Let's look at how we can make that work.

## pytest.mark.anyio { #pytest-mark-anyio }

        // Initial update - should mark as changed
        entry.updateChild(childName, 1024L, 1000L, false, 0x20, 500L, 800L);
        assertTrue(entry.hasChanges());

        // Clear changes to test next scenario
        entry.markComplete();
        assertFalse(entry.hasChanges());

        // Update with same values - should not mark as changed (no actual change)

     * @return true if completed, false otherwise
     */
    public boolean isCompleted() {
        return completed;
    }

    /**
     * Mark request as completed
     */
    public void markCompleted() {
        this.completed = true;
    }

    /**
     * Mark request as failed with error
     *
     * @param error exception that caused the failure
     */
    public void markFailed(Exception error) {

## Deprecate a *path operation* { #deprecate-a-path-operation }

If you need to mark a *path operation* as <abbr title="obsolete, recommended not to use it">deprecated</abbr>, but without removing it, pass the parameter `deprecated`:

}

// encodeMarker will encode a uuid and return it as a marker.
// uuid cannot contain '[', ':' or ','.
func (o listPathOptions) encodeMarker(marker string) string {
	if o.ID == "" {
		// Mark as returning listing...
		return fmt.Sprintf("%s[minio_cache:%s,return:]", marker, markerTagVersion)
	}
	if strings.ContainsAny(o.ID, "[:,") {

        // Test isDeleted method
        StopwordsItem item = new StopwordsItem(1, "word");
        assertFalse(item.isDeleted());

        item.setNewInput("new");
        assertFalse(item.isDeleted());

        // Mark for deletion with empty string
        item.setNewInput("");
        assertTrue(item.isDeleted());

        item.setNewInput(null);
        assertFalse(item.isDeleted());
    }

So, you import `Query`, which is a function. And when you call it, it returns an instance of a class also named `Query`.

These functions are there (instead of just using the classes directly) so that your editor doesn't mark errors about their types.

That way you can use your normal editor and coding tools without having to add custom configurations to disregard those errors.

	found := make(map[string]struct{}, len(d.Cache))

	// Mark all children recursively
	var mark func(entry dataUsageEntry)
	mark = func(entry dataUsageEntry) {
		for k := range entry.Children {
			found[k] = struct{}{}
			if ch, ok := d.Cache[k]; ok {
				mark(ch)
			}
		}
	}
	found[top] = struct{}{}
	mark(*topE)

	// Delete all entries not found.
	for k := range d.Cache {

        totalAllocated.incrementAndGet();

        log.trace("Registered resource: {} ({})", resourceId, resource.getClass().getSimpleName());

        return resourceId;
    }

    /**
     * Mark a resource as closed
     *
     * @param resourceId the resource ID
     */
    public void markClosed(String resourceId) {
        ResourceHolder holder = activeResources.get(resourceId);

The way to describe this in OpenAPI, is to mark that field as **required**, because it will always be there.

Because of that, the JSON Schema for a model can be different depending on if it's used for **input or output**:
