Modifier and Type	Method	Description
`abstract void`	`component(Component component, org.apache.wicket.util.visit.IVisit<Void> visit)`
`abstract boolean`	`preCheck(Component component)`	In order to find the deepest component, we traverse downwards starting from the root (e.g.
`org.apache.wicket.util.visit.Visit<Void>`	`visit(Component rootComponent)`	Render the child hierarchy headers.
`org.apache.wicket.util.visit.Visit<Void>`	`visit(Component rootComponent, org.apache.wicket.util.visit.Visit<Void> visit)`	Render the child hierarchy headers.

public DeepChildFirstVisitor()
```
    Construct.
- Method Detail
  - visit
```
public final org.apache.wicket.util.visit.Visit<Void> visit(Component rootComponent)
```
    Render the child hierarchy headers.
    
    Parameters:
    
    rootComponent -
    
    Returns:
    
    The object return by component()
  - visit
```
public final org.apache.wicket.util.visit.Visit<Void> visit(Component rootComponent,
                                                            org.apache.wicket.util.visit.Visit<Void> visit)
```
    Render the child hierarchy headers.
    
    Parameters:
    
    rootComponent -
    
    visit -
    
    Returns:
    
    The object return by component()
  - component
```
public abstract void component(Component component,
                               org.apache.wicket.util.visit.IVisit<Void> visit)
```
    Specified by:
    
    component in interface org.apache.wicket.util.visit.IVisitor<Component,Void>
  - preCheck
```
public abstract boolean preCheck(Component component)
```
    In order to find the deepest component, we traverse downwards starting from the root (e.g. Page). However, once a component is not disabled (preCheck() returns false), iteration will stop and traversal continues with the sibling.
    
    Parameters:
    
    component - The component to be tested
    
    Returns:
    
    True, if component is enabled
