CredentialParams class

Contains credentials to authenticate against external services. They are used together with connection parameters, but usually stored in a separate store, protected from unauthorized access.

Configuration parameters

store_key: key to retrieve parameters from credential store
username: user name
user: alternative to username
password: user password
pass: alternative to password
access_id: application access id
client_id: alternative to access_id
access_key: application secret key
client_key: alternative to access_key
secret_key: alternative to access_key

In addition to standard parameters CredentialParams may contain any number of custom parameters

Example

var credential = CredentialParams.fromTuples(
    'user', 'jdoe',
    'pass', 'pass123',
    'pin', '321'
);

var username = credential.getUsername();             // Result: 'jdoe'
var password = credential.getPassword();             // Result: 'pass123'
var pin = credential.getAsNullableString('pin');     // Result: 321
