An object encapsulating basic character constants.

A character array reader reads a stream of characters (keeping track of their positions) from an array.

Undefined position.

OffsetPosition is a standard class for positions represented as offsets into a source document.

An object holding the index cache.

The PagedSeq object defines a lazy implementations of a random access sequence.

Provides utility methods that return instances of PagedSeq[Char]. fromIterator and fromIterable provide generalised instances of PagedSeq

An implementation of lazily computed sequences, where elements are stored in "pages", i.e. arrays of fixed size.

A paged sequence is constructed from a function that produces more elements when asked. The producer function - more, is similar to the read method in java.io.Reader. The more function takes three parameters: an array of elements, a start index, and an end index. It should try to fill the array between start and end indices (excluding end index). It returns the number of elements produced, or -1 if end of logical input stream was reached before reading any element.

Position is the base trait for objects describing a position in a document.

It provides functionality for:

• generating a visual representation of this position (longString);
• comparing two positions (<).

To use this class for a concrete kind of document, implement the lineContents method.

A trait for objects that have a source position.

An interface for streams of values that have positions.

An object to create a StreamReader from a java.io.Reader.

A StreamReader reads from a character sequence, typically created as a PagedSeq from a java.io.Reader

NOTE: StreamReaders do not really fulfill the new contract for readers, which requires a source CharSequence representing the full input. Instead source is treated line by line. As a consequence, regex matching cannot extend beyond a single line when a StreamReader are used for input.

If you need to match regexes spanning several lines you should consider class PagedSeqReader instead.
