TextFormattingRunProperties Class

Definition

Holds text formatting property information. This class derives from the abstract WPF TextRunProperties class.

Remarks

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

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

TextFormattingRunProperties may have empty properties. An empty property inherits the empty properties from some additional text. The TextFormattingRunProperties object can determine whether a property is empty or not: [PropertyName]Empty property. TextFormattingRunProperties

  also contains a facility for emptying a property: Clear[PropertyName]().

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