Context

public Context()

Instantiates empty context object

Context

public Context(javax.security.auth.Subject subject)
        throws ContextException

subject - Subject to create context from

Throws:

ContextException

Context

public Context(java.lang.String string)
        throws ContextException

Instantiates context object containing claims from a string

Parameters:

stringBuffer - String buffer to create context from

Throws:

ContextException

Method Detail

toSubject

public boolean toSubject(javax.security.auth.Subject subject)

Saves context as a private credential in Subject

Parameters:

subject - Subject to save context to

Returns:

true if the subject did not already contain the context; false otherwise in which case the context was not saved

showContents

public java.lang.String showContents()

For debugging purposes, dump all available claims to a String

Returns:

String containing all claims in the context

toString

public java.lang.String toString()

Convert context to a String representation in a way that can be used to instantiate Context from a String

Overrides:

toString in class java.lang.Object

Returns:

String containing serialized claims in the context

getDictionary

public static ClaimDictionary getDictionary()

Return context dictionary

Returns:

Context dictionary

getSize

public int getSize()

Return number of claims in the context

Returns:

Number of claims in the context

hasClaim

public boolean hasClaim(java.lang.String name)

Validate if a given claim exists in the context

Parameters:

name - Name of the claim

Returns:

true if the claim exists in the context

getClaim

public Claim getClaim(java.lang.String name)
               throws UnknownClaimException

Return requested claim

Parameters:

name - Name of the claim

Returns:

Requested claim

Throws:

UnknownClaimException

isValidClaim

public boolean isValidClaim(java.lang.String name,
                            java.lang.String value)

Validate a claim with the given name and value is legitimate. This method doesn't return the reason for why a claim may be invalid. If its necessary to know why a claim is invalid, instantiate Claim (name, value) and catch the exception.

Parameters:

name - Name of the claim

value - Value of the claim

addClaim

public void addClaim(java.lang.String name,
                     java.lang.String value,

              throws ContextException,
                     UnknownClaimException,
                     DuplicateClaimException

Populate context with a new claim created from the specified name and value, using dictionary associated with this context.

Parameters:

name - Name of the claim

value - Value of the claim

overwrite - If true, indicates that an existing claim with identical name should be overwritten

Throws:

ContextException

UnknownClaimException

DuplicateClaimException

addClaim

public void addClaim(SAMLAttribute samlAttr,
                     boolean overwrite)
              throws ContextException,
