Method Detail

configure

public ExtendedJsonDecoder configure(InputStream in)
                              throws IOException

Reconfigures this JsonDecoder to use the InputStream provided.

If the InputStream provided is null, a NullPointerException is thrown.

Otherwise, this JsonDecoder will reset its state and then reconfigure its input.

Parameters:

in - The IntputStream to read from. Cannot be null.

Returns:

this JsonDecoder

Throws:

IOException

configure

public ExtendedJsonDecoder configure(String in)
                              throws IOException

Reconfigures this JsonDecoder to use the String provided for input.

If the String provided is null, a NullPointerException is thrown.

Otherwise, this JsonDecoder will reset its state and then reconfigure its input.

Parameters:

in - The String to read from. Cannot be null.

Returns:

this JsonDecoder
