Functions

func ContainsQuestions

func ContainsQuestions(str string) bool

ContainsQuestions searches string for special characters ? @param string String to be searched @return true if string contains wildcard, false otherwise

func ContainsWildcards

func ContainsWildcards(str string) bool

ContainsWildcards searches string for special characters * and ? @param string String to be searched @return true if string contains wildcard, false otherwise

func CountEscapeCharacters

func CountEscapeCharacters(str string) (result int)

CountEscapeCharacters counts the number of escape characters in the string beginning and ending at the given indices @param str string to search @param start beginning index @param end ending index @return number of escape characters in string

func GetUnescapedColonIndex

func GetUnescapedColonIndex(str string) (idx int)

GetUnescapedColonIndex searches a string for the first unescaped colon and returns the index of that colon @param str string to search @return index of first unescaped colon, or 0 if not found

func IndexOf

func IndexOf(str1, str2 string, off int) int

IndexOf searches a string for the first occurrence of another string, starting at a given offset. @param str1 String to search. @param str2 String to search for. @param off Integer offset or -1 if not found.

func IsAlpha

func IsAlpha(r rune) bool

IsAlpha returns true if the rune contains only 'a'..'z' and 'A'..'Z'.

func IsAlphanum

func IsAlphanum(s string) bool

IsAlphanum returns true if the string contains only alphanumeric characters or the underscore character, false otherwise. @param c the string in question @return true if c is alphanumeric or underscore, false if not

func IsValidAttribute

func IsValidAttribute(attribute string) (valid bool)

IsValidAttribute validates an attribute name

func LengthWithEscapeCharacters

func LengthWithEscapeCharacters(str string) (result int)

LengthWithEscapeCharacters counts the number of characters with escape characters

func ValidateFS

func ValidateFS(in string) error

ValidateFS is not part of the reference implementation pseudo code found in the CPE 2.3 specification. It enforces three rules found in the specification:

Formatted string must start with the characters "cpe:2.3:"
A formatted string must contain 11 components
A formatted string must not contain empty components

If any rule is violated, a ParseException is thrown.

func ValidateStringValue

func ValidateStringValue(svalue string) (err error)

ValidateStringValue validates an string value

func ValidateURI

func ValidateURI(in string) error

ValidateURI is not part of the reference implementation pseudo code found in the CPE 2.3 specification. It enforces two rules in the specification:

URI must start with the characters "cpe:/"
A URI may not contain more than 7 components

If either rule is violated, a ParseErr is thrown.

@see <a href="http://cpe.mitre.org">cpe.mitre.org</a> for details.

func NewWellFormedName

func NewWellFormedName() WellFormedName

NewWellFormedName constructs a new WellFormedName object, with all components set to the default value "ANY".

func (WellFormedName) Get
