com.sun.source.util.TreeScanner<R,P>

com.sun.source.util.TreePathScanner<PropertyMarker,PropertyMarker>

org.yarnandtail.andhow.compile.PropertyVariableTreeScanner

All Implemented Interfaces:

public class PropertyVariableTreeScanner
extends com.sun.source.util.TreePathScanner<PropertyMarker,PropertyMarker>

A compilation tree scanner used during compile time to scan for AndHow Property construction being assigned to a variable. The intended use is to create a new instance of this class when a variable of type org.yarnandtail.andhow.api.Property is found. The current path is passed into this classes scan() method along with a PropertyMarker. When the scan is complete, the PropertyMarker is returned, which will indicate if the Property assigned to the variable is newly constructed or just a reference to an already constructed Property.

Method Detail

visitNewClass

public PropertyMarker visitNewClass(com.sun.source.tree.NewClassTree nct,
                                    PropertyMarker p)

Specified by:

visitNewClass in interface com.sun.source.tree.TreeVisitor<PropertyMarker,PropertyMarker>

Overrides:

visitNewClass in class com.sun.source.util.TreeScanner<PropertyMarker,PropertyMarker>

visitMemberSelect

public PropertyMarker visitMemberSelect(com.sun.source.tree.MemberSelectTree mst,
                                        PropertyMarker p)

Called for the actual invocation of a specific method. This is called by visitMethodInvocation(), which is actually called at a higher level with metadata and arguments, before we get down to the level of a specific method. At that higher level, there doesn't seem to be a way to reliably pick out the name of the method being invoked.

Specified by:

visitMemberSelect in interface com.sun.source.tree.TreeVisitor<PropertyMarker,PropertyMarker>

Overrides:

visitMemberSelect in class com.sun.source.util.TreeScanner<PropertyMarker,PropertyMarker>

Parameters:

mst -

p -
