B4RLibraryB4R [MODULE]

GlobalStore - Global objects storage [module]

As explained in the tutorial about memory management in B4R: https://www.b4x.com/android/forum/threads/65672/#content it is not trivial to assign the value of a local, non-numeric, variable to a global variable.The reason behind this limitation is that the memory is statically allocated during compilation. It is therefore only possible to set fixed-size values (such as numbers).The attached module uses B4RSerializator to convert the objects to bytes and then copies them to a global buffer.Using it is simple. You need to call Store to put an object and you need to get objects from the GlobalStore.Objects array.By default there are 5 slots that you can use. This can be changed by modifying the code.
