DebugComponent

- com.facebook.litho.DebugComponent

```
public final class DebugComponent
extends java.lang.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(LithoView view)
```
  - getRootInstance
```
public static DebugComponent getRootInstance(ComponentTree componentTree)
```
  - getInstance
```
public static DebugComponent getInstance(LithoLayoutResult result)
```
  - setOverrider
```
public void setOverrider(DebugComponent.Overrider overrider)
```
  - getChildComponents
```
public java.util.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.
  - getBoundsInParentDebugComponent
```
public Rect getBoundsInParentDebugComponent()
```
    The bounds of this component relative to its parent componen
    
    Returns:
  - 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 java.lang.String getTestKey()
```
    Returns:
    
    This component's testKey or null if none is set.
  - getComponentTestKey
```
public java.lang.String getComponentTestKey()
```
    Returns this component's testKey or null if none is set.
    Unlike getTestKey(), this function can return a test key set on any Component, including container Components which resolve into LayoutNodes.
    Unlike getTestKey(), this function can also return test keys set on individual Components even when they are all resolved into a single InternalNode.
  - getComponentTag
```
public java.lang.Object getComponentTag()
```
    Returns:
    
    This component's componentTag or null if none is set. Unlike getTestKey(), this will return tags for any Component, including Components which are not LayoutNodes.
  - getAllTextContent
```
public java.lang.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 java.lang.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 java.lang.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 java.lang.String getGlobalKey()
```
  - canResolve
```
public boolean canResolve()
```
  - isRoot
```
public boolean isRoot()
```
