Method Detail

normalizedSize

int normalizedSize(ColumnDefinition colDef,
                 boolean isInput)

Calculate how many elements a column will normalize into.

Parameters:

colDef - The column definition.

isInput - True, if this is an input column.

Returns:

The number of elements needed to normalize this column.

normalizeColumn

int normalizeColumn(ColumnDefinition colDef,
                  boolean isInput,
                  String value,
                  double[] outpuData,
                  int outputColumn)

Normalize a column, with a string input.

Parameters:

colDef - The column definition.

isInput - True, if this is an input column.

value - The value to normalize.

outpuData - The output data.

outputColumn - The element to begin outputing to.

Returns:

The new output element, advanced by the correct amount.

denormalizeColumn

String denormalizeColumn(ColumnDefinition colDef,
                       boolean isInput,
                       MLData output,
                       int idx)

Normalize a column, with a double input.

Parameters:

colDef - The column definition.

isInput - True, if this is an input column.

value - The value to normalize.

outpuData - The output data.

outputColumn - The element to begin outputing to.

Returns:

The new output element, advanced by the correct amount.

normalizeColumn

int normalizeColumn(ColumnDefinition colDef,
                  boolean isInput,
                  double value,
                  double[] outpuData,
                  int outputColumn)

Normalize a column, with a double value.

Parameters:

colDef - The column definition.

isInput - True, if this is an input column.

value - The value to normalize.

outpuData - The output data.

outputColumn - The element to begin outputing to.

Returns:

The new output element, advanced by the correct amount.
