Parameters:

value - to check

Returns:

true for validity as a C++ name. false if not.

isCppKeyword

public static boolean isCppKeyword(java.lang.String token)

isSbeJavaName

public static boolean isSbeJavaName(java.lang.String value)

Check string for validity of usage as a Java identifier. Avoiding keywords.

http://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.9

Parameters:

value - to check

Returns:

true for validity as a Java name. false if not.

isJavaKeyword

public static boolean isJavaKeyword(java.lang.String token)

Is this token a Java keyword?

Parameters:

token - to be tested.

Returns:

true if a Java keyword otherwise false.

isSbeGolangName

public static boolean isSbeGolangName(java.lang.String value)

"Check" value for validity of usage as a golang identifier. From: https://golang.org/ref/spec#Identifiers

identifier = letter { letter | unicode_digit } letter = unicode_letter | "_" .

unicode_letter and unicode_digit are defined in section 4.5 of the the unicode standard at http://www.unicode.org/versions/Unicode8.0.0/ and the Java Character and Digit functions are unicode friendly

Parameters:

value - to check

Returns:

true for validity as a golang name. false if not.

isGolangKeyword

public static boolean isGolangKeyword(java.lang.String token)

isSbeCSharpName

public static boolean isSbeCSharpName(java.lang.String value)

"Check" value for validity of usage as a csharp identifier. https://msdn.microsoft.com/en-us/library/aa664670(v=vs.71).aspx ( Which basically boils down to

first subsequent* first is { @ | letter | underscore } subsequent is { first | digit | connecing | combining | formatting }*

letter is Lu, Ll, Lt, Lm, Lo, or Nl (possibly escaped) digit is Nd (possibly escaped) connecting is Pc (possibly escaped) combining is Mn or Mc (possibly escaped) formatting is Cf (possibly escaped)

so that all becomes: { @ | _ | Lu | Ll | Lt | Lm | Lo | Nl } { @ | _ | Lu | Ll | Lt | Lm | Lo | Nl | Nd | Pc | Mn | Mc | Cf}*

Parameters:

value - to check

Returns:

true for validity as a csharp name. false if not.
