+## Throw exception when JsonBuffer is too small
+
+Here is a static decorator that will behave as the decorated `JsonBuffer`, except that it will throw an exception if the allocation fails:
+
+```c++
+#include <stdexcept>
+
+template <typename TJsonBuffer>
+struct Throwing : TJsonBuffer {
+  virtual void *alloc(size_t bytes) {
+    void *ptr = TJsonBuffer::alloc(bytes);
+    if (ptr)
+      return ptr;
+    else
+      throw std::runtime_error("allocation failed");
+  }
+};
+```
+
+To use this in your code:
+
+```c++
+Throwing<StaticJsonBuffer<200> > jsonBuffer;
+// or
+Throwing<DynamicJsonBuffer> jsonBuffer;
+```
+
+See issue [#205](https://github.com/bblanchon/ArduinoJson/issues/205).
