The abstract base class for operations that can be applied by TextRewriterTransform .Signature:
export declare abstract class TextRewriter
The TextRewriterTransform applies one or more character rewriting operations to its chunk stream. Since these operations are applied separately to
stdout , the state is stored in an opaque
TextRewriter subclass is very similar to a regular expression, with the difference that
RegExp operates on a text string, whereas
TextRewriter operates on a stream of characters.
A rewriting operation starts with
initialize() , followed by any number of
process() calls, and then finishes with
close() . For example:
const rewriter: NormalizeNewlinesTextRewriter = new NormalizeNewlinesTextRewriter(NewlineKind.Lf);
const state: TextRewriterState = rewriter.initialize();
let output: string = rewriter.process(state, 'line 1\r');
output += rewriter.process(state, '\nline 2\r\n');
output += rewriter.close(state);
// The final "output" value is: "line 1\nline 2\n"
close() has been called, the
TextRewriterState state should not be reused.
|close(state)||Close the |
|initialize()||Create a new |
|process(state, input)||Rewrite the next sequence of characters from the input stream, returning the modified output.|
