List of addImplicitResolver() Examples

Examples of addImplicitResolver()

org.yaml.snakeyaml.Yaml.addImplicitResolver()
Add an implicit scalar detector. If an implicit scalar value matches the given regexp, the corresponding tag is assigned to the scalar. @deprecated use Tag instead of String @param tag tag to assign to the node @param regexp regular expression to match against @param first a sequence of possible initial characters or null (which means any).
