Returns:

A new AST if a change was made, or this.

buildTypes

public Node buildTypes(TypeBuilder tb)
                throws SemanticException

Description copied from interface: NodeOps

Collects classes, methods, and fields from the AST rooted at this node and constructs type objects for these. These type objects may be ambiguous. Inserts classes into the TypeSystem. This method is called by the leave() method of the visitor. The method should perform work that should be done after visiting the children of the node. The method may return this or a new copy of the node which will be installed as a child of the node's parent.

Specified by:

buildTypes in interface NodeOps

Overrides:

buildTypes in class Node_c

Parameters:

tb - The visitor which adds new type objects to the TypeSystem.

Throws:

SemanticException

public Node typeCheck(TypeChecker tc)
               throws SemanticException

Description copied from interface: NodeOps

Type check the AST. This method is called by the leave() method of the visitor. The method should perform work that should be done after visiting the children of the node. The method may return this or a new copy of the node which will be installed as a child of the node's parent.

Specified by:

typeCheck in interface NodeOps

Overrides:

Parameters:

tc - The type checking visitor.

Throws:

SemanticException

childExpectedType

public Type childExpectedType(Expr child,
                     AscriptionVisitor av)

Description copied from interface: NodeOps

Get the expected type of a child expression of this. The expected type is determined by the context in that the child occurs (e.g., for x = e, the expected type of e is the declared type of x. The expected type should impose the least constraints on the child's type that are allowed by the parent node.

Specified by:

childExpectedType in interface NodeOps

Overrides:

childExpectedType in class Node_c

Parameters:

child - A child expression of this node.

av - An ascription visitor.

Returns:

The expected type of child.

Overrides:

extRewrite in class Term_c

Parameters:

rw - The visitor.

Throws:

Description copied from interface: TermOps

Return the first direct subterm performed when evaluating this term. If this term has no subterms, this should return null. This method is similar to the deprecated entry(), but it should *not* recursively drill down to the innermost subterm. The direct child visited first in this term's dataflow should be returned.

Specified by:

firstChild in interface TermOps

Specified by:

firstChild in class Term_c
