Converti record di esempio con codifica JSON in stringhe buffer di protocollo binario.
Questa operazione traduce un tensore contenente record di esempio, codificati utilizzando la [mappatura JSON standard](https://developers.google.com/protocol-buffers/docs/proto3#json), in un tensore contenente gli stessi record codificati come protocollo binario buffer. Il tensore risultante può quindi essere alimentato a qualsiasi altra operazione di analisi dell'esempio.

Metodi pubblici
Restituisce l'handle simbolico del tensore.
Gli input per le operazioni TensorFlow sono output di un'altra operazione TensorFlow. Questo metodo viene utilizzato per ottenere un handle simbolico che rappresenta il calcolo dell'input.

Ogni stringa è un buffer di protocollo di esempio binario corrispondente al rispettivo elemento di "json_examples".
Metodo factory per creare una classe che racchiude una nuova operazione DecodeJsonExample.
