legalizeColumnName

public static String legalizeColumnName(String name, Function<String,String> customReplace, Set<String> takenNames)

Attempts to return a legal name based on the passed in name. Illegal characters are simply removed. Custom replacement is possible through customReplace To avoid duplicated names, anything in the set takenNames will not be returned. Theses duplicates are resolved by adding sequential digits at the end of the variable name. Column names A variable's name can be any legal identifier - an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign "$", or the underscore character "_". Subsequent characters may be letters, digits, dollar signs, or underscore characters.

Parameters:

name - , customReplace, takenNames can not be null

Returns:
