Reference Manual

The MPL reference manual is an annotated formal specification of the library's public interface. The manual is available in two forms:

• A fully cross-referenced set of HTML pages.
• A cross-referenced, printer-ready PDFly, meaning that to filter a given character sequence the Filter typically must be invoked several times. OutputFilters represent a “push” model of filtering: a sequence of unfiltered characters and a Sink are provided, and the Filter is expected to filter the characters and write them to the Sink. Like InputFilters, OutputFilters also process data incrementally.

  The simplest InputFilters and OutputFilters process characters one at a time. This type of Filter is easy to write, but is less efficient than Filters that process several characters at a time. Filters which process several characters at a time are called Multi-Character fiters.

  Filter Helpers

  The Iostreams library provides several utilities to make Filter writing easier:
