Method Detail

create

public static CredentialGenerator create(CredentialGenerator.ClassCode classCode)

A factory method to create a new instance of an CredentialGenerator for the given CredentialGenerator.ClassCode. Caller is supposed to invoke init() immediately after obtaining the instance.

Parameters:

classCode - the ClassCode of the CredentialGenerator implementation

Returns:

an instance of CredentialGenerator for the given class code

init

public void init()
          throws IllegalArgumentException

Initialize the credential generator.

Throws:

IllegalArgumentException - when there is a problem during initialization

initialize

protected abstract Properties initialize()
                                  throws IllegalArgumentException

Initialize the credential generator. This is provided separately from the init() method for convenience of implementations so that they do not need to store in sysProps. The latter is convenient for the users who do not need to store these properties rather can obtain it later by invoking getSystemProperties() Required to be implemented by concrete classes that implement this abstract class.

Returns:

A set of extra properties that should be added to Gemfire system properties when not null.

Throws:

IllegalArgumentException - when there is a problem during initialization

getSystemProperties

public Properties getSystemProperties()

Returns:

A set of extra properties that should be added to Gemfire system properties when not null.

getJavaProperties

public Properties getJavaProperties()

Returns:

A set of extra properties that should be added to Gemfire system properties when not null.

classCode

public abstract CredentialGenerator.ClassCode classCode()

The CredentialGenerator.ClassCode of this particular implementation.

Returns:

the ClassCode

getAuthInit

public abstract String getAuthInit()

The name of the AuthInitialize factory function that should be used in conjunction with the credentials generated by this generator.

Returns:

name of the AuthInitialize factory function

getAuthenticator

public abstract String getAuthenticator()

The name of the Authenticator factory function that should be used in conjunction with the credentials generated by this generator.

Returns:

name of the Authenticator factory function

getValidCredentials

public abstract Properties getValidCredentials(int index)

Get a set of valid credentials generated using the given index.

getValidCredentials

public abstract Properties getValidCredentials(Principal principal)

Get a set of valid credentials for the given Principal.

Returns:

credentials for the given Principal or null if none possible.

getInvalidCredentials

public abstract Properties getInvalidCredentials(int index)

Get a set of invalid credentials generated using the given index.
