Real value - POJO, Containerable, Objectable or Referencable.

Throws:

IOException

SchemaException

                                  SchemaException

Description copied from interface: PrismParser

Parses the input into RootXNode. This is a bit unusual approach, skipping the unmarshalling phase altogether. But it is useful at some places.

Returns:

RootXNode corresponding to the input.

Throws:

IOException

SchemaException

parseObjects

@NotNull
public @NotNull List<PrismObject<? extends Objectable>> parseObjects()
                                                              throws SchemaException,

Description copied from interface: PrismParser

Parses the input as a collection of prism objects. For XML the input must be formatted as a collection of objects (TODO change this). For other languages the input may contain one or more objects.

Returns:

A list of objects.

Throws:

SchemaException

IOException

parseObjectsIteratively

public void parseObjectsIteratively(@NotNull
                                    @NotNull PrismParser.ObjectHandler handler)

                                    IOException

Description copied from interface: PrismParser

Currently implemented for JSON/YAML only. For XML, use old Validator code.

Throws:

SchemaException

IOException

parseItemOrRealValue

public Object parseItemOrRealValue()
                            throws IOException,
                                   SchemaException

Description copied from interface: PrismParser

Parses either an item, or a real value. It depends on the type declaration or item name in the source data. 1) If explicit type is present, it is taken into account. If it corresponds to a prism item, the input is parsed as a prism item. Otherwise, it is parsed as a real value (containerable or simple POJO), if possible. 2) If there is no type, the item name is consulted. If it corresponds to a prism item, the input is parsed as a prism item. Otherwise, an exception is thrown. Pre-set parameters (itemDefinition, typeName, itemName) must NOT be present. Use with utmost care. If at all possible, avoid it.

Returns:

either prism item (Item) or a real value (Object)

Throws:

IOException

SchemaException
