Field Details

DEBUG

public static boolean DEBUG

Debug AST rewrite events.

If enabled, then ASTRewrite and ListRewrite throw an IllegalArgumentException if a rewrite operation tries to insert an AST node in a place where nodes of this type are not allowed (node type not a subtype of the structural property's type).

Disabled by default, since this hasn't been enforced from the beginning, and there are clients (e.g. in JDT UI refactorings) that rely on a bit of leeway here. E.g. the qualifier of a QualifiedName cannot be a MethodInvocation expression or a SimpleType, but that's sometimes the easiest solution for such a change, and ASTRewrite has no problems with it.

setNodePropertyMapper

public void setNodePropertyMapper(RewriteEventStore.INodePropertyMapper nodePropertyMapper)

Override the default way how to access children from a parent node.

Parameters:

nodePropertyMapper - The new INodePropertyMapper or null. to use the default.

clear

public void clear()

addEvent

public void addEvent(ASTNode parent,
 StructuralPropertyDescriptor childProperty,
 RewriteEvent event)

getEvent

public RewriteEvent getEvent(ASTNode parent,
 StructuralPropertyDescriptor property)

getNodeEvent

public NodeRewriteEvent getNodeEvent(ASTNode parent,
 StructuralPropertyDescriptor childProperty,
 boolean forceCreation)

getListEvent

public ListRewriteEvent getListEvent(ASTNode parent,
 StructuralPropertyDescriptor childProperty,
 boolean forceCreation)

getChangeRootIterator

public Iterator getChangeRootIterator()

hasChangedProperties

public boolean hasChangedProperties(ASTNode parent)

getPropertyLocation

public RewriteEventStore.PropertyLocation getPropertyLocation(Object value,
 int kind)

findEvent

public RewriteEvent findEvent(Object value,
 int kind)

Kind is either ORIGINAL, NEW, or BOTH

Returns:

Returns the event with the given value of null.

getOriginalValue

public Object getOriginalValue(ASTNode parent,
 StructuralPropertyDescriptor property)

getNewValue

public Object getNewValue(ASTNode parent,
 StructuralPropertyDescriptor property)

getChangedPropertieEvents

public List getChangedPropertieEvents(ASTNode parent)

getChangeKind

public int getChangeKind(ASTNode node)

getEventEditGroup
