Field Detail

enclosingInstance

public Expr enclosingInstance

The enclosing instance is the object expression before a new call ( .new T(...) ). This field may be null if there is no such expression.

Note:

If the type in question is an inner class, then the type checker will infer a [.]this expression if no expression is present and place it in this slot. (See ThisExpr for how to distinguish inferred this expressions.)

locDot

public int locDot

type

public TypeName type

args

public ExprVec args

anonDecl

public ClassDecl anonDecl

If the new expression includes a declaration of an inner class, then "anonDecl" will be non-null. In this case, the "superclass" field of "ananDecl" will be null and "superinterfaces" list of "anonDecl" will be empty. One of these fields needs to be modified during type checking depending on whether "type" is a class or an interface.

loc

public int loc

locOpenParen

public int locOpenParen

decl

public ConstructorDecl decl

childCount

public final int childCount()

Description copied from class: ASTNode

Return the number of children a node has.

Specified by:

childCount in class ASTNode

childAt

public final java.lang.Object childAt(int index)

Description copied from class: ASTNode

Return the first-but-ith child of a node.

Specified by:

childAt in class ASTNode

toString

public final java.lang.String toString()

Description copied from class: ASTNode

Return a string representation of this. Meant for debugging use only, not for presentation.

Specified by:

toString in class ASTNode

public final int getTag()

Description copied from class: ASTNode

Return the tag of a node.

Specified by:

getTag in class ASTNode

accept

public final void accept(Visitor v)

Description copied from class: ASTNode

Specified by:

accept in class ASTNode

accept

public final java.lang.Object accept(VisitorArgResult v,
                                     java.lang.Object o)

Specified by:

accept in class ASTNode

check

public void check()

Overrides:

check in class Expr
