      • read

        Metadata read​(java.io.File input,
              java.util.Map<java.lang.String,​?> options)
       throws java.io.IOException,
              MetadataParseException
        Reads the metadata from the specified file.
        Parameters:
        input - The file to deserialize the metadata from, must not be null.
        options - The options to use for deserialization, may be null to use the default values.
        Returns:
        The deserialized metadata, never null.
        Throws:
        java.io.IOException - If the metadata could not be deserialized.

       throws java.io.IOException,
              MetadataParseException
        Reads the metadata from the specified character reader. The reader will be automatically closed before the method returns.
        Parameters:
        input - The reader to deserialize the metadata from, must not be null.
        options - The options to use for deserialization, may be null to use the default values.
