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).

Since:

1.5

Method Summary

Modifier and Type	Method	Description
boolean	equals(Object obj)	Compares the specified obj parameter with this OpenMBeanConstructorInfo instance for equality.
String	getDescription()	Returns a human readable description of the constructor described by this OpenMBeanConstructorInfo instance.
String	getName()	Returns the name of the constructor described by this OpenMBeanConstructorInfo instance.
MBeanParameterInfo[]	getSignature()	Returns an array of OpenMBeanParameterInfo instances describing each parameter in the signature of the constructor described by this OpenMBeanConstructorInfo instance.
int	hashCode()	Returns the hash code value for this OpenMBeanConstructorInfo instance.
String	toString()	Returns a string representation of this OpenMBeanConstructorInfo instance.

Method Details

getDescription

String getDescription()

Returns a human readable description of the constructor described by this OpenMBeanConstructorInfo instance.

Returns:

the description.

getName

String getName()

Returns the name of the constructor described by this OpenMBeanConstructorInfo instance.

Returns:

the name.

getSignature

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

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.

Overrides:

equals in class Object

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.

See Also:

• Object.hashCode()
• HashMap

hashCode

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().

Overrides:

hashCode in class Object

Returns:

the hash code value for this OpenMBeanConstructorInfo instance

See Also:

• Object.equals(java.lang.Object)
• System.identityHashCode(java.lang.Object)

toString

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.

Overrides:

toString in class Object

Returns:

a string representation of this OpenMBeanConstructorInfo instance
