Iterator (const UChar *trieUChars, int32_t maxStringLength, UErrorCode &errorCode) | |
Iterates from the root of a UChar-serialized UCharsTrie. | |
Iterator (const UCharsTrie &trie, int32_t maxStringLength, UErrorCode &errorCode) | |
Iterates from the current state of the specified UCharsTrie. | |
~Iterator () | |
Destructor. | |
Iterator & | reset () |
Resets this iterator to its initial state. | |

UCharsTrie::Iterator::Iterator | ( | const UChar * | trieUChars, |
int32_t | maxStringLength, | ||
UErrorCode & | errorCode | ||
) |
Iterates from the root of a UChar-serialized UCharsTrie.
trieUChars | The trie UChars. |
maxStringLength | If 0, the iterator returns full strings. Otherwise, the iterator returns strings with this maximum length. |
errorCode | Standard ICU error code. Its input value must pass the U_SUCCESS() test, or else the function returns immediately. Check for U_FAILURE() on output or use with function chaining. (See User Guide for details.) |
UCharsTrie::Iterator::Iterator | ( | const UCharsTrie & | trie, |
int32_t | maxStringLength, | ||
UErrorCode & | errorCode | ||
) |
Iterates from the current state of the specified UCharsTrie.
trie | The trie whose state will be copied for iteration. |
maxStringLength | If 0, the iterator returns full strings. Otherwise, the iterator returns strings with this maximum length. |
errorCode | Standard ICU error code. Its input value must pass the U_SUCCESS() test, or else the function returns immediately. Check for U_FAILURE() on output or use with function chaining. (See User Guide for details.) |

UBool UCharsTrie::Iterator::hasNext | ( | ) | const |
UBool UCharsTrie::Iterator::next | ( | UErrorCode & | errorCode | ) |
Finds the next (string, value) pair if there is one.
If the string is truncated to the maximum length and does not have a real value, then the value is set to -1. In this case, this "not a real value" is indistinguishable from a real value of -1.
errorCode | Standard ICU error code. Its input value must pass the U_SUCCESS() test, or else the function returns immediately. Check for U_FAILURE() on output or use with function chaining. (See User Guide for details.) |
Resets this iterator to its initial state.
