Define Documentation

#define EXISTS (  x   )     ((x) != 0)

check whether something exists (= is unequal to zero)

#define NOTEXISTS (  x   )     ((x) == 0)

check whether something does not exist (= is zero)

#define DUMPHEX (  ostr, addr, len   )

Dump in hex format (WORD16 units).

#define FOREVER   for(;;)

a loop-forever statement

#define NUMBEROF (  array   )     (sizeof(array)/sizeof(array[0]))

evaluate the number of elements in an array of any type

#define UIMA_STRINGIFY (  s   )     UIMA_IMP_STRINGIFY(s)

stringification of macro argument. macro argument will be converted into string constant. if the argument itself is a macro, it will be expanded before stringification

#define UIMA_IMP_STRINGIFY (  s   )     # s

#define UIMA_TPRINT (  f   )

#define STATIC_CAST (  type, expr   )     static_cast<type>(expr)

#define CONST_CAST (  type, expr   )     const_cast<type>(expr)

#define REINTERPRET_CAST (  type, expr   )     reinterpret_cast<type>(expr)

#define DYNAMIC_CAST (  type, expr   )     dynamic_cast<type>(expr)
