Method Detail

equals

public boolean equals(Object object)

Compares the current object instance with another object instance.

Overrides:

equals in class Object

Parameters:

object - The object instance that the current object instance is to be compared with.

Returns:

True if the two object instances are equal, otherwise false.

hashCode

public int hashCode()

Description copied from class: Object

hashCode returns a hash code for this object. The hash code must be equal for two objects a and b if a.equals(b) is true.

The default implementation returns System.identityHashCode(this).

hashCode in class Object

Returns:

a hash code value.

getObjectName

public ObjectName getObjectName()

Returns the object name part.

Returns:

the object name.

getClassName

public String getClassName()

Returns the class part.

Returns:

the class name.

toString

public String toString()
