} ``` #### Property Value [bool](https://learn.microsoft.com/dotnet/api/system.boolean) ### Type Gets or sets the type. ```csharp public abstract SplineData.DataType Type { get; protected set; } ``` #### Property Value [SplineData](VM.Managed.DAFUL.SplineData.md).[DataType](VM.Managed.DAFUL.SplineData.DataType.md) ## Methods ### GetPoints() Gets the points. ```csharp public abstract IEnumerable GetPoints() ``` #### Returns [IEnumerable](https://learn.microsoft.com/dotnet/api/system.collections.generic.ienumerable-1)<[SplineData](VM.Managed.DAFUL.SplineData.md).[Point](VM.Managed.DAFUL.SplineData.Point.md)> The point list. ### GetPoints(string) Gets the points. ```csharp public abstract IEnumerable GetPoints(string documentFilePath) ``` #### Parameters `documentFilePath` [string](https://learn.microsoft.com/dotnet/api/system.string) The Document file path. #### Returns [IEnumerable](https://learn.microsoft.com/dotnet/api/system.collections.generic.ienumerable-1)<[SplineData](VM.Managed.DAFUL.SplineData.md).[Point](VM.Managed.DAFUL.SplineData.Point.md)> The point list. ### GetPoints(List<double>, List<double>) Gets the points. ```csharp public abstract void GetPoints(List lstX, List lstY) ``` #### Parameters `lstX` [List](https://learn.microsoft.com/dotnet/api/system.collections.generic.list-1)<[double](https://learn.microsoft.com/dotnet/api/system.double)> The LST X. `lstY` [List](https://learn.microsoft.com/dotnet/api/system.collections.generic.list-1)<[double](https://learn.microsoft.com/dotnet/api/system.double)> The LST Y. ### GetPoints(List<double>, List<double>, string) Gets the points. ```csharp public abstract void GetPoints(List lstX, List lstY, string strDocumentFilePath) ``` #### Parameters `lstX` [List](https://learn.microsoft.com/dotnet/api/system.collections.generic.list-1)<[double](https://learn.microsoft.com/dotnet/api/system.double)> The LST X. `lstY` [List](https://learn.microsoft.com/dotnet/api/system.collections.generic.list-1)<[double](https://learn.microsoft.com/dotnet/api/system.double)> The LST Y. `strDocumentFilePath` [string](https://learn.microsoft.com/dotnet/api/system.string) The Document file path. ### GetSchema() This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the to the class. ```csharp public virtual XmlSchema GetSchema() ``` #### Returns [XmlSchema](https://learn.microsoft.com/dotnet/api/system.xml.schema.xmlschema) An that describes the XML representation of the object that is produced by the method and consumed by the method. ### ReadXml(XmlReader) Generates an object from its XML representation. ```csharp public virtual void ReadXml(XmlReader reader) ``` #### Parameters `reader` [XmlReader](https://learn.microsoft.com/dotnet/api/system.xml.xmlreader) The stream from which the object is deserialized. ### WriteXml(XmlWriter) Converts an object into its XML representation. ```csharp public virtual void WriteXml(XmlWriter writer) ``` #### Parameters `writer` [XmlWriter](https://learn.microsoft.com/dotnet/api/system.xml.xmlwriter) The stream to which the object is serialized.
