new ImageLoader(Iterable<String> urls) #
ImageLoader(Iterable<String> urls) : super(urls);
Methods
bool operator ==(other) #
The equality operator.
The default behavior for all Object
s 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.
bool operator ==(other) => identical(this, other);
int get completedBytes() #
int get completedBytes { return _entries.selectNumbers((e) => e.completedBytes).sum(); }
int get completedCount() #
int get completedCount => _entries.count((e) => e.completed);
T getResource(String url) #
T getResource(String url) => _getByUrl(url).resource;
int hashCode() #
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.
external int hashCode();
void load() #
void load() { assert(_state == StateUnloaded); _state = StateLoading; for(final e in _entries) { _httpLoad(e.url); } }
noSuchMethod(String name, List args) #
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
. If noSuchMethod
returns a value, that value becomes the result of the original
invocation.
The default behavior of noSuchMethod
is to throw a
noSuchMethodError
.
external Dynamic noSuchMethod(String name, List args);
Type get runtimeType() #
A representation of the runtime type of the object.
external Type get runtimeType;
String toString() #
Returns a string representation of this object.
external String toString();
int get totalBytes() #
int get totalBytes { return _entries.selectNumbers((e) { if(e.totalBytes == null) { return _defaultSize; } else { return e.totalBytes; } }).sum(); }
