org.mule.metadata.persistence.JsonMetadataTypeWriter

All Implemented Interfaces:

TypeWriter

public class JsonMetadataTypeWriter
extends MetadataTypeVisitor
implements TypeWriter

TypeWriter that serializes MetadataType objects into a readable and processable JSON file, that can be deserialized again into a MetadataType using JsonMetadataTypeLoader. This class is not Thread-safe.

Since:

1.0

Constructor Detail

JsonMetadataTypeWriter

public JsonMetadataTypeWriter()

Creates a new instance which serializes all types explicitly without handling references

JsonMetadataTypeWriter

public JsonMetadataTypeWriter(ObjectTypeReferenceHandler referenceHandler)

Creates a new instance which handles type references through the given referenceHandler

Parameters:

referenceHandler - an ObjectTypeReferenceHandler

Method Detail

toString

public String toString(MetadataType structure)

Given a MetadataType, serializes it into JSON format, the result of the serialization will be the output of the operation as a String

Specified by:

toString in interface TypeWriter

Parameters:

structure - MetadataType to serialize.

Throws:

MetadataSerializingException

write

public void write(MetadataType metadataType,
                  com.google.gson.stream.JsonWriter jsonWriter)
           throws IOException

Given a MetadataType, serializes it into a JSON format, the result of the serialization will be written by the .

Parameters:

metadataType - MetadataType to serialize.

jsonWriter - JsonWriter which will be used to write the serialized MetadataType

Throws:

IOException

setPrettyPrint

public JsonMetadataTypeWriter setPrettyPrint(boolean prettyPrint)

Changes the value of PrettyPrint property of the JsonMetadataTypeWriter. If it is enabled, when toString(MetadataType) is executed the output String will be printed in a human readable format, otherwise, by default, the JSON will be printed in a compact and more performable format.

Parameters:

prettyPrint - boolean value indicating if the writer should pretty print the JSON

Returns:

the configured JsonMetadataTypeWriter instance
