  • Field Details

    • FS_EMPTY_EXTENSIONS

      protected static final String[] FS_EMPTY_EXTENSIONS
      Empty extensions array

    • FS_STANDARD_FILE_SEPARATOR

      protected static final char FS_STANDARD_FILE_SEPARATOR
      Character used to identify all standard file separators
      See Also:

    • FS_EXTENSION_IDENTIFIER

      protected static final char FS_EXTENSION_IDENTIFIER
      Character used to identify all file extensions
      See Also:

    • FS_RESOURCE_BUFFER_SIZE_STANDARD

      protected static final int FS_RESOURCE_BUFFER_SIZE_STANDARD
      Standard size for data buffers
      See Also:

    • FS_DEFAULT_ALGORITHM

      protected static final String FS_DEFAULT_ALGORITHM
      Hash Algorithm for resourceHashImpl(InputStream, String) Function. It must be remembered that 64-bit platforms work better with 64-bit algorithms such as SHA-512 and 32-bit platforms with SHA-256, but it is possible to use both on any platform, it is only done this way for performance reasons.
