------------------------------------
Summary: Support streaming String values using Reader
Key: JOHNZON-153
URL: https://issues.apache.org/jira/browse/JOHNZON-153
Project: Johnzon
Issue Type: Improvement
Components: Core
Environment: Currently there are 2 ways writing a String value to
JsonGenerator:
# using {{JsonGenerator#write(java.lang.String, javax.json.JsonValue)}} and
{{JsonGenerator#write(javax.json.JsonValue)}} respectively or
# using {{JsonGenerator#write(java.lang.String, java.lang.String)}} and
{{JsonGenerator#write(java.lang.String)}} respectively
where in the former case {{JsonValue}} has to be a {{JsonString}} otherwise a
ClassCastException will be thrown in
[JsonGeneratorImpl#writeJsonValue(java.lang.String,
javax.json.JsonValue)|https://github.com/apache/johnzon/blob/master/johnzon-core/src/main/java/org/apache/johnzon/core/JsonGeneratorImpl.java#L203].
It would be great to change that implementation detail so that a consumer can
implement its own implementation of {{JsonValue}} with {{ValueType#STRING}} but
working with {{Reader}} internally so that not the entire String is kept in
memory.
The use case behind that I use johonzon to write a solr-json formatted list of
update commands for solr and want to use tika to parse (potentially huge) files
into plain text sending them as individual field in my json object.
