ContactID class

Contact ids to facilitate warm starting. Basically just containers for an individual Features object that contains interesting information.

class ContactID {
  /** The features that intersect to form the contact point */
  final Features features;

  /**
   * Constructs a new ContactID. */
  ContactID() : features = new Features();

  /**
   * Constructs a ContactID that is a copy of the given ContactID.
   */
  ContactID.copy(ContactID other) :
    features = new Features.copy(other.features);

  /**
   * Returns true if this ContactID equals the given ContactID.
   */
  bool operator ==(other) => other.features == features;

  /**
   * Sets this contactID to be equal to the given ContactID.
   */
  void setFrom(ContactID other) { features.setFrom(other.features); }

  /**
   * Returns true if this ContactID equals the given ContactID.
   */
  bool isEqual(ContactID other) => other.features == features;

  /**
   * Zeroes out the data.
   */
  void zero() { features.zero(); }
}

Constructors

new ContactID() #

Constructs a new ContactID.

ContactID() : features = new Features();

new ContactID.copy(ContactID other) #

Constructs a ContactID that is a copy of the given ContactID.

ContactID.copy(ContactID other) :
  features = new Features.copy(other.features);

Properties

final Features features #

The features that intersect to form the contact point

final Features features;

final Type runtimeType #

inherited from Object

A representation of the runtime type of the object.

external Type get runtimeType;

Operators

bool operator ==(other) #

Returns true if this ContactID equals the given ContactID.

bool operator ==(other) => other.features == features;

Methods

new ContactID() #

Constructs a new ContactID.

ContactID() : features = new Features();

new ContactID.copy(ContactID other) #

Constructs a ContactID that is a copy of the given ContactID.

ContactID.copy(ContactID other) :
  features = new Features.copy(other.features);

int hashCode() #

inherited from Object

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();

bool isEqual(ContactID other) #

Returns true if this ContactID equals the given ContactID.

bool isEqual(ContactID other) => other.features == features;

noSuchMethod(String name, List args) #

inherited from Object

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() #

inherited from 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(ContactID other) #

Sets this contactID to be equal to the given ContactID.

void setFrom(ContactID other) { features.setFrom(other.features); }

String toString() #

inherited from Object

Returns a string representation of this object.

external String toString();

void zero() #

Zeroes out the data.

void zero() { features.zero(); }
