Methods
| Name | Description |
|---|---|
| BindingScopeBoundaries() | Retrieves the permitted scope boundaries to bind references from this node. |
| CopyFrom(IFrameworkItem, UnboundReferences) | Instructs the node to copy property values from the supplied node into itself. This method should only be used by the internal Biml framework. |
| Duplicate() | Creates a duplicate of the current node |
| Duplicate(Dictionary<IFrameworkItem, IFrameworkItem>) | Creates a duplicate of the current node with the scoped node mapping |
| Duplicate(IFrameworkItem) | Creates a duplicate of the current node with the specified parent item |
| Duplicate(IFrameworkItem, Dictionary<IFrameworkItem, IFrameworkItem>) | Creates a duplicate of the current node with the specified parent item and scoped node mapping |
| DuplicateHusk(IFrameworkItem) | Creates an empty object into which the values from the current node will be duplicated. This method should only be used by the internal Biml framework |
| DuplicateInto(IFrameworkItem, Dictionary<IFrameworkItem, IFrameworkItem>) | Copies the values from the current node into a husk object with the specified scoped node mapping. This method should only be used by the internal Biml framework |
| EmitXmlForAction(AstEnginePropertyAction) | Instructs the node to make changes to its underlying Biml code that correspond to the provided action. This method should only be used by the internal Biml framework. |
| EmitXmlForProperty(String, Int32) | Instructs the node to make changes to its underlying Biml code that correspond to the provided property and index. This method should only be used by the internal Biml framework. |
| GetBimlAttributeFragment(CulturedStringBuilder) | |
| GetBimlFragment(CulturedStringBuilder, Int32, Boolean) | Internal method used by the Biml engine to produce the XML code for the current object. |
| GetDefaultValue(String) | Retrieves the default value for the property with the name propertyName |
| GetDefaultValue<T>(String) | Retrieves the default value for the property with the name propertyName |
| GetJson(StringBuilder, ref Boolean, Boolean, Boolean, Boolean, Boolean, Boolean, Boolean, Boolean) | Generates a JavaScript Object Notation (JSON) representation of the current node |
| GetPotentialParentProperties() | Retrieves the reflection information for related properties of this node type. |
| GetPropertyValue(String) | Retrieves the current value for the property with the name propertyName |
| GetReflectionInfoFromXmlParsePath(String) | Retrieves the reflection information corresponding to the Xml parse path beginning at this node. |
| MergeFrom(IFrameworkItem, UnboundReferences, Boolean) | Instructs the node to merge property values from the supplied node into itself. This method should only be used by the internal Biml framework. |
| ParseAttribute(XAttribute, ParserContext) | |
| StructureEquals(Object) | Compares this node to the provided object to determine if all defined children and references are equal. |
