Methods

getPath

(): GeneralPath
abstract
Returns a representation of the visible path of the edge in the form of a GeneralPath

getSegmentCount

(): number
abstract
Returns the number of "segments" this edge's path consists of.

getTangent

(ratio: number): Tangent
abstract
Calculates the tangent on the edge's path at the given ratio point.
Implementers are not required to return a tangent with normalized vector, and therefore callers should not expect to receive a tangent with normalized vector.
abstract

Parameters

ratio: number
a value in [0,1] where 0 is the source's end and 1 is at the target's end of the visible edge path

Return Value

Tangent
The tangential line, if any exists.

getTangentForSegment

(segmentIndex: number, ratio: number): Tangent
abstract
Calculates the tangent on the edge's path at the given ratio point for the given segment.
Implementers are not required to return a tangent with normalized vector, and therefore callers should not expect to receive a tangent with normalized vector.
abstract

Parameters

segmentIndex: number
The segment to use for the calculation
ratio: number
A value in [0,1] where 0 is the source's end and 1 is at the target's end of the segment

Return Value

Tangent
The tangential line, if any exists.
