Converts a string by applying capitalization rules to the string.
string | input string |
capitalization | capitalization type to apply |
Definition at line 22 of file qgsstringutils.cpp.
|
static |
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 209 of file qgsstringutils.cpp.
|
static |
Returns a string with any URL (e.g., http(s)/ftp) and mailto: text converted to valid HTML <a ...> links.
string | string to insert links into |
foundLinks | if specified, will be set to true if any links were inserted into the string |
Definition at line 343 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 |
Definition at line 64 of file qgsstringutils.cpp.
|
static |
Returns the longest common substring between two strings.
This substring is the longest string that is a substring of the two input strings. For example, 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 146 of file qgsstringutils.cpp.
|
static |
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.
string | input string |
