public Class TokenBufferReadContext

extends JsonStreamContext
Class Inheritance
Imports
com.fasterxml.jackson.core.*, com.fasterxml.jackson.core.io.ContentReference, com.fasterxml.jackson.core.json.JsonReadContext
Implementation of JsonStreamContext used by TokenBuffer to link back to the original context to try to keep location information consistent between source location and buffered content when it's re-read from the buffer.
Since
2.9

public String
getCurrentName()

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

Method for accessing name associated with the current location.

public Object
getCurrentValue()

Overrides 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.

public JsonStreamContext
getParent()

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

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

public boolean
hasCurrentName()

Overrides com.fasterxml.jackson.core.JsonStreamContext.hasCurrentName.

public TokenBufferReadContext
parentOrCopy()

Helper method we need to handle discontinuity between "real" contexts buffer creates, and ones from parent: problem being they are of different types.

public void

public void

Current value to assign to this context

Overrides com.fasterxml.jackson.core.JsonStreamContext.setCurrentValue.

Method to call to pass value to be returned via getCurrentValue; typically called indirectly through JsonParser#setCurrentValue or JsonGenerator#setCurrentValue).

public 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

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 JsonStreamContext 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:JsonStreamContext

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

public boolean hasCurrentName()

Overrides com.fasterxml.jackson.core.JsonStreamContext.hasCurrentName.

Returns:boolean

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

True if a call to getCurrentName() would return non-null name; false otherwise
