Method Detail

combineFilePathRestrictions

public static FilePathRestrictions combineFilePathRestrictions(FilePathRestrictions... rules)

Combine sets of rules to form a set that satisfies them all and that include transformations away from Unicode control characters.

Parameters:

rules - at least one set of rules

Returns:

the intersection of the given rules, with full coverage for preventing control characters
