bool

Layer.__eq__(layer)
Return type

bool

Layer.out_point([view=View( 0 )])
Return type

uint

Parameters

view (View) – View.

Returns out-point value for given view.

Layer.parameter(name_components)
Return type

Parameter

Parameters

name_components (list of strings) – Relative name for a requested parameter.

Returns Parameter instance bound with given name path.

Layer.parameter_set([name_components=list()])
Return type

ParameterSet

Parameters

name_components (list of strings) – Relative name for a requested parameter set.

Returns ParameterSet instance bound with given name path. Pass an empty list [] to get access to the Layer parameters set.

Layer.remove()

Removes current layer.

Layer.set_parent(group[, index=0])
Parameters
  • group (LayerGroup) – New parent group.

  • index (uint) – Insertion index.

Moves the layer object to the certain group. Pass None to move it to the top level.
