SimplexCache class
Used to warm start distance
. Set count to zero on first call.
class SimplexCache { /** length or area */ num metric; int count; /** vertices on shape A */ final List<int> indexA; /** vertices on shape B */ final List<int> indexB; /** * Constructs a new SimplexCache. */ SimplexCache() : metric = 0, count = 0, indexA = new List<int>(3), indexB = new List<int>(3) { for (int i = 0; i < 3; ++i) { indexA[i] = Settings.MAX_INTEGER; indexB[i] = Settings.MAX_INTEGER; } } /** * Sets this cache equal to the given cache. */ void setFrom(SimplexCache sc) { indexA.setRange(0, indexA.length, sc.indexA); indexB.setRange(0, indexB.length, sc.indexB); metric = sc.metric; count = sc.count; } }
Constructors
new SimplexCache() #
Constructs a new SimplexCache.
SimplexCache() : metric = 0, count = 0, indexA = new List<int>(3), indexB = new List<int>(3) { for (int i = 0; i < 3; ++i) { indexA[i] = Settings.MAX_INTEGER; indexB[i] = Settings.MAX_INTEGER; } }
Properties
int count #
int count;
final List<int> indexA #
vertices on shape A
final List<int> indexA;
final List<int> indexB #
vertices on shape B
final List<int> indexB;
num metric #
length or area
num metric;
final Type runtimeType #
A representation of the runtime type of the object.
external Type get runtimeType;
Operators
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);
Methods
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);
const Object() #
Creates a new Object
instance.
Object
instances have no meaningful state, and are only useful
through their identity. An Object
instance is equal to itself
only.
const Object();
void setFrom(SimplexCache sc) #
Sets this cache equal to the given cache.
void setFrom(SimplexCache sc) { indexA.setRange(0, indexA.length, sc.indexA); indexB.setRange(0, indexB.length, sc.indexB); metric = sc.metric; count = sc.count; }
new SimplexCache() #
Constructs a new SimplexCache.
SimplexCache() : metric = 0, count = 0, indexA = new List<int>(3), indexB = new List<int>(3) { for (int i = 0; i < 3; ++i) { indexA[i] = Settings.MAX_INTEGER; indexB[i] = Settings.MAX_INTEGER; } }
String toString() #
Returns a string representation of this object.
external String toString();
