U_CAPI UMutableCPTrie * umutablecptrie_open(uint32_t initialValue, uint32_t errorValue, UErrorCode *pErrorCode)
Creates a mutable trie that initially maps each Unicode code point to the same value.
U_CAPI void umutablecptrie_close(UMutableCPTrie *trie)
Closes a mutable trie and releases associated memory.
U_CAPI uint32_t umutablecptrie_get(const UMutableCPTrie *trie, UChar32 c)
Returns the value for a code point as stored in the trie.
U_CAPI void umutablecptrie_set(UMutableCPTrie *trie, UChar32 c, uint32_t value, UErrorCode *pErrorCode)
Sets a value for a code point.
U_CAPI UChar32 umutablecptrie_getRange(const UMutableCPTrie *trie, UChar32 start, UCPMapRangeOption option, uint32_t surrogateValue, UCPMapValueFilter *filter, const void *context, uint32_t *pValue)
Returns the last code point such that all those from start to there have the same value.
U_CAPI UCPTrie * umutablecptrie_buildImmutable(UMutableCPTrie *trie, UCPTrieType type, UCPTrieValueWidth valueWidth, UErrorCode *pErrorCode)
Compacts the data and builds an immutable UCPTrie according to the parameters.
U_CAPI void umutablecptrie_setRange(UMutableCPTrie *trie, UChar32 start, UChar32 end, uint32_t value, UErrorCode *pErrorCode)
Sets a value for each code point [start..end].
U_CAPI UMutableCPTrie * umutablecptrie_fromUCPTrie(const UCPTrie *trie, UErrorCode *pErrorCode)
Creates a mutable trie with the same contents as the immutable one.
U_CAPI UMutableCPTrie * umutablecptrie_fromUCPMap(const UCPMap *map, UErrorCode *pErrorCode)

struct UMutableCPTrie UMutableCPTrie
Mutable Unicode code point trie.
U_CAPI UMutableCPTrie * umutablecptrie_clone(const UMutableCPTrie *other, UErrorCode *pErrorCode)
Clones a mutable trie.
C API: 8-bit Unicode handling macros.
