edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.util.TokenBufferReadContext

public class TokenBufferReadContext
extends JsonStreamContext

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.

Method Details

getCurrentValue

public Object getCurrentValue()

Description copied from class: JsonStreamContext

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.

Overrides:

getCurrentValue in class JsonStreamContext

Returns:

Currently active value, if one has been assigned.

setCurrentValue

public void setCurrentValue(Object v)

Description copied from class: JsonStreamContext

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)).

Overrides:

setCurrentValue in class JsonStreamContext

Parameters:

v - Current value to assign to this context

createRootContext

public static TokenBufferReadContext createRootContext(JsonStreamContext origContext)

createChildArrayContext

public TokenBufferReadContext createChildArrayContext()

createChildObjectContext

public TokenBufferReadContext createChildObjectContext()

parentOrCopy

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.

getCurrentName

public String getCurrentName()

Description copied from class: JsonStreamContext

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.

Specified by:

getCurrentName in class JsonStreamContext

Returns:

Current field name within context, if any; null if none

hasCurrentName

public boolean hasCurrentName()

Overrides:

hasCurrentName in class JsonStreamContext

Returns:

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

getParent

public JsonStreamContext getParent()

Description copied from class: JsonStreamContext

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

Specified by:

getParent in class JsonStreamContext

Returns:

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

setCurrentName

public void setCurrentName(String name)
                    throws JsonProcessingException

Throws:

JsonProcessingException

updateForValue

public void updateForValue()

2.10.1
