      • getFileURIsFromRegex

        public static java.util.Collection<java.lang.String> getFileURIsFromRegex​(java.lang.String... fileNameRegexList)

        Creates a collection of URIs from a given regex list. The given list can contain either absolute (local or remote) URIs or a Java regex expression for a local path. If a regex is given all the files whose name matches the regex will be added to the resulting list.

        The regular expressions supported by this function are Java regular expressions. If we want to get the URIS for all the files in a directory we need to pass /path/to/dir/.*

        Parameters:
        fileNameRegexList - list of regular expressions for fiel URIs
        Returns:
        list of file URIs matching the given regular expressions

      • getFileURIs

        public static java.util.Collection<java.lang.String> getFileURIs​(java.lang.String... fileNameList)
        Creates a collection of URIs from a given list of files.
        Parameters:
        fileNameList - the list of files
        Returns:
        a list of URIs

      • getFileURI

        public static java.lang.String getFileURI​(java.lang.String fileName)
        Creates a URI from a given file name.
        Parameters:
        fileName - the file
        Returns:
        a string representing the file URI
