public class ArrayInit_c

An ArrayInit is an immutable representation of an array initializer, such as { 3, 1, { 4, 1, 5 } }. Note that the elements of these array may be expressions of any type (e.g., Call).

ArrayInit_c

public ArrayInit_c(Position pos,
           java.util.List<Expr> elements)

ArrayInit_c

public ArrayInit_c(Position pos,
           java.util.List<Expr> elements,
           Ext ext)

Method Detail

elements

public java.util.List<Expr> elements()

Description copied from interface: ArrayInit

Get the initializer elements.

Specified by:

elements in interface ArrayInit

Returns:

A list of Expr.

elements

public ArrayInit elements(java.util.List<Expr> elements)

Description copied from interface: ArrayInit

Set the initializer elements.

Specified by:

elements in interface ArrayInit

Parameters:

elements - A list of Expr.

elements

protected <N extends ArrayInit_c> N elements(N n,
                                 java.util.List<Expr> elements)

reconstruct

protected <N extends ArrayInit_c> N reconstruct(N n,
                                    java.util.List<Expr> elements)

Reconstruct the initializer.

visitChildren

public Node visitChildren(NodeVisitor v)

Description copied from interface: NodeOps

Visit the children of the node.

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.

typeCheck

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:

typeCheck in class Node_c

Parameters:

tc - The type checking visitor.

Throws:

SemanticException

arrayOf

protected Type arrayOf(TypeSystem ts,
           Type baseType)

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.

typeCheckElements

public void typeCheckElements(TypeChecker tc,
                     Type lhsType)
                       throws SemanticException

Description copied from interface: ArrayInit

Type check the individual elements of the array initializer against the left-hand-side type. Each element is checked to see if it can be assigned to a variable of type lhsType.

Specified by:

typeCheckElements in interface ArrayInit

Parameters:

tc - The type checking visitor.

lhsType - Type to compare against.

Throws:

SemanticException - if there is a type error.

toString

public java.lang.String toString()

Overrides:

toString in class Node_c

prettyPrint

public void prettyPrint(CodeWriter w,
               PrettyPrinter tr)

Description copied from class: Node_c

Pretty-print the AST using the given CodeWriter.

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.

firstChild

public Term firstChild()

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

acceptCFG

public <T> java.util.List<T> acceptCFG(CFGBuilder<?> v,
                              java.util.List<T> succs)

Description copied from interface: TermOps

Visit this term in evaluation order, calling v.edge() for each successor in succs, if data flows on that edge.

Specified by:

acceptCFG in interface TermOps

Specified by:

acceptCFG in class Term_c

copy

public Node copy(NodeFactory nf)

Description copied from interface: NodeOps

Produce a copy of this node using the given NodeFactory.

Specified by:

copy in interface NodeOps

Overrides:

copy in class Node_c
