Constructor Details

JOSEObjectJSON

protected JOSEObjectJSON(Payload payload)

Creates a new JOSE object with the specified payload.

Parameters:

payload - The payload, null if not available (e.g. for an encrypted JWE object).

Method Details

setPayload

protected void setPayload(Payload payload)

Sets the payload of this JOSE object.

Parameters:

payload - The payload, null if not available (e.g. for an encrypted JWE object).

getPayload

public Payload getPayload()

Returns the payload of this JOSE object.

Returns:

The payload, null if not available (for an encrypted JWE object that hasn't been decrypted).

toGeneralJSONObject

public abstract Map<String,Object> toGeneralJSONObject()

Returns a general JSON object representation of this JOSE secured object.

See JWS general serialisation or JWE general serialisation.

Returns:

The JSON object.

Throws:

IllegalStateException - If the JOSE object is not in a state that permits serialisation.

toFlattenedJSONObject

public abstract Map<String,Object> toFlattenedJSONObject()

Returns a flattened JSON object representation of this JOSE secured object. There must be exactly one JWS signature or JWE recipient for a flattened JSON serialisation.

See JWS flattened serialisation or JWE flattened serialisation.

Returns:

The JSON object.

Throws:

IllegalStateException - If the JOSE object is not in a state that permits serialisation or there is more than one JWS signature or JWE recipient.

serializeGeneral

public abstract String serializeGeneral()

Serialises this JOSE object to a general JOSE object string.

See JWS general serialisation or JWE general serialisation.

Returns:

The JSON object string.

Throws:

IllegalStateException - If the JOSE object is not in a state that permits serialisation.

serializeFlattened

public abstract String serializeFlattened()

Serialises this JOSE object to a flattened JSON object string. There must be exactly one JWS signature or JWE recipient for a flattened JSON serialisation.

See JWS flattened serialisation or JWE flattened serialisation.

Returns:

The JSON object string.

Throws:

IllegalStateException - If the JOSE object is not in a state that permits serialisation or there is more than one JWS signature or JWE recipient.

parse

public static JOSEObjectJSON parse(Map<String,Object> jsonObject)
                            throws ParseException

Parses a JOSE secured object from the specified JSON object representation.

Parameters:

jsonObject - The JSON object to parse. Must not be null.

Returns:

The corresponding JWSObjectJSON.

Throws:

ParseException - If the JSON object couldn't be parsed to a valid JWS or JWE secured object.

parse

public static JOSEObjectJSON parse(String json)
                            throws ParseException

Parses a JOSE secured object from the specified JSON string.

Parameters:

json - The JSON string to parse. Must not be null.

Returns:

The corresponding JWSObjectJSON.

Throws:

ParseException - If the string couldn't be parsed to a valid JWS or JWE secured object.
