SummarizerBase

SummarizerBase performs work shared by all sumarizers, most everything except for handling of unique keys.

The base class handles creation, allocates storage for Operators and SharedFieldValues, and similar. Derived classes deal primarily with unique keys and the associated Calculators and UniqueKeyValuesLists.

inputFieldDelimiter char inputFieldDelimiter(): Undocumented in source. Be warned that the author may not have intended to support it.
makeUniqueKeyValuesLists UniqueKeyValuesLists makeUniqueKeyValuesLists(): Undocumented in source. Be warned that the author may not have intended to support it.
processHeaderLine bool processHeaderLine(char[][] lineFields): Called to process the header line of each file. Returns true if it was the first header line processed (used when reading multiple files).
processNextLine void processNextLine(char[][] lineFields): Undocumented in source.
setOperators void setOperators(InputRange!Operator operators): Sets the Operators used by the Summarizer. Called after construction.
writeSummaryBody void writeSummaryBody(OutputRange outputStream, SummarizerPrintOptions ): Undocumented in source.
