    Modifier and Type
    Method
    Description
    <R extends io.vena.bosk.StateTreeNode>
    org.bson.codecs.configuration.CodecProvider
    codecProviderFor(io.vena.bosk.Bosk<R> bosk)
    Note that the CodecProvider is Class-based, so it has anemic type information for generics due to type erasure.
    <T, R extends io.vena.bosk.StateTreeNode>
    org.bson.codecs.Codec<T>
    getCodec(Type targetType, Class<T> targetClass, org.bson.codecs.configuration.CodecRegistry registry, io.vena.bosk.Bosk<R> bosk)
    Like codecProviderFor(bosk).get(targetType, registry) except this works more broadly because it can accept a ParameterizedType for generic classes.

    • codecProviderFor

      public <R extends io.vena.bosk.StateTreeNode> org.bson.codecs.configuration.CodecProvider codecProviderFor(io.vena.bosk.Bosk<R> bosk)
      Note that the CodecProvider is Class-based, so it has anemic type information for generics due to type erasure. Because of this, the returned CodecProvider is unable to provide Codecs for certain generic types.

      In response to this shortcoming, you can access Codecs for any type using getCodec(Type, Class, CodecRegistry, Bosk)

    • getCodec

      public <T, R extends io.vena.bosk.StateTreeNode> org.bson.codecs.Codec<T> getCodec(Type targetType, Class<T> targetClass, org.bson.codecs.configuration.CodecRegistry registry, io.vena.bosk.Bosk<R> bosk)
      Like codecProviderFor(bosk).get(targetType, registry) except this works more broadly because it can accept a ParameterizedType for generic classes.
      Type Parameters:
      R - root type of bosk
      Parameters:
      targetClass - must match targetType. This is provided only to help Java do type inference and avoid ugly and unnecessary type casts.
