com.sun.source.util.SimpleTreeVisitor<Void,AnnotatedTypeMirror>

org.checkerframework.framework.type.treeannotator.TreeAnnotator

org.checkerframework.checker.propkey.PropertyKeyAnnotatedTypeFactory.KeyLookupTreeAnnotator

All Implemented Interfaces:

TreeVisitor<Void,AnnotatedTypeMirror>

Enclosing class:

PropertyKeyAnnotatedTypeFactory

protected class PropertyKeyAnnotatedTypeFactory.KeyLookupTreeAnnotator
extends TreeAnnotator

This TreeAnnotator checks for every String literal whether it is included in the lookup keys. If it is, the given annotation is added to the literal; otherwise, nothing happens. Subclasses of this AnnotatedTypeFactory can directly reuse this class and use a different annotation as parameter.

public Void visitBinary(BinaryTree tree,
 AnnotatedTypeMirror type)

Description copied from class: TreeAnnotator

When overriding this method, getAnnotatedType on the left and right operands should only be called when absolutely necessary. Otherwise, the checker will be very slow on heavily nested binary trees. (For example, a + b + c + d + e + f + g + h.)

If a checker's performance is still too slow, the types of binary trees could be computed in a subclass of CFTransfer. When computing the types in a transfer, look up the value in the store rather than the AnnotatedTypeFactory. Then this method should annotate binary trees with top so that the type applied in the transfer is always a subtype of the type the AnnotatedTypeFactory computes.

Specified by:

Overrides:

visitBinary in class TreeAnnotator

public Void visitCompoundAssignment(CompoundAssignmentTree tree,
 AnnotatedTypeMirror type)

Specified by:

Overrides:

visitCompoundAssignment in class SimpleTreeVisitor<Void,AnnotatedTypeMirror>
