Method Detail

isDiscardable

public boolean isDiscardable()

Overrides:

isDiscardable in class RenderNode

isIgnorableForRendering

public boolean isIgnorableForRendering()

If that method returns true, the element will not be used for rendering. For the purpose of computing sizes or performing the layouting (in the validate() step), this element will treated as if it is not there.

If the element reports itself as non-empty, however, it will affect the margin computation.

Overrides:

isIgnorableForRendering in class RenderNode

Returns:

isEmpty

public boolean isEmpty()

Overrides:

isEmpty in class RenderNode
