public interface TypeInfo
A representation of Java type, aiming at preserving more type information than what a Class can provide

Note: using null is not recommended, NONE should be used instead

      static final TypeInfo NONE

  • Method Details

    • asClass

      Class<?> asClass()
      Get the Class object represented by this TypeInfo. For a Type object, the TypeInfo object created from the Type object should return the exact same class as the one after Java erased its generic type info

    • param

      default TypeInfo param(int index)
      Example:

      1. for Map<String, Integer>, param(-1) == NONE, param(0) == STRING, param(1) == INT, param(2) == NONE

      2. for Map (raw usage of generic class) or Integer (not generic class), param(anyNumberHere) == NONE

      Returns:
      the actual type parameter at provided index, or NONE if:

      1. index not in valid range, or

      2. the TypeInfo itself is not representing a ParameterizedType

      true if this TypeInfo does NOT represent the same class as the Class parameter, false otherwise

    • shouldReplace

      default boolean shouldReplace()
      Returns:
