TimeRanges class / dart:html Library / Dart API Reference

TimeRanges class

The TimeRanges interface is used to represent a set of time ranges, primarily for the purpose of tracking which portions of media have been buffered when loading it for use by the <audio> and <video> elements.

A TimeRanges object includes one or more ranges of time, each specified by a starting and ending time offset. You reference each time range by using the start() and end() methods, passing the index number of the time range you want to retrieve.

Properties

final int hashCode #

inherited from Interceptor

Get a hash code for this object.

All objects have hash codes. Hash codes are guaranteed to be the same for objects that are equal when compared using the equality operator ==. Other than that there are no guarantees about the hash codes. They will not be consistent between runs and there are no distribution guarantees.

If a subclass overrides hashCode it should override the equality operator as well to maintain consistency.

docs inherited from Object

int get hashCode => Primitives.objectHashCode(this);

final int length #

The number of time ranges represented by the time range object. Read only.

from MDN

final int length

final Type runtimeType #

inherited from Interceptor

A representation of the runtime type of the object.

docs inherited from Object

Type get runtimeType => getRuntimeType(this);

Operators

bool operator ==(other) #

inherited from Interceptor

The equality operator.

The default behavior for all Objects is to return true if and only if this and other are the same object.

If a subclass overrides the equality operator it should override the hashCode method as well to maintain consistency.

docs inherited from Object

bool operator ==(other) => identical(this, other);

Methods

num end(int index) #

Returns the time for the end of the specified range.

from MDN

@DomName('TimeRanges.end')
@DocsEditable
num end(int index) native;

dynamic noSuchMethod(Invocation invocation) #

inherited from Interceptor

noSuchMethod is invoked when users invoke a non-existant method on an object. The name of the method and the arguments of the invocation are passed to noSuchMethod in an Invocation. If noSuchMethod returns a value, that value becomes the result of the original invocation.

The default behavior of noSuchMethod is to throw a noSuchMethodError.

docs inherited from Object

dynamic noSuchMethod(Invocation invocation) {
 throw new NoSuchMethodError(
     this,
     _symbolToString(invocation.memberName),
     invocation.positionalArguments,
     _symbolMapToStringMap(invocation.namedArguments));
}

num start(int index) #

Returns the time for the start of the range with the specified index.

from MDN

@DomName('TimeRanges.start')
@DocsEditable
num start(int index) native;

String toString() #

inherited from Interceptor

Returns a string representation of this object.

docs inherited from Object

String toString() => Primitives.objectToString(this);
