Returns the Hamming distance between two strings.
This equates to the number of characters at corresponding positions within the input strings where the characters are different. The input strings must be the same length.
string1 | first string |
string2 | second string |
caseSensitive | set to true for case sensitive comparison |
Definition at line 164 of file qgsstringutils.cpp.
|
static |
Returns the Levenshtein edit distance between two strings.
This equates to the minimum number of character edits (insertions, deletions or substitutions) required to change one string to another.
string1 | first string |
string2 | second string |
caseSensitive | set to true for case sensitive comparison |

static |
Returns the longest common substring between two strings.
This substring is the longest string that is a substring of the two input strings. Eg, the longest common substring of "ABABC" and "BABCA" is "ABC".
string1 | first string |
string2 | second string |
caseSensitive | set to true for case sensitive comparison |
Definition at line 101 of file qgsstringutils.cpp.
Returns the Soundex representation of a string.
Soundex is a phonetic matching algorithm, so strings with similar sounds should be represented by the same Soundex code.
