Syntax

public abstract class StyleInfoStore : IDisposable, ICloneable, IStyleInfo, IXmlSerializable

Remarks

You cannot instantiate a StyleInfoStore class directly. You have to derive a concrete class from this class that you can instantiate.

In derived classes of StyleInfoBase, you always need to implement a StyleInfoBase / StyleInfoStore pair. The StyleInfoStore holds all the data that are specific to the style object and should be persisted.

The StyleInfoBase is a wrapper around the StyleInfoStore. It provides type safe accessor properties to modify data of the underlying data store and can hold temporary information about the style object that does not need to be persisted.

In Essential Grid for example, the GridStyleInfo class holds extensive identity information about a style object such as cached base styles, row and column index, a reference to the grid model and more. These are all the information that can be discarded when the style is no longer used (because maybe the cell is not visible anymore). Only the StyleInfoStore part needs to be kept alive.

StyleInfoStore allows you to register any number of properties but keeps the data very memory efficient. Only properties that are actually used for a style object will be allocated for an object. The StyleObjectStore handles the storage of objects. For short integers, enums and Boolean values the data will be stored in a BitVector32 structure to save even more memory.

See the overview for StyleInfoBase for further discussion about style objects.

Constructors
