Field Detail

type

public Type type

The type of the elements being given zero-default values, or (if an array initializer is present), the type of the array initializer elements.

E.g., new int[4][3][] yields a type of int[] and new int[][][]{a, b} yields a type of int[][].

init

public ArrayInit init

The array initializer, if any. If it is present then dims will contain exactly 1 element, the inferred size of the array initializer.

E.g., new int[][]{7, 5} will generate a dims of {INTLIT(2)}.

dims

public ExprVec dims

If init is null, then holds Expr's between []'s in order. If init is not null, then holds the inferred array size. (cf. init). E.g., new int[x+y][z][] will generate a dims of {, }.

loc

public int loc

locOpenBrackets

public int[] locOpenBrackets

The locations of the open brackets for each Expr (possibly inferred if init != null) in dims.

The open bracket in front of dims[i] is located at locOpenBrackets[i].

Note:

locOpenBrackets may contain junk after the first dims.size() entries.

Method Detail

getStartLoc

public int getStartLoc()

Specified by:

getStartLoc in class ASTNode

getEndLoc

public int getEndLoc()

Overrides:

getEndLoc in class ASTNode

postCheck

private void postCheck()

make

public static NewArrayExpr make(Type type,
                                ExprVec dims,
                                ArrayInit init,

                                int[] locOpenBrackets)

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

getTag

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

accept in class ASTNode

check

public void check()

Overrides:

check in class Expr
