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

object defines a lazy implementations of
a random access sequence.

- class
An implementation of lazily computed sequences, where elements are stored in "pages", i.e. arrays of fixed size.
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.
- Type parameters:
- T
the type of the elements contained in this paged sequence, with an
ClassTag
context bound.

Position
is the base trait for objects describing a position in a document
.
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.
A trait for objects that have a source position.
An interface for streams of values that have positions.
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
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.
