Method Details
-
getBaseValue
Description copied from class:NodePointer
Returns the value represented by the pointer before indexing. So, if the node represents an element of a collection, this method returns the collection itself.- Specified by:
getBaseValue
in classNodePointer
- Returns:
- Object value
-
isContainer
public boolean isContainer()This type of node is auxiliary.- Overrides:
isContainer
in classNodePointer
- Returns:
- true
-
getPropertyCount
public int getPropertyCount()Description copied from class:PropertyPointer
Count the number of properties represented.- Specified by:
getPropertyCount
in classPropertyPointer
- Returns:
- int
-
getPropertyNames
Description copied from class:PropertyPointer
Get the names of the included properties.- Specified by:
getPropertyNames
in classPropertyPointer
- Returns:
- String[]
-
getPropertyName
Returns the name of the currently selected property or "*" if none has been selected.- Specified by:
getPropertyName
in classPropertyPointer
- Returns:
- String
-
setPropertyName
Select a property by name.- Specified by:
setPropertyName
in classPropertyPointer
- Parameters:
propertyName
- to select
-
getPropertyIndex
public int getPropertyIndex()Index of the currently selected property in the list of all properties sorted alphabetically.- Overrides:
getPropertyIndex
in classPropertyPointer
- Returns:
- int
-
setPropertyIndex
public void setPropertyIndex(int index) Index a property by its index in the list of all properties sorted alphabetically.- Overrides:
setPropertyIndex
in classPropertyPointer
- Parameters:
index
- to set
-
getImmediateNode
If index == WHOLE_COLLECTION, the value of the property, otherwise the value of the index'th element of the collection represented by the property. If the property is not a collection, index should be zero and the value will be the property itself.- Overrides:
getImmediateNode
in classPropertyPointer
- Returns:
- Object
-
isActualProperty
protected boolean isActualProperty()Returns true if the bean has the currently selected property.- Specified by:
isActualProperty
in classPropertyPointer
- Returns:
- boolean
-
isIndexedProperty
protected boolean isIndexedProperty()Learn whether the property referenced is an indexed property.- Returns:
- boolean
-
setValue
If index == WHOLE_COLLECTION, change the value of the property, otherwise change the value of the index'th element of the collection represented by the property.- Specified by:
setValue

- Specified by:
setValue
in classNodePointer
- Parameters:
value
- to set
-
remove
public void remove()Description copied from class:NodePointer
Remove the node of the object graph this pointer points to.- Overrides:
remove
in classNodePointer
-
setValue
Set an indexed value.- Parameters:
index
- to changevalue
- to set
-
convert
Convert a value to the appropriate property type.- Parameters:
value
- to convertelement
- whether this should be a collection element.- Returns:
- conversion result
