core methods needed, and also exposes
more complete API to generator implementation classes.Modifier and Type | Field and Description |

_currentName
Name of the field of which value is to be written; only
used for OBJECT contexts

_dups |
protected boolean |
_gotName
Marker used to indicate that we just wrote a name, and
now expect a value to write
|

Parent context for this context; null for root context.

Modifier and Type | Method and Description |
---|---|
protected void |
appendDesc(StringBuilder sb) |
JsonWriteContext |
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). |
JsonWriteContext |
createChildArrayContext() |
JsonWriteContext |
createChildObjectContext() |
static JsonWriteContext |
createRootContext()
Deprecated.
Since 2.3; use method that takes argument
|
static JsonWriteContext |
createRootContext(DupDetector dd) |
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() |
JsonWriteContext |
getParent()
Accessor for finding parent context of this context; will
return null for root context.
|
protected JsonWriteContext |
reset(int type) |
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) ). |
String |
toString()
Overridden to provide developer writeable "JsonPath" representation
of the context.
|
JsonWriteContext |

int |
writeFieldName(String name)
Method that writer is to call before it writes a field name.

JsonStreamContext
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.
