public Class TokenBufferReadContext

extends TokenStreamContext
Class Inheritance
Imports
tools.jackson.core.*, tools.jackson.core.io.ContentReference, tools.jackson.core.json.JsonReadContext
Implementation of TokenStreamContext 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 Summary

Modifier and TypeMethod and Description
public void
assignCurrentValue(Object v)

Overrides tools.jackson.core.TokenStreamContext.assignCurrentValue.

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

public TokenBufferReadContext
createChildArrayContext()

public TokenBufferReadContext
createChildObjectContext()

public static TokenBufferReadContext
createRootContext(TokenStreamContext origContext)

public String
currentName()

Implements abstract tools.jackson.core.TokenStreamContext.currentName.

Method for accessing name associated with the current location.

public Object
currentValue()

Overrides tools.jackson.core.TokenStreamContext.currentValue.

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 TokenStreamContext
getParent()

Implements abstract tools.jackson.core.TokenStreamContext.getParent.

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

public boolean
hasCurrentName()

Overrides tools.jackson.core.TokenStreamContext.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 String currentName()

Implements abstract tools.jackson.core.TokenStreamContext.currentName.

Doc from tools.jackson.core.TokenStreamContext.currentName.

Method for accessing name associated with the current location. Non-null for PROPERTY_NAME and value events that directly follow Property names; null for root level and array values.

public Object currentValue()

Overrides tools.jackson.core.TokenStreamContext.currentValue.

Doc from tools.jackson.core.TokenStreamContext.currentValue.

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.
