public class YamlTokenizer
extends AbstractYamlProcessor<YamlTokenizer>

Processes raw YAML source text into a stream of YamlToken objects.This tokenizer implements a stateful scan that tracks indentation levels to produce structural tokens (INDENT, DEDENT) alongside standard YAML indicators and scalars.

Indentation Rules

• Only spaces are permitted for indentation.
• Tabs encountered in a whitespace context will trigger a RuntimeException.
• A DEDENT must return exactly to a previously established indentation column.

Scalar Constraints

• Plain scalars (unquoted) cannot contain a colon (:) unless it is a valid value indicator followed by whitespace.
