  Constant Field Values

• _type

  protected int _type

• _index

  protected int _index

  Index of the currently processed entry. Starts with -1 to signal that no entries have been started, and gets advanced each time a new entry is started, either by encountering an expected separator, or with new values if no separators are expected (the case for root context).

Constructor Detail

• JsonStreamContext

  protected JsonStreamContext()

Method Detail

• getParent

  public abstract JsonStreamContext getParent()

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

• inArray

  public final boolean inArray()

  Method that returns true if this context is an Array context; that is, content is being read from or written to a Json Array.

• inRoot

  public final boolean inRoot()

  Method that returns true if this context is a Root context; that is, content is being read from or written to without enclosing array or object structure.

• inObject

  public final boolean inObject()

  Method that returns true if this context is an Object context; that is, content is being read from or written to a Json Object.

• getTypeDesc

  @Deprecated
  public final String getTypeDesc()

  Deprecated. Since 2.8 use typeDesc() instead
  Method for accessing simple type description of current context; either ROOT (for root-level values), OBJECT (for field names and values of JSON Objects) or ARRAY (for values of JSON Arrays)

• typeDesc

  public String typeDesc()

  Since:

  2.8

• getEntryCount

  public final int getEntryCount()

  Returns:

  Number of entries that are complete and started.

• getCurrentIndex

  public final int getCurrentIndex()

  Returns:

  Index of the currently processed entry, if any

• hasCurrentIndex

  public boolean hasCurrentIndex()

  Method that may be called to verify whether this context has valid index: will return `false` before the first entry of Object context or before first element of Array context; otherwise returns `true`.

  Since:

  2.9

• hasPathSegment

  public boolean hasPathSegment()

  Method that may be called to check if this context is either:

  • Object, with at least one entry written (partially or completely)
  • Array, with at least one entry written (partially or completely)

  and if so, return `true`; otherwise return `false`. Latter case includes Root context (always), and Object/Array contexts before any entries/elements have been read or written.

  Method is mostly used to determine whether this context should be used for constructing JsonPointer

  Since:

  2.9

• getCurrentName

  public abstract String 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.

• hasCurrentName

  public boolean hasCurrentName()

  Since:

  2.9

• getCurrentValue

  public 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.

  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:

  Currently active value, if one has been assigned.

  Since:

  2.5

• setCurrentValue

  public void setCurrentValue(Object v)

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

  Since:

  2.5

• pathAsPointer

  public JsonPointer pathAsPointer()

  Factory method for constructing a JsonPointer that points to the current location within the stream that this context is for, excluding information about "root context" (only relevant for multi-root-value cases)

  Since:

  2.9

• pathAsPointer

  public JsonPointer pathAsPointer(boolean includeRoot)

  Factory method for constructing a JsonPointer that points to the current location within the stream that this context is for, optionally including "root value index"

  Parameters:

  includeRoot - Whether root-value offset is included as the first segment or not;

  Since:

  2.9
