Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`protected void`	`checkAndAddToParent()` Called recursively when a property has been set in the item. This is mandatory because it could happen that the parent item is not present, therefore it must be added.
`CapStyle`	`getBorderCapStyle()` Returns how the end points of every line are drawn.
`List<Integer>`	`getBorderDash()` Returns the line dash pattern used when stroking lines, using an array of values which specify alternating lengths of lines and gaps which describe the pattern.
`int`	`getBorderDashOffset()` Returns the line dash pattern offset or "phase".
`JoinStyle`	`getBorderJoinStyle()` Returns how two connecting segments (of lines, arcs or curves) with non-zero lengths in a shape are joined together (degenerate segments with zero lengths, whose specified end points and control points are exactly at the same position, are skipped). There are three possible values for this property: round, bevel and miter.

public CubicInterpolationMode getCubicInterpolationMode()
```
