Enum FileSystem

  • All Implemented Interfaces:
    Serializable, Comparable<FileSystem>
    public enum FileSystem
extends Enum<FileSystem>
    Abstracts an OS' file system details, currently supporting the single use case of converting a file name String to a legal file name with toLegalFileName(String, char).

    The starting point of any operation is getCurrent() which gets you the enum for the file system that matches the OS hosting the running JVM.

    Since:
    2.7

    • Enum Constant Detail

      • GENERIC

        public static final FileSystem GENERIC
        Generic file system.

      • LINUX

        public static final FileSystem LINUX
        Linux file system.

      • MAC_OSX

        public static final FileSystem MAC_OSX
        MacOS file system.

      • WINDOWS

        public static final FileSystem WINDOWS
        Windows file system.

    • Method Detail

      • values

        public static FileSystem[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (FileSystem c : FileSystem.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static FileSystem valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null

      • getCurrent

        public static FileSystem getCurrent()
        Gets the current file system.
        Returns:
        the current file system

      • getIllegalFileNameChars

        public char[] getIllegalFileNameChars()
        Gets a cloned copy of the illegal characters for this file system.
        Returns:
        the illegal characters for this file system.

      • getMaxFileNameLength

        public int getMaxFileNameLength()
        Gets the maximum length for file names. The file name does not include folders.
        Returns:
        the maximum length for file names.

      • getMaxPathLength

        public int getMaxPathLength()
        Gets the maximum length of the path to a file. This can include folders.
        Returns:
        the maximum length of the path to a file.

      • getReservedFileNames

        public String[] getReservedFileNames()
        Gets a cloned copy of the reserved file names.
        Returns:
        the reserved file names.

      • isCasePreserving

        public boolean isCasePreserving()
        Whether this file system preserves case.
        Returns:
        Whether this file system preserves case.

      • isCaseSensitive

        public boolean isCaseSensitive()
        Whether this file system is case-sensitive.
        Returns:
        Whether this file system is case-sensitive.

      • isLegalFileName

        public boolean isLegalFileName​(CharSequence candidate)
        Checks if a candidate file name (without a path) such as "filename.ext" or "filename" is a potentially legal file name. If the file name length exceeds getMaxFileNameLength(), or if it contains an illegal character then the check fails.
        Parameters:
        candidate - a candidate file name (without a path) like "filename.ext" or "filename"
        Returns:
        true if the candidate name is legal

      • isReservedFileName

        public boolean isReservedFileName​(CharSequence candidate)
        Returns whether the given string is a reserved file name.
        Parameters:
        candidate - the string to test
        Returns:
        true if the given string is a reserved file name.

      • supportsDriveLetter

        public boolean supportsDriveLetter()
        Tests whether this file system support driver letters.

        Windows supports driver letters as do other operating systems. Whether these other OS's still support Java like OS/2, is a different matter.

        Returns:
        whether this file system support driver letters.
        Since:
        2.9.0
        See Also:
        Operating systems that use drive letter assignment

      • toLegalFileName

        public String toLegalFileName​(String candidate,
                              char replacement)
        Converts a candidate file name (without a path) like "filename.ext" or "filename" to a legal file name. Illegal characters in the candidate name are replaced by the replacement character. If the file name length exceeds getMaxFileNameLength(), then the name is truncated to getMaxFileNameLength().
        Parameters:
        candidate - a candidate file name (without a path) like "filename.ext" or "filename"
        replacement - Illegal characters in the candidate name are replaced by this character
        Returns:
        a String without illegal characters
