hashCode

public int hashCode()

Description copied from class: Object

Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)

Overrides:: hashCode in class Object

Returns:: a hash code value for this object.

Description copied from interface: Certificate

Indicates whether the key contained in this certificate may be used for the specified purpose.

Specified by:: queryKeyUsage in interface Certificate

Parameters:

purpose - A constant chosen from the KeyUsage constants indicating the purpose for which the key will be checked.

`KeyUsageResult.ALLOWED`	Thrown if the subject public key may be used for the specified purpose.
`KeyUsageResult.NOT_ALLOWED`	Thrown if the subject public key may not be used for the specified purpose.
