Enumeration Type Documentation

enum csRegExpMatchError

Possible errors that can occur during matching.

Enumerator:

csrxNoError	No problems during matching.
csrxNoMatch	The pattern didn't match the string.
csrxBadBraces	There was an invalid \{. ..\} construct in the regular expression. A valid \{...\} construct must contain either a single number, or two numbers in increasing order separated by a comma.
csrxBadPattern	There was a syntax error in the regular expression.
csrxBadRepetition	A repetition operator such as ? or * appeared in a bad position (with no preceding subexpression to act on).
csrxErrCollate	The regular expression referred to an invalid collating element (one not defined in the current locale for string collation).
csrxErrCharType	The regular expression referred to an invalid character class name.
csrxErrEscape	The regular expression ended with \.
csrxErrSubReg	There was an invalid number in the \digit construct.
csrxErrBrackets	There were unbalanced square brackets in the regular expression.
csrxErrParentheses	An extended regular expression had unbalanced parentheses, or a basic regular expression had unbalanced \( and \).
csrxErrBraces	The regular expression had unbalanced \{ and \}.
csrxErrRange	One of the endpoints in a range expression was invalid.
csrxErrSpace	Out of memory.
csrxErrUnknown	Unknown error.

enum csRegExpMatchFlags

Flags for regular expression matching.

Enumerator:

csrxIgnoreCase	Ignore case when matching letters.
csrxNewLine	Treat a newline in string as dividing string into multiple lines, so that $ can match before the newline and ^ can match after. Also, don't permit . to match a newline, and don't permit [^...] to match a newline. Otherwise, newline acts like any other ordinary character.
csrxNotBOL	Do not regard the beginning of the specified string as the beginning of a line; more generally, don't make any assumptions about what text might precede it.
csrxNotEOL	Do not regard the end of the specified string as the end of a line; more generally, don't make any assumptions about what text might follow it.
