Method Detail

getParameterSpec

public final AlgorithmParameterSpec getParameterSpec()

Class is disabled.

Description copied from interface: AlgorithmMethod

Returns the algorithm parameters of this AlgorithmMethod.

Specified by:

getParameterSpec in interface AlgorithmMethod

Specified by:

getParameterSpec in interface DigestMethod

Returns:

the algorithm parameters of this AlgorithmMethod. Returns null if this AlgorithmMethod does not require parameters and they are not specified.

marshal

public void marshal(org.w3c.dom.Node parent,
                    String prefix,
                    DOMCryptoContext context)
             throws MarshalException

Class is disabled.

This method invokes the abstract marshalParams method to marshal any algorithm-specific parameters.

Specified by:

marshal in class DOMStructure

Throws:

MarshalException

equals

public boolean equals(Object o)

Enabled. assumes no non-deterministic equals methods in libraries

Description copied from class: Object

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Overrides:

equals in class Object

Parameters:

o - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.
