extract

public void extract(com.mapr.db.rowcol.DBDocumentImpl doc,
                    int iRow)

Description copied from class: ValueExtractor

Extract the specified value from the ValueVector, and add it to the document with the fieldName specified at construction time. If the value is NULL (which must be checked for a NullableValueVector), this should do nothing.

Specified by:

extract in class ValueExtractor

Parameters:

doc - the document to add the field-value pair to

iRow - the index into the value vector; note this has already been checked against ValueExtractor.valueCount, so there's no need to check it here.
