expr

public Expr expr
Constructor Detail

LabelExpr

protected LabelExpr()
Construct a raw LabelExpr whose class invariant(s) have not yet been established. It is the caller's job to initialize the returned node's fields so that any class invariants hold.

Method Detail

childCount

public final int childCount()
Description copied from class: GCExpr
Return the number of children a node has.

Specified by:
childCount in class GCExpr

childAt

public final java.lang.Object childAt(int index)
Description copied from class: GCExpr
Return the first-but-ith child of a node.

Specified by:
childAt in class GCExpr

toString

public final java.lang.String toString()
Description copied from class: GCExpr
Return a string representation of this. Meant for debugging use only, not for presentation.

Specified by:
toString in class GCExpr

getTag

public final int getTag()
Description copied from class: GCExpr
Return the tag of a node.

Specified by:
getTag in class GCExpr

accept

public final void accept(Visitor v)
Description copied from class: GCExpr
Accept a visit from v. This method simply calls the method of v corresponding to the allocated type of this, passing this as the argument. See the design patterns book.

Specified by:
accept in class GCExpr

accept

public final java.lang.Object accept(VisitorArgResult v,
                                     java.lang.Object o)
Specified by:
accept in class GCExpr

check

public void check()
Overrides:
check in class GCExpr

make

public static LabelExpr make(int sloc,
                             int eloc,
                             boolean positive,
                             Identifier label,
                             Expr expr)
