ConsentManager and Consent contracts

Library provides functionality to create new consents on noordung blockchain.

get consent manager

let CM = await fd.getConsentManager(); let tx = await CM.createConsent(userAddress, subjectAddress, "0x" + swarmHash);

Get existing consents where account is user

let uc = await CM.getUserConsents();

Get existing consents where account is subject

let sc = await CM.getSubjectConsents();

Get consents for swarmHash

let cf = await CM.getConsentsFor("0x" + swarmHash);

Get consent from address

let consent = await fd.getConsent(address);

Sign last user consent as user

let us = await consent.isUserSigned(); await consent.signUser();

Sign last user consent as subject

let ss = await consent.isSubjectSigned(); await consent.signSubject();

Update consent with new location

let tx = await CM.updateConsent(consent, "0x" + newSwarmHash);

Updating consent will revoke updated one, and create new one. Old one will have property updatedConsent changed from 0x0000000000000000000000000000000000000000

Getting info on updated consents

If updated anything else than address(0x0) then consent was updated with another consent updated = await consent.isUpdatedWith(); updated will contain address of updated consent

Checking signatures

us = await consent.isUserSigned(); ss = await consent.isSubjectSigned(); s = await consent.isSigned(); v = await consent.isValid();

Checking consent status

status = await consent.status(); Status values: 0 - waiting for signatures 1 - active 2 - expired 3 - revoked
