public class OpenMBeanConstructorInfoSupport
extends MBeanConstructorInfo
implements OpenMBeanConstructorInfo

Describes a constructor of an Open MBean.

OpenMBeanConstructorInfoSupport

public OpenMBeanConstructorInfoSupport(String name,
                                       String description,
                                       OpenMBeanParameterInfo[] signature)

Constructs an {@code OpenMBeanConstructorInfoSupport} instance, which describes the constructor of a class of open MBeans with the specified {@code name}, {@code description} and {@code signature}.

The {@code signature} array parameter is internally copied, so that subsequent changes to the array referenced by {@code 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.

OpenMBeanConstructorInfoSupport

public OpenMBeanConstructorInfoSupport(String name,
                                       String description,
                                       OpenMBeanParameterInfo[] signature,
                                       Descriptor descriptor)

Constructs an {@code OpenMBeanConstructorInfoSupport} instance, which describes the constructor of a class of open MBeans with the specified {@code name}, {@code description}, {@code signature}, and {@code descriptor}.

The {@code signature} array parameter is internally copied, so that subsequent changes to the array referenced by {@code 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.

equals

public boolean equals(Object obj)

Compares the specified {@code obj} parameter with this {@code OpenMBeanConstructorInfoSupport} instance for equality.

Returns {@code true} if and only if all of the following statements are true:

• {@code obj} is non null,
• {@code obj} also implements the {@code OpenMBeanConstructorInfo} interface,
• their names are equal
• their signatures are equal.

This ensures that this {@code equals} method works properly for {@code obj} parameters which are different implementations of the {@code OpenMBeanConstructorInfo} interface.

Overrides:

equals in class MBeanConstructorInfo

Parameters:

obj - the object to be compared for equality with this {@code OpenMBeanConstructorInfoSupport} instance;

Returns:

{@code true} if the specified object is equal to this {@code OpenMBeanConstructorInfoSupport} instance.

hashCode

public int hashCode()

Returns the hash code value for this {@code OpenMBeanConstructorInfoSupport} instance.

The hash code of an {@code OpenMBeanConstructorInfoSupport} instance is the sum of the hash codes of all elements of information used in {@code equals} comparisons (ie: its name and signature, where the signature hashCode is calculated by a call to {@code java.util.Arrays.asList(this.getSignature).hashCode()}).

This ensures that {@code t1.equals(t2)} implies that {@code t1.hashCode()==t2.hashCode()} for any two {@code OpenMBeanConstructorInfoSupport} instances {@code t1} and {@code t2}, as required by the general contract of the method {@link Object#hashCode() Object.hashCode()}.

However, note that another instance of a class implementing the {@code OpenMBeanConstructorInfo} interface may be equal to this {@code OpenMBeanConstructorInfoSupport} instance as defined by {@link #equals(java.lang.Object)}, but may have a different hash code if it is calculated differently.

As {@code OpenMBeanConstructorInfoSupport} instances are immutable, the hash code for this instance is calculated once, on the first call to {@code hashCode}, and then the same value is returned for subsequent calls.

Overrides:

hashCode in class MBeanConstructorInfo

Returns:

the hash code value for this {@code OpenMBeanConstructorInfoSupport} instance

toString

public String toString()

Returns a string representation of this {@code OpenMBeanConstructorInfoSupport} instance.

The string representation consists of the name of this class (ie {@code javax.management.openmbean.OpenMBeanConstructorInfoSupport}), the name and signature of the described constructor and the string representation of its descriptor.

As {@code OpenMBeanConstructorInfoSupport} instances are immutable, the string representation for this instance is calculated once, on the first call to {@code toString}, and then the same value is returned for subsequent calls.

Overrides:

toString in class MBeanConstructorInfo

Returns:

a string representation of this {@code OpenMBeanConstructorInfoSupport} instance
