- gw.internal.gosu.properties.PropertyNode
-
- All Implemented Interfaces:
IGosuObject
public class PropertyNode extends Object implements IGosuObject
A node in a tree representation of an underlyingPropertySet
. 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.

Method Detail
-
buildTree
public static PropertyNode buildTree(PropertySet propertySet)
-
getFullName
public 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 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 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 interfaceIGosuObject
- Returns:
- intrinsic type
-
hasValue
public boolean hasValue()
Does this property node have a value in the underlyingPropertySet
- Returns:
- true if the node has an underlying value, false otherwise
-
getValue
public String getValue()
Return the value for this property as given by the underlyingPropertySet
- 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?- Returns:
- true if this is the root, false otherwise
-
getChildren
public List<PropertyNode> getChildren()
The direct children of this property node- Returns:
- a non null, though possibly empty, list of children
-
getChildValue
public String getChildValue(String name)
Return the value for the named child property; this is just like doing lookup on the underlyingPropertySet
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:
name
- non null name of child property- Returns:
- the child property value, or null if there is no such child property
-
toString
public String toString()
If this node has a property value, returns the value of that property. Otherwise returns a string describing the property name.- Specified by:
toString
in interfaceIGosuObject
- Overrides:
toString
in classObject
-
getPath
public String getPath()
-
getParent
public PropertyNode getParent()
