DebugComponent

java.lang.Object
- com.facebook.litho.DebugComponent

```
public final class DebugComponent
extends Object
```
A DebugComponent represents a node in Litho's component hierarchy. DebugComponent removes the need to worry about implementation details of whether a node is represented by a Component or a ComponentLayout. The purpose of this class is for tools such as Stetho's UI inspector to be able to easily visualize a component hierarchy without worrying about implementation details of Litho.

- Method Detail
  - getRootInstance
```
public static DebugComponent getRootInstance(Component component)
```
    Returns:
    
    The root DebugComponent of a LithoView. This should be the start of your traversal.
  - getRootInstance
```
public static DebugComponent getRootInstance(LithoView view)
```
  - getRootInstance
```
public static DebugComponent getRootInstance(ComponentTree componentTree)
```
  - getRootInstance
```

```
  - setOverrider
```
public void setOverrider(DebugComponent.Overrider overrider)
```
  - getChildComponents
```
public List<DebugComponent> getChildComponents()
```
    Get the list of components composed by this component. This will not include any Views that are mounted by this component as those are not components. Use this#getMountedView for that.
    
    Returns:
    
    A list of child components.
  - getMountedView
```
public View getMountedView()
```
    Returns:
    
    A mounted view or null if this component does not mount a view.
  - getMountedDrawable
```
public Drawable getMountedDrawable()
```
    Returns:
    
    A mounted drawable or null if this component does not mount a drawable.
  - getLithoView
```
public LithoView getLithoView()
```
    Returns:
    
    The litho view hosting this component.
  - getBoundsInLithoView
```
public Rect getBoundsInLithoView()
```
    Returns:
    
    The bounds of this component relative to its hosting LithoView.
  - getBounds
```
public Rect getBounds()
```
    Returns:
    
    The bounds of this component relative to its parent.
  - isSameNode
```
public boolean isSameNode(DebugComponent other)
```
    Returns:
    
    True if this and given debug components share the same internal node
  - getContext
```
public ComponentContext getContext()
```
    Returns:
    
    the ComponentContext for this component.
  - isLayoutNode
```
public boolean isLayoutNode()
```
    Returns:
    
    True if this not has layout information attached to it (backed by a Yoga node)
  - getTestKey
```
public String getTestKey()
```
    Returns:
    
    This component's testKey or null if none is set.
  - getAllTextContent
```
public String getAllTextContent()
```
    Returns:
    
    A concatenated string of all text content within the underlying LithoView. Null if the node doesn't have an associated LithoView.
  - getTextContent
```
public String getTextContent()
```
    Returns:
    
    The text content of the component wrapped by the debug component, or null if no TextContent/TextView are found.
  - getComponentHost
```
public ComponentHost getComponentHost()
```
    Returns:
    
    The ComponentHost that wraps this component or null if one cannot be found.
  - getKey
```
public String getKey()
```
    Returns:
    
    This component's key or null if none is set.
  - getComponent
```
public Component getComponent()
```
    Returns:
    
    The Component instance this debug component wraps.
  - getLayoutNode
```
public DebugLayoutNode getLayoutNode()
```
    Returns:
    
    If this debug component represents a layout node, return it.
  - rerender
```
public void rerender()
```
  - getStateContainer
```
public StateContainer getStateContainer()
```
  - getGlobalKey
```
public String getGlobalKey()
```
  - canResolve
```
public boolean canResolve()
```
  - isRoot
