Class NameLogic

java.lang.Object

com.github.javaparser.symbolsolver.resolution.naming.NameLogic

public class NameLogic
extends Object

NameLogic contains a set of static methods to implement the abstraction of a "Name" as defined in Chapter 6 of the JLS. This code could be moved to an interface or base class in a successive version of JavaParser.

Constructor Details

NameLogic

public NameLogic()

Method Details

isSimpleName

public static boolean isSimpleName(Node node)

Is the given node a non-qualified name?

Throws:

IllegalArgumentException - if the node is not a name

isQualifiedName

public static boolean isQualifiedName(Node node)

Is the given node a qualified name?

Throws:

IllegalArgumentException - if the node is not a name

isAName

public static boolean isAName(Node node)

Does the Node represent a Name?

Note that while most specific AST classes either always represent names or never represent names there are exceptions as the FieldAccessExpr

getQualifier

private static Node getQualifier(Node node)

getRightMostName

private static Node getRightMostName(Node node)

classifyRole

public static NameRole classifyRole(Node name)

What is the Role of the given name? Does it represent a Declaration or a Reference?

This classification is purely syntactical, i.e., it does not require symbol resolution. For this reason in the future this could be moved to the core module of JavaParser.

classifyReference

public static NameCategory classifyReference(Node name,
 TypeSolver typeSolver)

reclassificationOfContextuallyAmbiguousNames

private static NameCategory reclassificationOfContextuallyAmbiguousNames(Node name,
 NameCategory ambiguousCategory,
 TypeSolver typeSolver)

JLS 6.5.2. Reclassification of Contextually Ambiguous Names

reclassificationOfContextuallyAmbiguousPackageOrTypeName

private static NameCategory reclassificationOfContextuallyAmbiguousPackageOrTypeName(Node name,
 TypeSolver typeSolver)

reclassificationOfContextuallyAmbiguousQualifiedAmbiguousName

private static NameCategory reclassificationOfContextuallyAmbiguousQualifiedAmbiguousName(Node nameNode,
 TypeSolver typeSolver)

reclassificationOfContextuallyAmbiguousSimpleAmbiguousName

private static NameCategory reclassificationOfContextuallyAmbiguousSimpleAmbiguousName(Node nameNode,
 TypeSolver typeSolver)

syntacticClassificationAccordingToContext

public static NameCategory syntacticClassificationAccordingToContext(Node name)

See JLS 6.5.1 Syntactic Classification of a Name According to Context.

Most users do not want to call directly this method but call classifyReference instead.
