# RandomDirection¶

class RandomDirection(*args)

Sampling following the random direction strategy.

Available constructor:

RandomDirection()

RandomDirection(dimension)

Parameters: dimension : integer The dimension of the standard space. By default, but automatically updated by the calling class.

Notes

The RandomDirection strategy is the following : we generate some points on the sphere unity in the standard space according to the uniform distribution and we consider both opposite directions so built.

Methods

 generate() Generate the sample. getClassName() Accessor to the object’s name. getDimension() Accessor to the dimension. getId() Accessor to the object’s id. getName() Accessor to the object’s name. getShadowedId() Accessor to the object’s shadowed id. getUniformUnitVectorRealization(*args) Accessor to a realization according to the uniform distribution. getVisibility() Accessor to the object’s visibility state. hasName() Test if the object is named. hasVisibleName() Test if the object has a distinguishable name. setDimension(dimension) Accessor to the dimension. setName(name) Accessor to the object’s name. setShadowedId(id) Accessor to the object’s shadowed id. setVisibility(visible) Accessor to the object’s visibility state.
__init__(*args)

Initialize self. See help(type(self)) for accurate signature.

generate()

Generate the sample.

Returns: sample : Sample The sample generated in two opposite random directions.
getClassName()

Accessor to the object’s name.

Returns: class_name : str The object class name (object.__class__.__name__).
getDimension()

Accessor to the dimension.

Returns: dimension : int Dimension of the standard space.
getId()

Accessor to the object’s id.

Returns: id : int Internal unique identifier.
getName()

Accessor to the object’s name.

Returns: name : str The name of the object.
getShadowedId()

Accessor to the object’s shadowed id.

Returns: id : int Internal unique identifier.
getUniformUnitVectorRealization(*args)

Accessor to a realization according to the uniform distribution.

Parameters: dimension : int The dimension of the sphere unity (which is the dimension of the standard space). sample : Point The realization of a vector on the sphere unity, according to the uniform distribution.
getVisibility()

Accessor to the object’s visibility state.

Returns: visible : bool Visibility flag.
hasName()

Test if the object is named.

Returns: hasName : bool True if the name is not empty.
hasVisibleName()

Test if the object has a distinguishable name.

Returns: hasVisibleName : bool True if the name is not empty and not the default one.
setDimension(dimension)

Accessor to the dimension.

Parameters: dimension : int Dimension of the standard space.
setName(name)

Accessor to the object’s name.

Parameters: name : str The name of the object.
setShadowedId(id)

Accessor to the object’s shadowed id.

Parameters: id : int Internal unique identifier.
setVisibility(visible)

Accessor to the object’s visibility state.

Parameters: visible : bool Visibility flag.
