    • Method Detail

      • getDescription

        String getDescription()
        Returns a human readable description of the operation described by this OpenMBeanOperationInfo instance.
        Returns:
        the description.

      • getName

        String getName()
        Returns the name of the operation described by this OpenMBeanOperationInfo instance.
        Returns:
        the name.

      • getSignature

        MBeanParameterInfo[] getSignature()
        Returns an array of OpenMBeanParameterInfo instances describing each parameter in the signature of the operation described by this OpenMBeanOperationInfo instance. Each instance in the returned array should actually be a subclass of MBeanParameterInfo which implements the OpenMBeanParameterInfo interface (typically OpenMBeanParameterInfoSupport).
        Returns:
        the signature.

      • getReturnType

        String getReturnType()
        Returns the fully qualified Java class name of the values returned by the operation described by this OpenMBeanOperationInfo instance. This method should return the same value as a call to getReturnOpenType().getClassName().
        Returns:
        the return type.

      • getReturnOpenType

        OpenType<?> getReturnOpenType()
        Returns the open type of the values returned by the operation described by this OpenMBeanOperationInfo instance.
        Returns:
        the return type.

      • equals

        boolean equals​(Object obj)
        Compares the specified obj parameter with this OpenMBeanOperationInfo instance for equality.

        Returns true if and only if all of the following statements are true:

        • obj is non null,
        • obj also implements the OpenMBeanOperationInfo interface,
        • their names are equal
        • their signatures are equal
        • their return open types are equal
        • their impacts are equal
        This ensures that this equals method works properly for obj parameters which are different implementations of the OpenMBeanOperationInfo interface.
         
        Overrides:
        equals in class Object
        Parameters:
        obj - the object to be compared for equality with this OpenMBeanOperationInfo instance;
        Returns:
        true if the specified object is equal to this OpenMBeanOperationInfo instance.
        See Also:
        Object.hashCode(), HashMap

      • hashCode

        int hashCode()
        Returns the hash code value for this OpenMBeanOperationInfo instance.

        The hash code of an OpenMBeanOperationInfo instance is the sum of the hash codes of all elements of information used in equals comparisons (ie: its name, return open type, impact 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 OpenMBeanOperationInfo instances t1 and t2, as required by the general contract of the method Object.hashCode().

        Overrides:
        hashCode in class Object
        Returns:
        the hash code value for this OpenMBeanOperationInfo instance
        See Also:
        Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

      • toString

        String toString()
        Returns a string representation of this OpenMBeanOperationInfo instance.

        The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanOperationInfo), and the name, signature, return open type and impact of the described operation.

        Overrides:
        toString in class Object
        Returns:
        a string representation of this OpenMBeanOperationInfo instance
