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

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.

public final AvroReadContext getParent()

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

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

Accessor for finding parent context of this context; will return null for root context.

Returns:AvroReadContext

Parent context of this context, if any; null for Root contexts

Returns:String

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

Simple developer-readable description this context layer (note: NOT constructed with parents, unlike pathAsPointer)
