    NExpression Class
    In This Topic
    Represents an expression and serves as base class for all expressions. Expressions are used to automatically update the value of an element property.
    Object Model
    NExpression Class
    Public MustInherit Class NExpression 
       Implements INDomDeeplyCloneable, Nevron.Nov.Serialization.INDomCustomSerializable 
    Dim instance As NExpression
    The {element:property} value, which is updated is called "expression target" or simply "target". The expression is bound to target, if the TargetElement and TargetProperty properties are determined. The binding/unbinding is automatically performed when an expression is set to an element property via the SetFx methods of NElement. You can check whether the expression is bound to target via the IsBoundToTarget property.

    An expression can either be in parsed or unparsed state. The expression can be evaluated only when it is parsed. The parsing and evaluation are automatically performed.
