Define Documentation

#define forMap (  keytype, valuetype, mapname, varname    )     for (MapIter<keytype,valuetype> varname (mapname); !varname.exhausted(); varname.next())

Easier iteration for Map. For example: forMap (String, String, myMap, iter) { printf("s", (CONSTR) iter.value()); } , which prints the values in the Map<String,String> to stdout. Definition at line 517 of file mmap.h.

#define forStringMap (  mapname, varname    )     for (MapIter<String,String> varname (mapname); !varname.exhausted(); varname.next())

Easier iteration for Map<String,String> alias StringMap. For example: forStringMap (myMap, iter) { printf("s", (CONSTR) iter.value()); } , which prints the values in the StringMap to stdout. Definition at line 570 of file mmap.h. Referenced by toString().

#define getOrDefault (  map, key, def    )     (map.getp(key)? *map.getp(key):def)

Tests if the key is in the map. If it is, fetches the value, otherwise uses the default. Usage: getOrDefault(myMap, "a_key", 0.1) Definition at line 443 of file mmap.h.

String joinpairs (  const StringMap &    src, char    psep = '=', char    rsep = '&' )

Constructs a string from the map, representing the key-value-pairs in format: "key1=value1&key2=value2&key3=value3". Reverse for splitPairs().

void splitpairs (  StringMap &    trg, const String &    source, char    psep = '=', char    rsep = '&' )

Constructs the map from string containing key-value-pairs in format: "key1=value1&key2=value2&key3=value3". Reverse for joinPairs().

String toString (  const StringMap &    map )

Creates a String representation of the Map in format: {"xxx"="yyy", "zzzz"="aaaa"}. Definition at line 377 of file mmap.cc. References forStringMap.
