All Implemented Interfaces:

IGosuObject
```
public class PropertyNode
extends java.lang.Object
implements IGosuObject
```
A node in a tree representation of an underlying PropertySet. Any compound names, such as a.b.c and a.b.d, in the keys of the property set are split into a tree representation. In the a.b.c/a.b.d example there would be a property node for a, with a child node b with two further leaf children c and d.

  - buildTree
```
public static PropertyNode buildTree(PropertySet propertySet)
```
  - getFullName
```
public java.lang.String getFullName()
```
    The full property name, for example a.b
    
    Returns:
    
    a non null name, which must be one or more valid Gosu identifiers separated by periods
  - getRelativeName
```
public java.lang.String getRelativeName()
```
    The last part of the property name, for example b if the full name is a.b
    
    Returns:
    
    a non null name, which must be a valid Gosu identifier
  - getTypeName
```
public java.lang.String getTypeName()
```
    Return the name that should be used for the type based on this property node
    
    Returns:
    
    a non null type name
  - getIntrinsicType
```
public IType getIntrinsicType()
```
    Return the intrinsic type based on this property node
    
    Specified by:
    
    getIntrinsicType in interface IGosuObject
    
    Returns:
    
    intrinsic type
  - hasValue
```
public boolean hasValue()
```
    Does this property node have a value in the underlying PropertySet
    
    Returns:
    
    true if the node has an underlying value, false otherwise
  - getValue
```
public java.lang.String getValue()
```
    Return the value for this property as given by the underlying PropertySet
    
    Returns:
    
    the property value, or null if it doesn't have one
  - isLeaf
```
public boolean isLeaf()
```
    Is this a leaf node - that is, does it have no children?
    
    Returns:
    
    true if this node has no children, false otherwise
  - isRoot
```
public boolean isRoot()
```
    Is this the root of a property node tree?

```
public java.util.List<PropertyNode> getChildren()
```
    The direct children of this property node
    
    Returns:
    
    a non null, though possibly empty, list of children
  - getChildValue
```
public java.lang.String getChildValue(java.lang.String name)
```
    Return the value for the named child property; this is just like doing lookup on the underlying PropertySet except that the name is prefixed with the full name of this property. For example if this property is a then getting the child value b.c will return the value of a.b.c in the original property set
    
    Parameters:
