  +--librarian.ppProcessor

public class ppProcessor

extends java.lang.Object

The class collects several tools used when pre- or postprocessing a LEA move. It contains information about:

• The test data supplied in TestDatum moves.
• The history of previous outputs used with pidgin
• The labels in the program
• The random number generator in use
• The current librarian

Method Detail

historyLookup

public int historyLookup(int typeIndex,
                         int back)
                  throws InternalException,
                         DesignException

Looks up the EuLab index of a previous output of type typeIndex. The number back determines how much back in time to go, progressing 0 (previous), 1 (penultimate), etc, up to PIDGIN_MINUS_MAX.

Parameters:

typeIndex - index of object type

back - how much back in time to go

Returns:

the index

Throws:

InternalException - if back too small or large

DesignException - if no such history available

labelLookup

public interagents.wrapItemBlock labelLookup(java.lang.String label)

addLabel

public void addLabel(interagents.wrapItemBlock wib,
                     java.lang.String label)

updateHistory

public void updateHistory(interagents.finalWrapper out)

Update history with the data in the supplied wrapper

Parameters:

out - recent output with which to update

chooseTestDataLine

public void chooseTestDataLine(int line)
                        throws DesignException

Chooses a line of test data, checking if existant if line>0

Parameters:

line - indexed from 0 and up

Throws:

DesignException - if no such line

getTestDataLine

public fundamentals.EuArguments getTestDataLine()
                                         throws DesignException

DesignException

getTestDatum

public double getTestDatum(int n)
                    throws DesignException

Parameters:

n - the number of the datum, indexed from 0 and up

Returns:

a test datum from current line of test data

Throws:

DesignException - if no such datum

readTestData

public void readTestData(fundamentals.EuArguments args)
                  throws DesignException,
                         InternalException

Read arguments from a TestDatum command into the test database.

Parameters:

args - arguments to pass

Throws:

DesignException - if argument lenghts are varying

InternalException
