Properties
True if the content is automatically deleted when not in use.
ComponentStatus
Gets or sets the component status of the model component.
Returns ModelComponentType.RenderContent.
Overrides: ModelComponent.ComponentType
Disposed
Indicates if this object has been disposed or the document it originally belonged to has been disposed.
The parent File3dm of the entire hierarchy.
HasUserData
Gets true if this class has any custom information attached to it through UserData.
Exceptions:
| InvalidOperationException | When setting the ID failed. This usually happened because the instance ID is already locked. |
IdIsLocked
Returns a value indicating whether the component ID is already locked.
Exceptions:
| InvalidOperationException | When setting the Index failed. This usually happens because the instance Index is already locked. |
IndexIsLocked
Returns a value indicating whether the component Index is already locked.
InstanceDefinitionModelSerialNumber
When a component is in a model as part of the information required for a linked instance definition, this value identifies the linked instance definition reference model.
Remarks: Reference components are not saved in .3dm archives. Typically this value is set and locked by the code that adds a component to a model. This value is not saved in .3dm archives.
True if this is a child of another render content (i.e., has a parent; is not top-level).
IsComponentStatusLocked
The component status itself can be locked. This returns an indication.
IsDeleted
true if the component is deleted. Deleted components are kept by the document for undo purposes.
IsDocumentControlled
If true this object may not be modified. Any properties or functions that attempt to modify this object when it is set to "IsReadOnly" will throw a NotSupportedException.
IsReference
Gets a value indicting whether this component is a referenced component. Referenced components are part of referenced documents.
IsSystemComponent
True if this model component is a system constant.
An incomplete list of system constant model components is below:
- ON_ModelComponent::Unset
- ON_InstanceDefinition::Empty
- ON_Linetype::Unset
- ON_Linetype::Continuous
- ON_Linetype::ByLayer
- ON_Linetype::ByParent
- ON_Layer::Unset
- ON_Layer::Default
- ON_TextStyle::Unset
- ON_TextStyle::Default
- ON_TextStyle::ByLayer
- ON_TextStyle::ByParent
- ON_DimStyle::Unset
- ON_DimStyle::Default
- ON_DimStyle::DefaultInchDecimal
- ON_DimStyle::DefaultInchFractional
- ON_DimStyle::DefaultFootInchArchitecture
- ON_DimStyle::DefaultMillimeterSmall
- ON_DimStyle::DefaultMillimeterLarge
- ON_DimStyle::DefaultMillimeterArchitecture
True if this is a top-level render content (i.e., has no parent; is not a child).
ModelSerialNumber
A value identifying the model that manages this component.
Remarks: If the component is being managed by a model, this value identifies the model. In Rhino, this value is the document runtime serial number. Typically this value is set and locked by the code that adds a component to a model. This value is not saved in .3dm archives.
Exceptions:
| InvalidOperationException | When setting the Name failed. This usually happens because the instance Name is already locked. |
NameIsLocked
Returns a value indicating whether the component Name is already locked.
The parent content or null if this is the top level object.
ReferenceModelSerialNumber
When a component is in a model for reference, this value identifies the reference model.
Remarks: Reference components are not saved in .3dm archives. Typically this value is set and locked by the code that adds a component to a model. This value is not saved in .3dm archives.
The top-level parent content. Returns this if this is the top-level item.
UserData
List of custom information that is attached to this class.
UserDictionary
Dictionary of custom information attached to this class. The dictionary is actually user data provided as an easy to use shareable set of information.
Methods
True if a particular child slot is 'on'.
Parameters:
| child_slot_name (string) |
ClearId
public void ClearId()
Resets the HasId property of the model component to false, if possible.
Exceptions:
| InvalidOperationException | If the ID is locked. |
ClearIndex
public void ClearIndex()
Resets the HasIndex property of the model component to false, if possible.
Exceptions:
| InvalidOperationException | If the index is locked. |
ClearName
public void ClearName()
Resets the HasName property of the model component to false, if possible.
Exceptions:
| InvalidOperationException | If the name is locked. |
ConstructConstObject
Assigns a parent object and a sub-object index to this.
DataCRC
Increments the Cyclic Redundancy Check value by this instance.
Parameters:
| currentRemainder (uint) | The current remainder value. |
Returns: The updated remainder value.
Deletes any existing child with the specified child slot name. True if successful, else false.
Parameters:
| child_slot_name (string) |
Dispose
public void Dispose()
Actively reclaims unmanaged resources that this instance uses.
Dispose
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.
Parameters:
| disposing (bool) | true if the call comes from the Dispose() method; false if it comes from the Garbage Collector finalizer. |
EnsurePrivateCopy
public void EnsurePrivateCopy()
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.
The child with the specified child slot name, or null if no such child exists.
Parameters:
| child_slot_name (string) |
GetObjectData
[SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.SerializationFormatter)]
public virtual void GetObjectData(SerializationInfo info, StreamingContext context)
Populates a System.Runtime.Serialization.SerializationInfo with the data needed to serialize the target object.
Parameters:
| info (SerializationInfo) | The System.Runtime.Serialization.SerializationInfo to populate with data. |
| context (StreamingContext) | The destination (see System.Runtime.Serialization.StreamingContext) for this serialization. |
Gets a named parameter. The parameter value or null if not found.
Parameters:
| param (string) |
IsValidWithLog
Determines if an object is valid. Also provides a report on errors if this object happens not to be valid.
Parameters:
| log (out string) | A textual log. This out parameter is assigned during this call. |
Returns: true if this object is valid; false otherwise.
LockId
public void LockId()
Locks the component Id property.
LockIndex
public void LockIndex()
Locks the component Index property.
LockName
public void LockName()
Locks the component Name property.
NonConstOperation
protected virtual void NonConstOperation()
For derived classes implementers.
Defines the necessary implementation to free the instance from being constant.
OnSwitchToNonConst
protected virtual void OnSwitchToNonConst()
Is called when a non-constant operation first occurs.
Sets a named parameter. True if the parameter was set, else false.
ToJSON
Create a JSON string representation of this object
Parameters:
| options (SerializationOptions) |
ToString
Returns the name of the model component type, and then its name and index.
Remarks: This is provided as a visual aid. Do not rely on this for serialization.
Overrides: Object.ToString
