      Modifier and Type Method Description
      java.lang.Object asKey​(java.lang.Class<?> rawBase)
      Factory method that will create an object that can be used as a key for caching purposes by TypeFactory
      static TypeBindings create​(java.lang.Class<?> erasedType, JavaType typeArg1)  
      static TypeBindings create​(java.lang.Class<?> erasedType, JavaType[] types)  
      static TypeBindings create​(java.lang.Class<?> erasedType, JavaType typeArg1, JavaType typeArg2)  
      static TypeBindings create​(java.lang.Class<?> erasedType, java.util.List<JavaType> typeList)
      Factory method for constructing bindings for given class using specified type parameters.
      static TypeBindings create​(java.util.List<java.lang.String> names, java.util.List<JavaType> types)
      Factory method for constructing bindings given names and associated types.
      static TypeBindings createIfNeeded​(java.lang.Class<?> erasedType, JavaType typeArg1)
      Alternate factory method that may be called if it is possible that type does or does not require type parameters; this is mostly useful for collection- and map-like types.
      static TypeBindings createIfNeeded​(java.lang.Class<?> erasedType, JavaType[] types)
      Alternate factory method that may be called if it is possible that type does or does not require type parameters; this is mostly useful for collection- and map-like types.
      static TypeBindings emptyBindings()  
      boolean equals​(java.lang.Object o)  
      JavaType findBoundType​(java.lang.String name)
      Find type bound to specified name, if there is one; returns bound type if so, null if not.
      java.lang.String getBoundName​(int index)  
      JavaType getBoundType​(int index)  
      java.util.List<JavaType> getTypeParameters()
      Accessor for getting bound types in declaration order
      int hashCode()  
      boolean hasUnbound​(java.lang.String name)  
      boolean isEmpty()  
      int size()
      Returns number of bindings contained
      java.lang.String toString()  
      TypeBindings withoutVariable​(java.lang.String name)
      Create a new instance with the same bindings as this object, except with the given variable removed.
      TypeBindings withUnboundVariable​(java.lang.String name)
      Method for creating an instance that has same bindings as this object, plus an indicator for additional type variable that may be unbound within this context; this is needed to resolve recursive self-references.

      • withUnboundVariable

        public TypeBindings withUnboundVariable​(java.lang.String name)
        Method for creating an instance that has same bindings as this object, plus an indicator for additional type variable that may be unbound within this context; this is needed to resolve recursive self-references.

      • withoutVariable

        public TypeBindings withoutVariable​(java.lang.String name)
        Create a new instance with the same bindings as this object, except with the given variable removed. This is used to create generic types that are "partially raw", i.e. only have some variables bound.
