|
|
* appear in the first and second positions within the brackets,
|
|
* respectively. (In the former case, the behavior specified for
|
|
* '[^az]' will happen.)

|

|
|
* character represented by 'a' having a lower ASCII value than

* o pat~pat2 returns matches to the pattern 'pat' which do not also match
|
|
* the pattern 'pat2'. This may be used to perform filtering
|
|
* upon the results of one pattern to remove all matches which
|

* matches any string and '*z*' matches any string containing a
|

* 'z', '*~*z*' will match all strings except those containing
|
|
* a 'z'. Note that a pattern may not use '~' multiple times,
|
|
* so a string such as '*~*z*~*y*' is not a valid pattern.
|
|
* o (foo|bar) will match either the pattern foo or the pattern bar.
|
|
* Neither of the patterns foo or bar may use the 'pat~pat2'
|
|
* syntax described immediately above.
|
|
* o \ will escape a special character. Escaping is required for all
|
|
* special characters unless otherwise specified.
|
|
* o All other characters match case-sensitively.
|
|
*
|
|
* An aPattern not conforming to this syntax has undefined behavior.

* @throws NS_ERROR_ILLEGAL_VALUE on many but not all invalid aPattern
