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.
