeanConstructorInfo
instance for equality. Returns true
if and only if all of the following statements are true:
- obj is non null,
- obj also implements the
OpenMBeanConstructorInfo
interface,
- their names are equal
- their signatures are equal.
This ensures that this equals
method works properly for obj parameters which are different implementations of the OpenMBeanConstructorInfo
interface.
Params: - obj – the object to be compared for equality with this
OpenMBeanConstructorInfo
instance;
Returns: true
if the specified object is equal to this OpenMBeanConstructorInfo
instance.

public boolean equals(Object obj);
Returns the hash code value for this OpenMBeanConstructorInfo
instance. The hash code of an OpenMBeanConstructorInfo
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 OpenMBeanConstructorInfo
instances t1
and t2
, as required by the general contract of the method Object.hashCode()
.
Returns: the hash code value for this OpenMBeanConstructorInfo
instance
