public class ParsedReaderSwap
extends ObjectSwap<Reader,Object>

Transforms the contents of a Reader into an Object.

Description

The Reader must contain JSON, Juneau-generated XML (output from XmlSerializer), or Juneau-generated HTML (output from JsonSerializer) in order to be parsed correctly.

Useful for serializing models that contain Readers created by RestCall instances.

This is a one-way transform, since Readers cannot be reconstituted.

Behavior-specific subclasses

The following direct subclasses are provided for convenience:

• ParsedReaderSwap.Json - Parses JSON text.
• ParsedReaderSwap.Xml - Parses XML text.
• ParsedReaderSwap.Html - Parses HTML text.
• ParsedReaderSwap.PlainText - Parses plain text.
