Interface OpenMBeanConstructorInfo

All Known Implementing Classes:
OpenMBeanConstructorInfoSupport
public interface OpenMBeanConstructorInfo

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).

          Returns the hash code value for this OpenMBeanConstructorInfo instance.
 String toString()
          Returns a string representation of this OpenMBeanConstructorInfo instance.
 

Method Detail

getDescription

public String getDescription()
Returns a human readable description of the constructor described by this OpenMBeanConstructorInfo instance.

Returns:
the description.

getName

public String getName()
Returns the name of the constructor described by this OpenMBeanConstructorInfo instance.

Returns:
the name.

getSignature

public MBeanParameterInfo[] getSignature()
Returns an array of OpenMBeanParameterInfo instances describing each parameter in the signature of the constructor described by this OpenMBeanConstructorInfo instance.

Returns:
the signature.

equals

public boolean equals(Object obj)
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.
 

Parameters:
obj - the object to be compared for equality with this OpenMBeanConstructorInfo instance;
Returns:
true if the specified object is equal to this OpenMBeanConstructorInfo instance.

hashCode

public int hashCode()
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

toString

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

The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanConstructorInfo), and the name and signature of the described constructor.

Returns:
a string representation of this OpenMBeanConstructorInfo instance
