Package ca.uhn.fhir.parser

Class JsonParser

java.lang.Object

ca.uhn.fhir.parser.BaseParser

ca.uhn.fhir.parser.JsonParser

All Implemented Interfaces:

IJsonLikeParser, IParser

public class JsonParser
extends BaseParser
implements IJsonLikeParser

This class is the FHIR JSON parser/encoder. Users should not interact with this class directly, but should use FhirContext.newJsonParser() to get an instance.

getEncoding

public EncodingEnum getEncoding()

Description copied from interface: IParser

Which encoding does this parser instance produce?

Specified by:

getEncoding in interface IParser

parseResource

public <T extends IBaseResource> T parseResource(Class<T> theResourceType,
 JsonLikeStructure theJsonLikeStructure)
                                          throws DataFormatException

Description copied from interface: IJsonLikeParser

Parses a resource from a JSON-like data structure

Specified by:

parseResource in interface IJsonLikeParser

Parameters:

theResourceType - The resource type to use. This can be used to explicitly specify a class which extends a built-in type (e.g. a custom type extending the default Patient class)

theJsonLikeStructure - The JSON-like structure to parse

Returns:

A parsed resource

Throws:

DataFormatException - If the resource can not be parsed because the data is not recognized or invalid for any reason

parseResource

public IBaseResource parseResource(JsonLikeStructure theJsonLikeStructure)
                            throws DataFormatException

Description copied from interface: IJsonLikeParser

Parses a resource from a JSON-like data structure

Specified by:

parseResource in interface IJsonLikeParser

Parameters:

theJsonLikeStructure - The JSON-like structure to parse

Returns:

A parsed resource. Note that the returned object will be an instance of IResource or IAnyResource depending on the specific FhirContext which created this parser.

Throws:

DataFormatException - If the resource can not be parsed because the data is not recognized or invalid for any reason

setPrettyPrint

public IParser setPrettyPrint(boolean thePrettyPrint)

Description copied from interface: IParser

Sets the "pretty print" flag, meaning that the parser will encode resources with human-readable spacing and newlines between elements instead of condensing output as much as possible.

Specified by:

setPrettyPrint in interface IParser

Parameters:

thePrettyPrint - The flag

Returns:

Returns an instance of this parser so that method calls can be chained together
