      • getMIMEType

        public static java.lang.String getMIMEType​(java.lang.String pFileExt)
        Returns the default MIME type for the given file extension.
        Parameters:
        pFileExt - the file extension
        Returns:
        a String containing the MIME type, or null if there are no known MIME types for the given file extension.

      • getMIMETypes

        public static java.util.List<java.lang.String> getMIMETypes​(java.lang.String pFileExt)
        Returns all MIME types for the given file extension.
        Parameters:
        pFileExt - the file extension
        Returns:
        a List of Strings containing the MIME types, or an empty list, if there are no known MIME types for the given file extension.

      • getMIMETypeMappings

        public static java.util.Map<java.lang.String,​java.util.List<java.lang.String>> getMIMETypeMappings()
        Returns an unmodifiabale Map view of the extension to MIME mapping, to use as the default mapping in client applications.
        Returns:
        an unmodifiabale Map view of the extension to MIME mapping.

      • getExtension

        public static java.lang.String getExtension​(java.lang.String pMIME)
        Returns the default file extension for the given MIME type. Specifying a wildcard type will return null.
        Parameters:
        pMIME - the MIME type
        Returns:
        a String containing the file extension, or null if there are no known file extensions for the given MIME type.

      • getExtensions

        public static java.util.List<java.lang.String> getExtensions​(java.lang.String pMIME)
        Returns all file extension for the given MIME type. The default extension will be the first in the list. Note that no specific order is given for wildcard types (image/*, */* etc).
        Parameters:
        pMIME - the MIME type
        Returns:
        a List of Strings containing the MIME types, or an empty list, if there are no known file extensions for the given MIME type.
