Construct a set of rules by which local files may not be named on the file-system.

Parameters:

transformationMatrix - how to make specific characters safe, may be null

unsafePrefixes - which name prefixes are proscribed, may be null

unsafeSuffixes - which name suffixes are proscribed, may be null

unsafeNames - which names are proscribed, may be null

safeCharacters - safe characters that may be used in making file names safe, may not be null

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
