Interface TimelineModel

All Known Implementing Classes:

TimelineModelImpl

public interface TimelineModel

Timeline model which holds timeline bounds, interval and animation flags.

The timeline controls the currently selected time interval, accessible in the DynamicAPI. When enabled, it maintains the time scale and the position of the interval.

It also holds configuration values for animation such as speed and step size.

Method Detail

isEnabled

boolean isEnabled()

Returns true if the timeline is enabled. When enabled, the timeline is filtering the current graph.

Returns:

true if the timeline is enabled, false otherwise

getMin

double getMin()

Returns the min value of the time scale. This is the start of the earliest interval in the workspace.

Returns:

the min

getMax

double getMax()

Returns the max value of the time scale. This is the end of the latest interval in the workspace.

Returns:

the max

getCustomMin

double getCustomMin()

Returns the custom min value. This value can't be inferior than min

Returns:

the custom min

getCustomMax

double getCustomMax()

Returns the custom max value. This value can't be superior than max

Returns:

the custom max

hasCustomBounds

boolean hasCustomBounds()

Returns true if custom bounds are defined. Returns false when custom bounds are equal to min and max.

Returns:

true if custom bounds are defined, false otherwise.

hasValidBounds

boolean hasValidBounds()

Returns true if none of the min and max time values are infinity.

Returns:

true if the time scale is valid, false otherwise

getIntervalStart

double getIntervalStart()

Returns the lower bound of the interval.

Returns:

the interval start

getIntervalEnd

double getIntervalEnd()

Returns the upper bound of the interval.

Returns:

the interval end

getTimeFormat

DynamicModel.TimeFormat getTimeFormat()

Returns the current time format. Default is DOUBLE

Returns:

the current tie

getPlayDelay

int getPlayDelay()

Returns the play delay in milliseconds. Defines the time between each interval shift.

Returns:

the play delay

getPlayStep

double getPlayStep()

Returns the play step. Defines how much the interval is moved at each step during animation. Defined in percentage of the total interval.

Returns:

the play step

isPlaying

boolean isPlaying()

Returns true if the timeline is playing.

Returns:

true is playing, false otherwise

getPlayMode

TimelineModel.PlayMode getPlayMode()

Returns the play mode. This defines how the interval is moved.

Returns:

the play mode

getChart

TimelineChart getChart()

Returns the current timeline chart or null if node.

Returns:

the timeline chart or null
