Method Detail

generate

public static DESIViewModel generate(InputData input,
                                     PropertyInitializer prop_init)
                              throws NoValidDeploymentException

This method generates a new System based on the parameters it is given as input. However, if any of these paramters are invalid, this method will return null.

Parameters:

input -

prop_init - PropertyInitializer - In order to create a new model, we need to know what properties are being used.

Returns:

DESIViewModel a newly generated system or null if the paremeters are incorrect.

Throws:

NoValidDeploymentException

checkComponentsFit

public static void checkComponentsFit(DESIViewModel model)
                               throws NoValidDeploymentException

This is a utility method that can be used to make sure that the components fit on their hosts (memory-wise).

Parameters:

model - DESIDataModel - The model object.

Throws:

NoValidDeploymentException - Thrown if the components do not fit on the hosts.

checkComponentsFit

public static void checkComponentsFit(DESIDataModel model)
                               throws NoValidDeploymentException

Throws:

NoValidDeploymentException

generateInRange

private static java.lang.Object generateInRange(java.lang.String max,
                                                java.lang.String min,
                                                java.lang.String type,
                                                java.util.Random rand)

This method generates a random number between min and max of the given type and returns it as one of the primitive wrappers. You must also pass it a Random class just so that it doesn't have to create its own.

Parameters:

max -

min -

type -

rand -

Returns:
