#define HFST_CATCH

(

E

)

Value:

catch (const E &e)                                                  \
    {                                                                   \
    std::cerr << e.file << ", line " << e.line << ": " <<       \
        e() << std::endl;                       \
    }

Macro to catch exceptions thrown with HFST_THROW.

#define HFST_EXCEPTION_CHILD_DECLARATION

(

CHILD

)

Value:

struct CHILD : public HfstException \
    { CHILD(const std::string &name,const std::string &file,size_t line); }

Declare a subclass of HfstException of type CHILD.

#define HFST_EXCEPTION_CHILD_DEFINITION

(

CHILD

)

Value:

CHILD::CHILD \
      (const std::string &name,const std::string &file,size_t line):\
      HfstException(name,file,line)\
      {}

Define a subclass of HfstException of type CHILD.

#define HFST_THROW

(

E

)

Value:

do {                              \
    hfst_set_exception(std::string(#E));                \
    throw E(#E,__FILE__,__LINE__);                    } \
  while(false)

Macro to throw an exception of type E. Use THROW instead of regular throw with subclasses of HfstException.

#define HFST_THROW_MESSAGE	(		E,
			M
	)

Value:

do {            \
    hfst_set_exception(std::string(#E));        \
    throw E(std::string(#E)+": "+std::string(M) \
            ,__FILE__,__LINE__); }              \
  while(false)

Macro to throw an exception of type E with message M. Use THROW instead of regular throw with subclasses of HfstException.
