Constructors
Initializes a new instance of the ChildParseContext class that delegates to the provided context and adds the currentObject to the objectStack.
Parameters
A map of options to pass to the method.
- parentContext - IParseContext
- The parent context.
- currentObject - any
- The current object to add to the objectStack and return in getCurrent.
Initializes a new instance of the ChildParseContext class that delegates to the provided context.
Parameters
A map of options to pass to the method.
- parentContext - IParseContext
- The parent context.
Properties
Gets the currently active graph object.
Implements
Gets the current nesting of created graphs and graph elements.
Remarks
Implements
Gets the parent context.
Property Value
Gets an implementation of IParseEvents that allows to subscribe to various events in the parse process.

Methods
Deserialize the object representation in targetNode.
Remarks
context as the first argument and should be used in virtually all cases.Type Parameters

- targetType - Constructor<T>
- The desired target type.
- targetNode - Node
- The XML node that should be deserialized.
Returns
- ↪T?
- an instance of
Tornull.
Throws
- Exception({ name: 'DeserializationNotSupportedError' })

Deserialize the object representation in targetNode
Remarks
context instance is used.Type Parameters
- T
Parameters
A map of options to pass to the method.
- targetType - Constructor<T>
- The expected return type.
- context - IParseContext
- The current parse context.
- targetNode - Node
- The XML node that should be deserialized.
Returns
- ↪T?
- The deserialized object from
targetNodeor an DeserializationNotSupportedError iftargetNodecould not be deserialized.

Implements
Returns the most current (the last element) within the container hierarchy as it is returned by objectStack or default(T) if the most current element is not of the desired target type.
Type Parameters
- T
Parameters
A map of options to pass to the method.
- itemType - Constructor<T>
- The desired target type.
Returns
- ↪T?
- The most current element within the container hierarchy or
default(T).
Implements
Get a property value that specifies information about how to handle specific cases.
Parameters
A map of options to pass to the method.
- key - string
- The identifier for the property
Returns
- ↪any?
- The property value, or
nullif no such property exists.
Implements
Returns an instance that implements the given type or null.
Remarks
null implementations for the types, nor does it have to return the same instance any time. Also, it depends on the type and context whether the instance returned stays up to date or needs to be re-obtained for further use.Type Parameters
- T
Parameters
A map of options to pass to the method.
- type - Constructor<T>
- the type for which an instance shall be returned
Returns
- ↪T?
- an instance that is assignable to the type or
null
Implements
Removes a previously locally set deserialization property.
Parameters
A map of options to pass to the method.
- key - string
- The key for which the local property override should be removed.
Removes a local lookup override that has been added using setLookup
Type Parameters
- T
- The type key to remove.
Parameters
A map of options to pass to the method.
- tType - Constructor<T>
- The type key to remove.
Adds another lookup result to the local lookup override.
Type Parameters
- T
- The type to use as a key for the lookup.
Parameters
A map of options to pass to the method.
- tType - Constructor<T>
- The type to use as a key for the lookup.
- value - T
- The value to provide for queries to
T.
