Remarks

This class is used to hold all information about the text formatting properties. Once created, it is immutable, and all modifications of the object return different objects. For each unique set of TextFormattingRunProperties there exists exactly one object. If a TextFormattingRunProperties has reference equality to another, their properties are identical. Conversely, if a TextFormattingRunProperties object has reference inequality, their properties are different.

Checking reference equality is the only way to determine whether two TextFormattingRunProperties are different. Checking the equality of each property of the object may indicate the two are identical, but that may or may not be the case.

A TextFormattingRunProperties instance may have empty properties. An empty property inherits the empty properties from some additional text. TextFormattingRunProperties has methods that determine whether a property is empty or not (PropertyNameEmpty) and that empty a property (PropertyNameClear).

All freezable fields of the TextFormattingRunProperties object are frozen on creation.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
