HatchPattern Class

Gets or sets the component status of the model component.

Gets the name of a component that is deleted.

Indicates if this object has been disposed or the document it originally belonged to has been disposed.

Returns a value indicating whether the component has an ID.

Returns a value indicating whether the component has an Index.

Returns a value indicating whether the component has a Name.

Gets true if this class has any custom information attached to it through UserData.

Gets or sets the ID of the current instance.

Returns a value indicating whether the component ID is already locked.

Returns a value indicating whether the component Index is already locked.

The component status itself can be locked. This returns an indication.

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.

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

Tests an object to see if it is valid.

Returns a value indicating whether the component Name is already locked.

List of custom information that is attached to this class.

Dictionary of custom information attached to this class. The dictionary is actually user data provided as an easy to use sharable set of information.

Resets the HasId property of the model component to false, if possible.

Resets the HasIndex property of the model component to false, if possible.

Resets the HasName property of the model component to false, if possible.

Assigns a parent object and a subobject index to this.

Increments the Cyclic Redundancy Check value by this instance.

Actively reclaims unmanaged resources that this instance uses.

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.

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.

Passively reclaims unmanaged resources when the class user did not explicitly call Dispose().

Populates a System.Runtime.Serialization.SerializationInfo with the data needed to serialize the target object.

Determines if an object is valid. Also provides a report on errors if this object happens not to be valid.

Locks the component Id property.

Locks the component Index property.

Locks the component Name property.

For derived classes implementers.

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

Is called when a non-const operation first occurs.

Returns the name of the model component type, and then its name and index.
