Hi all.
I wanted to inform the tasks I worked on this week: Jan 30 - Feb 05 .
* Enhance the deleteSchema method (delete existing nodes when deleting the
schema constraints)
* Enhance Map, Record, Array and Bytes serialization / de-serialization
process using Base64 encoding.
* Activate tests:
testPutNested
testPutArray
testPutBytes
testPutMap
testPutMixedMaps
testGetNested
testGet3UnionField
testGetWithFields
My code is here: https://github.com/mgov88/gora/tree/GORA-663
Regards,
Gaby
