public class SSFileEnvironment extends java.lang.Object implements Environment
This is the base class for all the single step problems environments that read the examples from a file. It uses the Dataset API to get all the information needed from the file.

public SSFileEnvironment(java.lang.String fileName,
boolean readAttrBounds)
It's the constructor of the class.
fileName - is the name of the file where
the attributes of the problem are described.readAttrBounds - is the name of the file where the
examples of the execution are written.public boolean wasCorrect()
Does determine if the classification was good
wasCorrect in interface Environmentpublic double makeAction(int action)
This function returns the reward given at applying the action in the environment.
makeAction in interface Environmentaction - is the action chosen to do.
* @return a double with the rewardpublic double[] getCurrentState()
The function returns the current state.
getCurrentState in interface Environmentpublic double[] newState()
Does create a new state of the problem. The XCS have to decide the action to do.
newState in interface Environmentpublic double getMaxPayoff()
Does return the environment maximum payoff
getMaxPayoff in interface Environmentpublic double getMinPayoff()
Does return the environment minimum payoff
getMinPayoff in interface Environmentpublic boolean isPerformed()
Does return if the class has been executed. It is used in the multiple step problems.
isPerformed in interface Environmentpublic int getEnvironmentClass()
Does return if the class of the environmental state. It's used by the UCS.
getEnvironmentClass in interface Environmentpublic void beginSequentialExamples()
It initializes at the first example. It is used in the file environment to get the examples sequentially.
beginSequentialExamples in interface Environmentpublic double[] getSequentialState()
It returns the new Example of a single step file environment.
getSequentialState in interface Environmentpublic int getNumberOfExamples()
It return the number of the examples of the database. It's only used in the file environments.
getNumberOfExamples in interface Environmentpublic void deleteMatchedExamples(Classifier cl)
It deletes the examples of the database that match with de classifier passed. It's only used in the file enviornment.
deleteMatchedExamples in interface Environmentcl - is the classifier which if the examples matches with,
the have to be eliminate from the set.
