| Modifier and Type | Method and Description |
|---|---|
JsonReadContext |
clearAndGetParent()
Method that can be used to both clear the accumulated references
(specifically value set with
setCurrentValue(Object))
that should not be retained, and returns parent (as would
getParent() do). |

String |
getCurrentName()
Method for accessing name associated with the current location.
|
Object |
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.
|
DupDetector |
getDupDetector() |
JsonReadContext |
getParent()
Accessor for finding parent context of this context; will
return null for root context.
|
JsonLocation |
getStartLocation(Object srcRef)
Optional method that may be used to access starting location of this context:
for example, in case of JSON `Object` context, offset at which `[` token was
read or written.
|
boolean |

setCurrentName(String name) |
void |
setCurrentValue(Object v)
Method to call to pass value to be returned via
JsonStreamContext.getCurrentValue(); typically
called indirectly through JsonParser.setCurrentValue(java.lang.Object)
or JsonGenerator.setCurrentValue(java.lang.Object)). |

public Object getCurrentValue()
JsonStreamContextNote 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.

"non-standard" read contexts.
public JsonReadContext clearAndGetParent()
setCurrentValue(Object))
that should not be retained, and returns parent (as would
getParent() do). Typically called when closing the active
context when encountering JsonToken.END_ARRAY or
JsonToken.END_OBJECT.public DupDetector getDupDetector()
