public class NewArray_c
extends Expr_c
implements NewArray

A NewArray represents a new array expression such as new File[8][] { null }. It consists of an element type (e.g., File), a list of dimension expressions (e.g., 8), 0 or more additional dimensions (e.g., 1 for []), and an array initializer. The dimensions of the array initializer must equal the number of additional "[]" dimensions.

                  java.util.List dims,
                  int addDims,
                  ArrayInit init)
Method Detail

baseType

public TypeNode baseType()
Get the base type node of the expression.

Specified by:
baseType in interface NewArray

baseType

public NewArray baseType(TypeNode baseType)
Set the base type node of the expression.

Specified by:
baseType in interface NewArray

dims

public java.util.List dims()
Get the dimension expressions of the expression.

Specified by:
dims in interface NewArray
Returns:
A list of Expr.

dims

public NewArray dims(java.util.List dims)
Set the dimension expressions of the expression.

Specified by:
dims in interface NewArray
Parameters:
dims - A list of Expr.

numDims

public int numDims()
Get the number of dimensions of the expression.

Specified by:
numDims in interface NewArray

additionalDims

public int additionalDims()
Get the number of additional dimensions of the expression.

Specified by:
additionalDims in interface NewArray

additionalDims

public NewArray additionalDims(int addDims)
Set the number of additional dimensions of the expression.

Specified by:
additionalDims in interface NewArray

init

public ArrayInit init()
Get the initializer of the expression.

Specified by:
init in interface NewArray

init

public NewArray init(ArrayInit init)
Set the initializer of the expression.

Specified by:
init in interface NewArray

reconstruct

protected NewArray_c reconstruct(TypeNode baseType,
                                 java.util.List dims,
                                 ArrayInit init)
Reconstruct the expression.


visitChildren

public Node visitChildren(NodeVisitor v)
Visit the children of the expression.

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
Type check the expression.

Specified by:
typeCheck in interface NodeOps
Overrides:
typeCheck in class Node_c
Parameters:
tc - The type checking visitor.
Throws:

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.

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: Term
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:
