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 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();
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();
