Constructor Detail

ManualDiscretization

public ManualDiscretization()

Method Detail

load

public void load(Step st)
          throws M4CompilerError

Simply calls its superclass load method.

Overrides:

load in class FeatureConstruction

Parameters:

st - the step this operator is applied in

Throws:

M4CompilerError

getCurrentLoopNumber

public int getCurrentLoopNumber()

The operators Time/NumericalIntervalManualDiscretisation are not loopable any longer. Therefore the method getCurrentLoopNumber() is overwritten.

Overrides:

getCurrentLoopNumber in class FeatureConstruction

Returns:

0

getDefaultValue

public Value getDefaultValue()
                      throws M4CompilerError

Throws:

M4CompilerError

getIntervalStart

public Value[] getIntervalStart()
                         throws M4CompilerError

The parameter IntervalStart is coordinated.

Throws:

M4CompilerError

getIntervalEnd

public Value[] getIntervalEnd()
                       throws M4CompilerError

The parameter IntervalEnd is coordinated.

Throws:

M4CompilerError

getMapTo

public Value[] getMapTo()
                 throws M4CompilerError

The parameter MapTo is coordinated.

Throws:

M4CompilerError

getStartIncExc

public Value[] getStartIncExc()
                       throws M4CompilerError

The parameter StartIncExc is coordinated.

Throws:

M4CompilerError

getEndIncExc

public Value[] getEndIncExc()
                     throws M4CompilerError

The parameter EndIncExc is coordinated.

Throws:

M4CompilerError

generateSQL

public abstract java.lang.String generateSQL(Column theTargetAttributeColumn)
                                      throws M4CompilerError

Generates a sql-function to describe a new column. This method generates a sql-function to describe a new column. It is implemented in its subclasses

Specified by:

generateSQL in class Discretization

Parameters:

theTargetAttributeColumn - The Column to which this FeatureConstruction Operator is applied. Some subclasses may ignore this parameter.

Returns:

the SQL-function call

Throws:

M4CompilerError - A simple exception object with an error message.

getDiscTableName

protected java.lang.String getDiscTableName()

getSmaller

protected java.lang.String getSmaller(int intervalNumber,
                                      boolean start)
                               throws M4CompilerError

Throws:

M4CompilerError

getGreater

protected java.lang.String getGreater(int intervalNumber,
                                      boolean start)
                               throws M4CompilerError

Throws:

M4CompilerError
