Error messages

[wcmjunior]

Compiler must display error messages whenever a not supported syntax or operation is used in the input code.
Some known limitations on code written in User Function objects:

• Only Java primitive types up to 32 bits are allowed, since they are mapped directly to C types
  during translation;
• Variables declared outside the user function scope can be used for read and write operations;
• Variables declared outside the user function scope without final modifier will imply in sequential
  code translation for the given iterator;
• Variables declared outside the user function scope with final modifier will imply in parallelizable
  code translation for the given iterator;
• Arrays are not supported;
• Strings are not supported;
• Method calls are not supported;
• Nested user functions are not allowed;
• Operations with Bitmaps and HDR images are fully supported in Java sequential version and
  compiler generated version, whereas there is still work to be done on compiler generated
  code for FlatArray data type (although it works on Java sequential version).
