Method Detail

generateSQL

public 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. Also creates a discretization table.

Specified by:

generateSQL in class ManualDiscretization

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.
