    All Known Implementing Classes:

    public interface CoreMap
extends TypesafeMap, PrettyLoggable, Serializable
    Base type for all annotatable core objects. Should usually be instantiated as ArrayCoreMap. Many common key definitions live in CoreAnnotations, but others may be defined elsewhere. See CoreAnnotations for details. Note that implementations of this interface must take care to implement equality correctly: by default, two CoreMaps are .equal if they contain the same keys and all corresponding values are .equal. Subclasses that wish to change this behavior (such as HashableCoreMap) must make sure that all other CoreMap implementations have a special case in their .equals to use that equality definition when appropriate. Similarly, care must be taken when defining hashcodes. The default hashcode is 37 * sum of all keys' hashcodes plus the sum of all values' hashcodes. However, use of this class as HashMap keys is discouraged because the hashcode can change over time. Consider using a HashableCoreMap.

    • Method Detail

      • toShorterString

        String toShorterString​(String... what)
        Attempt to provide a briefer and more human readable String for the contents of a CoreMap. The method may not be capable of printing circular dependencies in CoreMaps.
        Parameters:
        what - An array (varargs) of Strings that say what annotation keys to print. These need to be provided in a shortened form where you are just giving the part of the class name without package and up to "Annotation". That is, edu.stanford.nlp.ling.CoreAnnotations.PartOfSpeechAnnotation ➔ PartOfSpeech . As a special case, an empty array means to print everything, not nothing.
        Returns:
        A more human readable String giving possibly partial contents of a CoreMap.
