Method Detail

read

Metadata read(File input,
              Map<String,?> options)
              throws 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:

IOException - If the metadata could not be deserialized.

MetadataParseException - If the input format could not be parsed.

read

Metadata read(Reader input,
              Map<String,?> options)
              throws 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.

Returns:

The deserialized metadata, never null.

Throws:

IOException - If the metadata could not be deserialized.

MetadataParseException - If the input format could not be parsed.

read

Metadata read(InputStream input,
              Map<String,?> options)
              throws IOException,
                     MetadataParseException

Reads the metadata from the specified byte stream. The stream will be automatically closed before the method returns.

Parameters:

input - The stream 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:

IOException - If the metadata could not be deserialized.

MetadataParseException - If the input format could not be parsed.
