getCurrentName	back to summary
public final String getCurrentName() Implements abstract com.fasterxml.jackson.core.JsonStreamContext.getCurrentName. Doc from com.fasterxml.jackson.core.JsonStreamContext.getCurrentName. Method for accessing name associated with the current location. Non-null for `FIELD_NAME` and value events that directly follow field names; null for root level and array values. Returns:String Current field name within context, if any; `null` if none Annotations @Override

public final String getCurrentName()

Implements abstract com.fasterxml.jackson.core.JsonStreamContext.getCurrentName.

Doc from com.fasterxml.jackson.core.JsonStreamContext.getCurrentName.

getCurrentValue	back to summary
public Object getCurrentValue() Overrides com.fasterxml.jackson.core.JsonStreamContext.getCurrentValue. Doc from com.fasterxml.jackson.core.JsonStreamContext.getCurrentValue. Method for accessing currently active value being used by data-binding (as the source of streaming data to write, or destination of data being read), at this level in hierarchy. Note that "current value" is NOT populated (or used) by Streaming parser or generator; it is only used by higher-level data-binding functionality. The reason it is included here is that it can be stored and accessed hierarchically, and gets passed through data-binding. Returns:Object Currently active value, if one has been assigned. Annotations @Override
