collect

open fun collect(): List<A>

open fun collect(bounds: Interval): List<A>

connectTo

open fun <U : IntervalLike<U>> connectTo(other: ParallelOps<U, *>, connectToBounds: Boolean): Universal<Connection<A, U>>

(DOC) Creates an Universal object of Connections that associate of this timeline's object to the (chronologically) next object in another timeline that starts after this one ends.

convert

open fun <RESULT : GeneralOps<A, RESULT>> convert(ctor: (Timeline<A, RESULT>) -> RESULT): RESULT

(DOC) Safely converts to another timeline type that accepts the same payload type.

countActive

open fun countActive(): Numbers<Int>

(DOC) Returns a Numbers profile that corresponds to the number of active objects at any given time.

ends

open fun ends(): THIS

filter

open fun filter(preserveMargin: Boolean = false, f: (A) -> Boolean): THIS

(DOC) Removes or retains objects based on a predicate.

filterByDuration

open fun filterByDuration(validInterval: Interval): THIS

(DOC) Removes objects whose duration is outside a given valid interval.

filterByType

open fun filterByType(vararg types: String): THIS

Filters out all activities except those of a given vararg list of types.

open fun filterByType(types: List<String>): THIS

Filters out all activities except those of a given list of types.

filterByWindows

open fun filterByWindows(windows: SerialOps<Interval, *>, truncateMarginal: Boolean = true): THIS

filterLongerThan

open fun filterLongerThan(dur: Duration): THIS

(DOC) Removes objects whose duration is shorter than a given duration.

filterShorterThan

open fun filterShorterThan(dur: Duration): THIS

(DOC) Removes objects whose duration is longer than a given duration.

flattenIntoProfile

open fun <R : Any, RESULT : SerialSegmentOps<R, RESULT>> flattenIntoProfile(ctor: (Timeline<Segment<R>, RESULT>) -> RESULT, f: (A) -> R): RESULT

(DOC) Converts the payload objects into segments and flattens them into a serial profile.

forEach

open fun forEach(p0: Consumer<in A>)

highlight

open fun highlight(f: (A) -> Boolean): Windows

(DOC) Similar to filter, but produces a coalesced Windows object that highlights everything that satisfies the predicate.

highlightAll

open fun highlightAll(): Windows

(DOC) Highlights all objects in the timeline in a new Windows timeline.

inspect

open fun inspect(f: Consumer<List<A>>): THIS

(DOC) Inserts a no-op function into the operation stack to allow side effects, such as printing.

isolate

open fun isolate(f: (A) -> Boolean): Universal<A>

(DOC) Similar to filter, but returns an Universal timeline.

iterator

abstract operator fun iterator(): Iterator<A>

merge

open infix fun merge(i: A): THIS

(DOC) Combines this timeline with a single payload object by overlaying them.

open infix fun merge(other: GeneralOps<A, *>): THIS

(DOC) Combines two timelines together by overlaying them. Does not perform any transformation.

reduceIntoProfile

open fun <R : Any, RESULT : SerialSegmentOps<R, RESULT>> reduceIntoProfile(ctor: (Timeline<Segment<R>, RESULT>) -> RESULT, op: NullBinaryOperation<A, R, R>): RESULT

(DOC) Converts the payload objects into segments and combines them into a serial profile.

rollingDuration

open fun rollingDuration(range: Duration, unit: Duration): Real

(DOC) Calculates the sum of durations of objects in a range leading the current time.

select

open fun select(interval: Interval): THIS

(DOC) Restricts the timeline to only be evaluated in the given interval.

shift

open fun shift(dur: Duration): THIS

(DOC) Uniformly shifts the entire timeline in time (positive shifts toward the future).

shiftEndpoints

open fun shiftEndpoints(shiftStart: Duration, shiftEnd: Duration = shiftStart): THIS

(DOC) Shifts the start and end points of each object.

spliterator

open fun spliterator(): Spliterator<A>

starts

open fun starts(): THIS

(DOC) Truncates each object to only its start time.

unsafeCast

abstract fun <RESULT : Timeline<A, RESULT>> unsafeCast(ctor: (Timeline<A, RESULT>) -> RESULT): RESULT

(DOC) UNSAFE! Casts this timeline type to another type without changing its contents.

unsafeFlatMap

open fun <R : IntervalLike<R>, RESULT : GeneralOps<R, RESULT>> unsafeFlatMap(ctor: (Timeline<R, RESULT>) -> RESULT, boundsTransformer: BoundsTransformer, truncate: Boolean, f: (A) -> Segment<GeneralOps<R, *>>): RESULT
