Class: QgsMapLayerStyle

• it is only possible to read or write layer’s current style.

Methods

isValid	Tell whether the style is valid (i.e. there is something stored in it).
readFromLayer	Store layer's active style information in the instance
readXml	Read style configuration (for project file reading)
writeToLayer	Apply stored layer's style information to the layer
writeXml	Write style configuration (for project file writing)
xmlData	Returns XML content of the style
