  • Field Details

    • opcode

      public final int opcode
      Operation to be executed. Opcodes are defined in ScriptOpCodes.

    • data

      @Nullable public final byte[] data
      For push operations, this is the vector to be pushed on the stack. For ScriptOpCodes.OP_0, the vector is empty. Null for non-push operations.
