mtkWWDMEvaluator-class: The mtkWWDMEvaluator class

Description

The mtkWWDMEvaluator class is a sub-class of the class mtkEvaluator used to manage the simulation of the model WWDM.

Class Hierarchy

Parent classes :

mtkEvaluator

Direct Known Subclasses :

Constructor

mtkWWDMEvaluator

signature(mtkParameters = NULL, listParameters = NULL)

Slots

name:

(character) always takes the string "evaluate".

protocol:

(character) a string to name the protocol used to run the process: http, system, R, etc. Here, it always takes the character "R".

site:

(character) a string to indicate where the service is located. Here, it always takes the string "mtk".

service:

(character) a string to name the service to invoke. Here, it always takes the string "WWDM".

parameters:

(vector) a vector of [mtkParameter] containing the parameters to pass while calling the service. The WWDM model does not need parameters.

ready:

(logical) a logical to tell if the process is ready to run.

state:

(logical) a logical to tell if the results produced by the process are available and ready to be consumed.

result:

(ANY) a data holder to hold the results produced by the process

Methods

setName

signature(this = "mtkWWDMEvaluator", name = "character"): Not used, method inherited from the parent class.

setParameters

signature(this = "mtkWWDMEvaluator", f = "vector"): Assigns new parameters to the process.

getParameters

signature(this = "mtkWWDMEvaluator"): Returns the parameters as a named list.

is.ready

signature( = "mtkWWDMEvaluator"): Tests if the process is ready to run.

setReady

signature(this = "mtkWWDMEvaluator", switch = "logical"): Makes the process ready to run.

is.ready

signature( = "mtkWWDMEvaluator"): Tests if the results produced by the process are available.

setReady

signature(this = "mtkWWDMEvaluator", switch = "logical"): Marks the process as already executed.

getResult

signature(this = "mtkWWDMEvaluator"): Returns the results produced by the process as a [mtkWWDMEvaluatorResult].

getData

signature(this = "mtkWWDMEvaluator"): Returns the results produced by the process as a data.frame.

serializeOn

signature(this = "mtkWWDMEvaluator"): Returns all data managed by the process as a named list.

run

signature(this = "mtkWWDMEvaluator", context= "mtkExpWorkflow"): runs the simulation.

summary

signature(object = "mtkWWDMEvaluator"): Provides a summary of the results produced by the process.

print

signature(x = "mtkWWDMEvaluator"): Prints a report of the results produced by the process.

plot

signature(x = "mtkWWDMEvaluator"): Plots the results produced by the process.

report

signature(this = "mtkWWDMEvaluator"): Reports the results produced by the process.
