public class MessageProp extends Object
When used with the GSSContext interface's wrap and getMIC methods, an instance of this class is used to indicate the desired Quality-of-Protection (QOP) and to request if confidentiality services are to be applied to caller supplied data (wrap only). To request default QOP, the value of 0 should be used for QOP.
When used with the unwrap and verifyMIC methods of the GSSContext interface, an instance of this class will be used to indicate the applied QOP and confidentiality services over the supplied message. In the case of verifyMIC, the confidentiality state will always be false
. Upon return from these methods, this object will also contain any supplementary status values applicable to the processed token. The supplementary status values can indicate old tokens, out of sequence tokens, gap tokens or duplicate tokens.

MessageProp |
Constructor which sets the desired privacy state. |
MessageProp |
Constructor which sets the values for the qop and privacy state. |
Modifier and Type | Method | Description |
---|---|---|
int |
getMinorStatus() |
Retrieves the minor status code that the underlying mechanism might have set for this per-message operation. |
String |
getMinorString() |
Retrieves a string explaining the minor status code. |
boolean |
getPrivacy() |
Retrieves the privacy state. |
int |
getQOP() |
Retrieves the QOP value. |
boolean |
isDuplicateToken() |
Tests if this is a duplicate of an earlier token. |
boolean |
isGapToken() |
Tests if an expected token was not received, i.e., one or more predecessor tokens have not yet been successfully processed. |
boolean |
isOldToken() |
Tests if this token's validity period has expired, i.e., the token is too old to be checked for duplication. |
boolean |
isUnseqToken() |
Tests if a later token had already been processed. |
void |
setPrivacy |
Sets the privacy state. |
void |
setQOP |
Sets the QOP value. |
void |
setSupplementaryStates |
This method sets the state for the supplementary information flags and the minor status in MessageProp. |
