Methods

	Name	Description
	ApplyDefaults(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will update an instance of type T applying any specified DefaultValueAttribute or DefaultValueExpressionAttribute instances that are declared on the type T properties. Target T instance is accepted as the parameter to the returned delegate ActionT.
	ApplyDefaultsTExpressionScope(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will update an instance of type T accepting a contextual IValueExpressionScopeT object parameter applying any specified DefaultValueAttribute or DefaultValueExpressionAttribute instances that are declared on the type T properties. Target T instance needs to be assigned to the Instance property prior to call.
	ApplyDefaultsForTypeTValueExpressionAttribute(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will update an instance of type T applying any specified DefaultValueAttribute or TValueExpressionAttribute instances that are declared on the type T properties. Target T instance is accepted as the parameter to the returned delegate ActionT.
	ApplyDefaultsForTypeTValueExpressionAttribute, TExpressionScope(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will update an instance of type T accepting a contextual IValueExpressionScopeT object parameter applying any specified DefaultValueAttribute or TValueExpressionAttribute instances that are declared on the type T properties. Target T instance needs to be assigned to the Instance property prior to call.
	BuildTree	(Inherited from ExpressionCompiler)
	Call	(Inherited from CompiledExpressionT)
	ClearCompiledMethod	(Inherited from CompiledExpressionT)
	Compile	(Inherited from CompiledExpressionT)
	Compile``1(String)	(Inherited from ExpressionCompiler)
	CompileCall	(Inherited from CompiledExpressionT)
	CreateInstance(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will create new instance of type T applying any specified DefaultValueAttribute or DefaultValueExpressionAttribute instances that are declared on the type T properties.
	CreateInstanceTExpressionScope(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will create new instance of type T accepting a contextual IValueExpressionScopeT object parameter applying any specified DefaultValueAttribute or DefaultValueExpressionAttribute instances that are declared on the type T properties.
	CreateInstanceForTypeTValueExpressionAttribute(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will create new instance of type T applying any specified DefaultValueAttribute or TValueExpressionAttribute instances that are declared on the type T properties.
	CreateInstanceForTypeTValueExpressionAttribute, TExpressionScope(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will create new instance of type T accepting a contextual IValueExpressionScopeT object parameter applying any specified DefaultValueAttribute or TValueExpressionAttribute instances that are declared on the type T properties.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	Eval	(Inherited from CompiledExpressionT)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GenerateLambda``2	(Inherited from CompiledExpressionT)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	InitializeType	Validates that any static type T functionality is initialized.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	Parse	Parses the expression with the provided parameter expression scope and optional typeRegistry.
	ScopeCompile	(Inherited from CompiledExpressionT)
	ScopeCompileCall	(Inherited from CompiledExpressionT)
	ScopeParse	(Inherited from ExpressionCompiler)
	ToString	(Inherited from ExpressionCompiler)
	UpdateExpressions(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will execute expression assignments on an instance of type T where expressions are TypeConvertedValueExpressionAttribute instances that are declared on the type T properties. Target T instance is accepted as the parameter to the returned delegate ActionT.
	UpdateExpressionsTExpressionScope(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will execute expression assignments on an instance of type T accepting a contextual IValueExpressionScopeT object parameter where expressions are TypeConvertedValueExpressionAttribute instances that are declared on the type T properties. Target T instance needs to be assigned to the Instance property prior to call.
	UpdateExpressionsForTypeTValueExpressionAttribute(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will execute expression assignments on an instance of type T where expressions are TValueExpressionAttribute instances that are declared on the type T properties. Target T instance is accepted as the parameter to the returned delegate ActionT.
	UpdateExpressionsForTypeTValueExpressionAttribute, TExpressionScope(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will execute expression assignments on an instance of type T accepting a contextual IValueExpressionScopeT object parameter where expressions are TValueExpressionAttribute instances that are declared on the type T properties. Target T instance needs to be assigned to the Instance property prior to call.
	UpdateInstance(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will update an instance of type T applying any specified UpdateValueExpressionAttribute instances that are declared on the type T properties. Target T instance is accepted as the parameter to the returned delegate ActionT.

Target T instance is accepted as the parameter to the returned delegate ActionT.
	UpdateInstanceForTypeTValueExpressionAttribute, TExpressionScope(IEnumerablePropertyInfo, TypeRegistry)	Generates a delegate that will update an instance of type T accepting a contextual IValueExpressionScopeT object parameter applying any specified TValueExpressionAttribute instances that are declared on the type T properties. Target T instance needs to be assigned to the Instance property prior to call.
	UpdateProperties	Generates a delegate that will update an instance of type T assigning values from TypeConvertedValueExpressionAttribute instances that are declared on the type T properties to the property values. Target T instance is accepted as the parameter to the returned delegate ActionT.
