Class Inheritance
All Implemented Interfaces
com.univocity.parsers.common.processor.RowProcessor, com.univocity.parsers.common.processor.core.Processor
Imports
com.univocity.parsers.common.*, com.univocity.parsers.common.processor.core.*
A simple RowProcessor implementation that stores values of columns. Values parsed in each row will be split into columns of Strings. Each column has its own list of values.

At the end of the process, the user can access the lists with values parsed for all columns using the methods getColumnValuesAsList(), getColumnValuesAsMapOfIndexes() and getColumnValuesAsMapOfNames().

Note

Storing the values of all columns may be memory intensive. For large inputs, use a BatchedColumnProcessor instead
