SmartFrogAssertionException - error in verification

SmartFrogException - error in verification

assertTrue

protected void assertTrue(boolean fact,
                          java.lang.String test)
                   throws SmartFrogAssertionException

make an assertion

Parameters:

fact - result flag

test - test String

Throws:

SmartFrogAssertionException - error in assertion

evaluate

public boolean evaluate(java.lang.Object target,
                        java.lang.String methodName)
                 throws SmartFrogException,
                        java.rmi.RemoteException

evaluate a named method on an object; expect it to return a boolean

Parameters:

target - object to invoke

methodName - name of method

Returns:

the boolean value of the invocation

Throws:

SmartFrogException - error in evaluation

java.rmi.RemoteException - In case of network/rmi error

sfPing

public void sfPing(java.lang.Object source)
            throws SmartFrogLivenessException,
                   java.rmi.RemoteException

Liveness call in to check if this component is still alive.

Specified by:

sfPing in interface Liveness

Overrides:

sfPing in class PrimImpl

Parameters:

source - source of call

Throws:

SmartFrogLivenessException - component is terminated

java.rmi.RemoteException - In case of network/rmi error

sfDeploy

public void sfDeploy()
              throws SmartFrogException,
                     java.rmi.RemoteException

Called after instantiation for deployment purposed. Heart monitor is started and if there is a parent the deployed component is added to the heartbeat. Subclasses can override to provide additional deployment behavior.

Specified by:

sfDeploy in interface Prim

Overrides:

sfDeploy in class PrimImpl

Can be called to start components. Subclasses should override to provide functionality Do not block in this call, but spawn off any main loops!

Specified by:

sfStart in interface Prim

Overrides:

sfStart in class PrimImpl

Throws:

SmartFrogException - failure while starting

java.rmi.RemoteException - In case of network/rmi error
