.SH NAME
UArray \- dynamic array class
.SH SYNOPSIS
.B #include <Unidraw/uarray.h>
.SH DESCRIPTION
UArray implements a dynamic array, that is, one that grows as elements
are added.  It can also act as a linked list, allowing insertion and
removal of objects, though the overhead for such operations is
generally greater than that for conventional doubly-linked list
implementations.  However, the overhead per stored object is
potentially much less for a UArray, and objects can be accessed by
index in constant time.
.SH PUBLIC OPERATIONS
.TP
.B "UArray(int = 16)"
Create a new UArray instance, optionally providing an estimate of its
maximum size.  While specifying the size is not required, supplying an
accurate estimate will improve performance.
.TP
.B "void*& operator[](int index)"
Overloading the brackets operator allows access to the UArray's
elements with the standard array notation.  Note that type information
is lost when retrieving objects from the UArray, requiring casting.
.TP
.B "void Insert(void*, int index)"
.ns
.TP
.B "void Remove(int index)"
Insert and remove an object at a particular index, moving the
succeeding objects up or down one position as required.
.TP
.B "int Index(void*)"
Return the given object's index in the UArray, returning \-1 if the
object does not appear in the UArray.
.TP
.B "int Count()"
Return the number of objects inserted in the UArray.
.TP
.B "void Clear()"
Clear the UArray, reducing the number of object it contains to zero.
