                         Expr qualifier,
                         java.util.List arguments)

Method Detail

qualifier

public Expr qualifier()

Get the qualifier of the constructor call.

Specified by:

qualifier in interface ConstructorCall

qualifier

public ConstructorCall qualifier(Expr qualifier)

Set the qualifier of the constructor call.

Specified by:

qualifier in interface ConstructorCall

kind

public ConstructorCall.Kind kind()

Get the kind of the constructor call.

Specified by:

kind in interface ConstructorCall

kind

public ConstructorCall kind(ConstructorCall.Kind kind)

Set the kind of the constructor call.

Specified by:

kind in interface ConstructorCall

arguments

public java.util.List arguments()

Get the actual arguments of the constructor call.

Specified by:

arguments in interface ConstructorCall

Specified by:

arguments in interface ProcedureCall

Returns:

A list of Expr.

arguments

public ProcedureCall arguments(java.util.List arguments)

Set the actual arguments of the constructor call.

Specified by:

arguments in interface ConstructorCall

Specified by:

arguments in interface ProcedureCall

Parameters:

arguments - A list of Expr.

procedureInstance

public ProcedureInstance procedureInstance()

Description copied from interface: ProcedureCall

The type object of the method we are calling. This is, generally, only valid after the type-checking pass.

Specified by:

procedureInstance in interface ProcedureCall

constructorInstance

public ConstructorInstance constructorInstance()

Get the constructor we are calling.

Specified by:

constructorInstance in interface ConstructorCall

constructorInstance

public ConstructorCall constructorInstance(ConstructorInstance ci)

Set the constructor we are calling.

Specified by:

constructorInstance in interface ConstructorCall

enterScope

public Context enterScope(Context c)

An explicit constructor call is a static context. We need to record this.

Specified by:

enterScope in interface NodeOps

Overrides:

enterScope in class Node_c

Parameters:

c - the current Context

Returns:

the Context to be used for visiting this node.

reconstruct

protected ConstructorCall_c reconstruct(Expr qualifier,
                                        java.util.List arguments)

Reconstruct the constructor call.

visitChildren

public Node visitChildren(NodeVisitor v)

Visit the children of the call.

Specified by:

visitChildren in interface NodeOps

Overrides:

visitChildren in class Node_c

Parameters:

v - The visitor that will traverse/rewrite the AST.

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

typeCheck

public Node typeCheck(TypeChecker tc)
               throws SemanticException

Type check the call.

Specified by:

typeCheck in interface NodeOps

Overrides:

typeCheck in class Node_c

Parameters:

tc - The type checking visitor.

Throws:

SemanticException

childExpectedType

public Type childExpectedType(Expr child,
                              AscriptionVisitor av)

Description copied from interface: Node

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 Node

Overrides:

childExpectedType in class Node_c

Parameters:

child - A child expression of this node.

av - An ascription visitor.

Returns:

The expected type of child.

toString

public java.lang.String toString()

Overrides:

toString in class Node_c

prettyPrint

public void prettyPrint(CodeWriter w,
                        PrettyPrinter tr)

Write the call to an output file.

Specified by:

prettyPrint in interface NodeOps

Overrides:

prettyPrint in class Node_c

Parameters:

w - The code writer to which to write.

tr - The pretty printer. This is not a visitor.

entry

public Term entry()

Description copied from class: Term_c

Return the first (sub)term performed when evaluating this term.

Specified by:

entry in interface Term

Specified by:

entry in class Term_c

acceptCFG

Specified by:

throwTypes in interface NodeOps

Overrides:

throwTypes in class Node_c
