<br>
</div>A "Heap" is also known as a "Priority Queue". So the interface must be similar.<br>
<br>
I have nothing against this (*), although the spec leaves out a few corner cases. E.g., what happens when the keys are equal, but the values/content associated are not?<br></blockquote><div><br></div><div>That is unclear in the specification. The example implementations would do different things depending on if you use something that is (essentially) "less than" or "less than or equal" (in the former case, they'd not re-order the equal values whenever there's an operation on the queue, in the latter case, they would).</div>
<div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Apart from that, I do not understand the use of DECLARE-HEAP and I believe that there should be no provisions to define a package for these sort of data structures.

</blockquote><div><br></div><div>That is definitely something that is worth discussing. The main reason fro submitting GENHEAP is that I didn't see anything similar and, well, I did submit GENHASH back in the early days of CDRs.

<div><br></div><div>The main reason for DECLARE-HEAP is to allow for the example implementation that defines all underlying operations in terms of methods on a specialized class to be easily created on "this is the type of heap I want" rather than on the first creation.</div>
