Detailed Description

template<typename T>
class MooseUtils::DelimitedFileReaderTempl< T >

Utility class for reading delimited data (e.g., CSV data).

Parameters

filename	A string for the filename to read.
comm	A pointer to a Communicator object (see below).

This class assumes that all data is numeric and can be converted to a C++ double. If a Communicator is provide then it will only read on processor 0 and broadcast the data to all processors. If not provided it will read on all processors.

IgnoreEmptyLines: When true all empty lines are ignored, when false an error is produced. FormatFlag: Set the file format (rows vs. columns). Delimiter: Set the file delimiter (if unset it will be detected). HeaderFlag: Set the header flag (TRUE used the first row has header, FALSE assumes no header, and AUTO will attempt to determine if a header exists). Comment: Set the comment character, by default no comment character is used.
