Method Detail

isMandatory

public boolean isMandatory()
Get the MessagePolicy modifier.

Returns:
A boolean indicating whether the MessagePolicy is optional(false) or required(true).

getTargetPolicies

public MessagePolicy.TargetPolicy[] getTargetPolicies()
Get the target policies that comprise the authentication policy.

Returns:
An array of target authentication policies, where each element describes an authentication policy and the parts of the message to which the authentication policy applies. This method returns null to indicate that no security operations should be performed on the messages to which the policy applies. This method never returns a zero-length array.

When this method returns an array of target policies, the order of elements in the array represents the order that the corresponding message transformations or validations described by the target policies are to be performed by the authentication module.
