Class UnicodeDataTemplateController

  • public abstract class UnicodeDataTemplateController
extends java.lang.Object
    StringTemplate controller used to generate parameters to feed to unicodedata.st to code-generate UnicodeData.java, used by the tool for Unicode property escapes like \\p\{Lu\}. Uses ICU to iterate over Unicode character categories, properties, and script codes, as well as aliases for those codes. This class exists in its own Maven module to avoid adding a dependency from the tool onto the (large) ICU runtime.
