Method Detail

reset
```
public JsonOutput reset()
```
Resets this output for re-use.

use
```
public JsonOutput use(Schema<?> schema)
```
Before serializing a message/object tied to a schema, this should be called. This also resets the internal state of this output.

isNumeric
```
public boolean isNumeric()
```
Returns whether the incoming messages' field names are numeric.

getLastNumber
```
public int getLastNumber()
```
Gets the last field number written.

isLastRepeated
```
public boolean isLastRepeated()
```
Returns true if the last written field was a repeated field.

updateLast
```
public void updateLast(Schema<?> schema,
                       Schema<?> lastSchema)
```
Description copied from interface: StatefulOutput

Updates the schema if lastSchema was indeed the last schema used.
