public final class HighlightsLayer extends Object
There can be multiple highlight layers participating in rendering one document. Each highlight layer provides its z-order, which defines an order in which the layers are used. The higher the z-order the more 'visible' the layer is. In other word highlights provided by a layer with higher z-order can hide highlights provided by a layer with lower z-order for the same part of a document.
The highlights provided by a
define any attributes affecting text rendering including attributes that affect the
size of the view containing the rendered text. The layers that use those attributes
have to participate in the view layout and therefore need to be treated in a
special way. The
isFixedSize attribute can be
if and only if layer's highlights will never contain attributes that influence the
layout of a view (e.g. font size).
