Class AbstractJsonTransformers

java.lang.Object
  com.legstar.coxb.transform.AbstractJsonTransformers

All Implemented Interfaces:

IHostJsonTransformers

public abstract class AbstractJsonTransformers
extends Object
implements IHostJsonTransformers

A generic class that provides transformer capabilities for a given structure.

A structure maps to an XSD and a COBOL structure. This class does not implement the transformers, it acts as a container.

Classes derived from this one will typically implement a constructor that creates the directional transformers, JSON to host and host to JSON.

Constructor Summary

AbstractJsonTransformers()
No arg constructor.

AbstractJsonTransformers(IJsonToHostTransformer jsonToHost, IHostToJsonTransformer hostToJson)
Creates a provider with its directional transformers.

IHostToJsonTransformer	getHostToJson()
IJsonToHostTransformer	getJsonToHost()
void	setHostToJson(IHostToJsonTransformer hostToJson)
void	setJsonToHost(IJsonToHostTransformer jsonToHost)
byte[]	toHost(Reader reader) Transforms JSON to host data.
byte[]	toHost(Reader reader, HostTransformStatus status) Transforms JSON source to host data.
byte[]	toHost(Reader reader, String hostCharset) Transforms JSON to host data with a specific host character set.
byte[]	toHost(Reader reader, String hostCharset, HostTransformStatus status) Transforms JSON source to host data with a specific host character set.
void	toJson(byte[] hostData, Writer writer) Transforms host data to JSON.
void	toJson(byte[] hostData, Writer writer, HostTransformStatus status) Transforms host data to JSON.
void	toJson(byte[] hostData, Writer writer, String hostCharset) Transforms host data to JSON with a specific host character set.
void	toJson(byte[] hostData, Writer writer, String hostCharset, HostTransformStatus status) Transforms host data to JSON using a specific host character set.
