Package net.sourceforge.pmd.lang.java.ast

Class ASTClassType

    • Method Detail

      • isFullyQualified

        public boolean isFullyQualified()
        Returns true if the type was written with a full package qualification. For example, java.lang.Override. For nested types, only the leftmost type is considered fully qualified. Eg in p.Outer.Inner, this method will return true for the type corresponding to p.Outer, but false for the enclosing p.Outer.Inner.

      • getQualifier

        public @Nullable ASTClassType getQualifier()
        Gets the owner type of this type if it's not ambiguous. This is a type we know for sure that this type is a member of.
        Returns:
        A type, or null if this is a base type

      • getTypeArguments

        public @Nullable ASTTypeArguments getTypeArguments()
        Returns the type arguments of this segment if some are specified.

      • getPackageQualifier

        public @Nullable String getPackageQualifier()
        Return the package qualifier, if this is a fully qualified name. Note that this will only be the case if we could resolve the qualifier to a package name during disambiguation. In other words, if the auxclasspath is not complete, and the qualifier could not be disambiguated, this method will return null (and an AmbiguousName will stay in the tree).

        If a nested type is package-qualified, this method will only return a non-null result for the leftmost (=innermost) ASTClassType node. For instance in java.util.Map.Entry, the node java.util.Map has package qualifier "java.util", while the node for Entry has package qualifier null. Note that the package name of the symbol and type mirror will reflect that package name anyway, on both nodes.

      • acceptVisitor

        protected <P,​R> R acceptVisitor​(JavaVisitor<? super P,​? extends R> visitor,
                                      P data)

      • getSimpleName

        public String getSimpleName()
        Returns the simple name of this type. Use the symbol to get more information.

      • getTypeMirror

        public @NonNull JTypeMirror getTypeMirror()
        Description copied from interface: TypeNode
        Returns the compile-time type of this node. For example, for a string literal, returns the type mirror for String, for a method call, returns the return type of the call, etc.

        This method ignores conversions applied to the value of the node because of its context. For example, in 1 + "", the numeric literal will have type int, but it is converted to String by the surrounding concatenation expression. Similarly, in Collections.singletonList(1), the ASTNumericLiteral node has type int, but the type of the method formal is Integer, and boxing is applied at runtime. Possibly, an API will be added to expose this information.

        Specified by:
        getTypeMirror in interface TypeNode
        Returns:
        The type mirror. Never returns null; if the type is unresolved, returns TypeSystem.UNKNOWN.
