    • nullConstructor

      public static void nullConstructor(ClassEmitter ce)

    • processArray

      public static void processArray(GeneratorAdapter e, Type type, ProcessArrayCallback callback)
      Process an array on the stack. Assumes the top item on the stack is an array of the specified type. For each element in the array, puts the element on the stack and triggers the callback.
      参数:
      type - the type of the array (type.isArray() must be true)
      callback - the callback triggered for each element

    • processArrays

      public static void processArrays(CodeEmitter e, Type type, ProcessArrayCallback callback)
      Process two arrays on the stack in parallel. Assumes the top two items on the stack are arrays of the specified class. The arrays must be the same length. For each pair of elements in the arrays, puts the pair on the stack and triggers the callback.
      参数:
      type - the type of the arrays (type.isArray() must be true)
      callback - the callback triggered for each pair of elements

    • hashCode

      @Deprecated public static void hashCode(GeneratorAdapter e, Type type, int multiplier, Customizer customizer)
      已过时。
      use hashCode(GeneratorAdapter, Type, int, CustomizerRegistry) instead

    • hashCode

      public static void hashCode(GeneratorAdapter e, Type type, int multiplier, CustomizerRegistry registry)

    • notEquals

      public static void notEquals(CodeEmitter e, Type type, Label notEquals, CustomizerRegistry registry)
      Branches to the specified label if the top two items on the stack are not equal. The items must both be of the specified class. Equality is determined by comparing primitive values directly and by invoking the equals method for Objects. Arrays are recursively processed in the same manner.
