Class for matching regular expressions.
TF_API bool Match(const std::string &query, std::string *errorMsg=NULL) const
Returns true if query matches the matcher's pattern.
TF_API TfPatternMatcher()
Construct an empty (invalid) TfPatternMatcher.
TF_API void SetIsCaseSensitive(bool sensitive)
Set this matcher to match case-sensitively or not.
TF_API bool IsValid() const
Returns true if the matcher has a valid pattern.
bool IsCaseSensitive() const
Returns true if the matcher has been set to be case sensitive, false otherwise.
bool IsGlobPattern() const
Returns true if the matcher has been set to treat patterns as glob patterns, false otherwise.
TF_API const std::string & GetPattern() const
Returns the matcher's pattern string.
TF_API std::string GetInvalidReason() const
If IsValid() returns true, this will return the reason why (if any).
TF_API void SetPattern(const std::string &pattern)
Set the pattern that this matcher will use to match against.
TF_API void SetIsGlobPattern(bool isGlob)
Set this matcher to treat its pattern as a glob pattern.
