NAME

Math::Geometry::Construction::Vector - anything representing a vector

VERSION

Version 0.024

DESCRIPTION

The typical user will not interact directly with this class. It unifies the access to different sources of a vector. This can be

• a reference to an array of numbers

  In this case, the value method will return a Math::Vector::Real object consisting of the first two items of the array. It is only checked if the type is the Moose type ArrayRef[Num]. It is not checked if the array contains at least two items.

• a Math::Vector::Real object

  The value method returns the object itself (not a clone).

• a Math::VectorReal object

  The value method returns an Math::Vector::Real object consisting of the x and y component of the vector.

• a Math::Geometry::Construction::Point object

  The value method returns the position attribute of the point.

• a Math::Geometry::Construction::Line object

  The value method returns the direction of the line.

Point and Line objects are evaluated at the time you call value.

INTERFACE

Constructors

new

$vector = Math::Geometry::Construction::Vector->new
    (provider => ...)

Creates a new Math::Geometry::Construction::Vector object and initializes attributes. This is the default Moose constructor.

Public Attributes

provider

This is the only attribute. It must be set at construction time and is readonly after that. The possible values are described in the DESCRIPTION section.

Methods

value

Returns a Math::Vector::Real object as described in the DESCRIPTION section.
