The Parser, on the contrary, - * is a straightforward implementation of a recursive-descendant parser (or, - * LL(1) parser, as it is usually called). - * - * Actually there are two issues of Scanning that might be called "clever", the - * rest is quite straightforward. The issues are "block collection start" and - * "simple keys". Both issues are explained below in details. - * - * Here the Scanning step is explained and implemented. We start with the list - * of all the tokens produced by the Scanner together with short descriptions. - * - * Now, tokens: - * - * STREAM-START(encoding) # The stream start. - * STREAM-END # The stream end. - * VERSION-DIRECTIVE(major,minor) # The '%YAML' directive. - * TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive. - * DOCUMENT-START # '---' - * DOCUMENT-END # '...' - * BLOCK-SEQUENCE-START # Indentation increase denoting a block - * BLOCK-MAPPING-START # sequence or a block mapping. - * BLOCK-END # Indentation decrease. - * FLOW-SEQUENCE-START # '[' - * FLOW-SEQUENCE-END # ']' - * BLOCK-SEQUENCE-START # '{' - * BLOCK-SEQUENCE-END # '}' - * BLOCK-ENTRY # '-' - * FLOW-ENTRY # ',' - * KEY # '?' or nothing (simple keys). - * VALUE # ':' - * ALIAS(anchor) # '*anchor' - * ANCHOR(anchor) # '&anchor' - * TAG(handle,suffix) # '!handle!suffix' - * SCALAR(value,style) # A scalar. - * - * The following two tokens are "virtual" tokens denoting the beginning and the - * end of the stream: - * - * STREAM-START(encoding) - * STREAM-END - * - * We pass the information about the input stream encoding with the - * STREAM-START token. - * - * The next two tokens are responsible for tags: - * - * VERSION-DIRECTIVE(major,minor) - * TAG-DIRECTIVE(handle,prefix) - * - * Example: - * - * %YAML 1.1 - * %TAG ! !foo - * %TAG !yaml! tag:yaml.org,2002: - * --- - * - * The correspoding sequence of tokens: - * - * STREAM-START(utf-8) - * VERSION-DIRECTIVE(1,1) - * TAG-DIRECTIVE("!","!foo") - * TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:") - * DOCUMENT-START - * STREAM-END - * - * Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole - * line. - * - * The document start and end indicators are represented by: - * - * DOCUMENT-START - * DOCUMENT-END - * - * Note that if a YAML stream contains an implicit document (without '---' - * and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be - * produced. - * - * In the following examples, we present whole documents together with the - * produced tokens. - * - * 1.

The following tokens are - * used to describe aliases, anchors, tag, and scalars: - * - * ALIAS(anchor) - * ANCHOR(anchor) - * TAG(handle,suffix) - * SCALAR(value,style) - * - * The following series of examples illustrate the usage of these tokens: - * - * 1. A recursive sequence: - * - * &A [ *A ] - * - * Tokens: - * - * STREAM-START(utf-8) - * ANCHOR("A") - * FLOW-SEQUENCE-START - * ALIAS("A") - * FLOW-SEQUENCE-END - * STREAM-END - * - * 2.
