Constructor & Destructor Documentation

RegularExpression() [1/4]

lldb_private::RegularExpression::RegularExpression ( )

default

The default constructor that initializes the object state such that it contains no compiled regular expression.

RegularExpression() [2/4]

RegularExpression::RegularExpression ( llvm::StringRef  string, llvm::Regex::RegexFlags  flags = llvm::Regex::NoFlags  )

explicit

Constructor for a regular expression.

Compile a regular expression using the supplied regular expression text. The compiled regular expression lives in this object so that it can be readily used for regular expression matches. Execute() can be called after the regular expression is compiled.

Parameters

[in]	string	An llvm::StringRef that represents the regular expression to compile.
[in]	flags	An llvm::Regex::RegexFlags that modifies the matching behavior. The default is NoFlags.

Member Function Documentation

Execute()

bool RegularExpression::Execute	(	llvm::StringRef	string,
		llvm::SmallVectorImpl< llvm::StringRef > *	matches = nullptr
	)		const

Execute a regular expression match using the compiled regular expression that is already in this object against the given string.

If any parens are used for regular expression matches.

Parameters

[in]	string	The string to match against the compile regular expression.
[out]	matches	A pointer to a SmallVector to hold the matches.

Returns

true if string matches the compiled regular expression, false otherwise incl. the case regular exression failed to compile.
