Layer Methods

The Layer type exposes the following members.

Methods
  NameDescription
Public methodCode exampleCommitChanges
Protected methodConstructConstObject
Assigns a parent object and a subobject index to this.
(Inherited from CommonObject.)
Public methodDefault
Sets layer to default settings.
Public methodDispose
Actively reclaims unmanaged resources that this instance uses.
(Inherited from CommonObject.)
Protected methodDispose(Boolean)
For derived class implementers.

This method is called with argument true when class user calls Dispose(), while with argument false when the Garbage Collector invokes the finalizer, or Finalize() method.

You must reclaim all used unmanaged resources in both cases, and can use this chance to call Dispose on disposable fields if the argument is true.

Also, you must call the base virtual method within your overriding method.

(Inherited from CommonObject.)
Public methodEnsurePrivateCopy
If you want to keep a copy of this class around by holding onto it in a variable after a command completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can call this function as many times as you want.
(Inherited from CommonObject.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Passively reclaims unmanaged resources when the class user did not explicitly call Dispose().
(Inherited from CommonObject.)
Public methodGetChildren
Gets immediate children of this layer. Note that child layers may have their own children.
Public methodStatic memberGetDefaultLayerProperties
Constructs a layer with the current default properties. The default layer properties are:

color = Rhino.ApplicationSettings.AppearanceSettings.DefaultLayerColor

line style = Rhino.ApplicationSettings.AppearanceSettings.DefaultLayerLineStyle

material index = -1

iges level = -1

mode = NormalLayer

name = empty

layer index = 0 (ignored by AddLayer)

Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetObjectData
Populates a System.Runtime.Serialization.SerializationInfo with the data needed to serialize the target object.
(Inherited from CommonObject.)
Public methodGetPersistentLocking
The persistent locking setting is used for layers that can be locked by a "parent" object. A common case is when a layer is a child layer (Layer.ParentI is not nil). In this case, when a parent layer is locked, then child layers are also locked. The persistent locking setting determines what happens when the parent is unlocked again.
Public methodGetPersistentVisibility
The persistent visbility setting is used for layers whose visibilty can be changed by a "parent" object. A common case is when a layer is a child layer (ParentId is not nil). In this case, when a parent layer is turned off, then child layers are also turned off. The persistent visibility setting determines what happens when the parent is turned on again.
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodGetUserString
Gets user string from this geometry.
Public methodGetUserStrings
Gets a copy of all (user key string, user value string) pairs attached to this geometry.
Public methodIsChildOf(Int32)
Public methodIsChildOf(Layer)
Public methodIsParentOf(Int32)
Public methodIsParentOf(Layer)
Public methodStatic memberCode exampleIsValidName
Determines if a given string is valid for a layer name.
Public methodIsValidWithLog
Determines if an object is valid. Also provides a report on errors if this object happens not to be valid.
(Inherited from CommonObject.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodNonConstOperation
For derived classes implementers.

Defines the necessary implementation to free the instance from being const.

(Inherited from CommonObject.)
Protected methodOnSwitchToNonConst
Is called when a non-const operation first occurs.
(Inherited from CommonObject.)
Public methodSetPersistentLocking
Set the persistent locking setting for this layer
Public methodSetPersistentVisibility
Set the persistent visibility setting for this layer
Public methodSetUserString
Attach a user string (key,value combination) to this geometry.
Public methodToString (Overrides ObjectToString.)
Public methodUnsetPersistentLocking
Remove any explicity persistent locking settings from this layer
Public methodUnsetPersistentVisibility
Remove any explicit persistent visibility setting from this layer
