Active Patterns

Active Pattern	Description
AndAlso : Expr -> (Expr * Expr) option	Recognizes expressions of the form a && b.
Applications : Expr -> (Expr * Expr list list) option	Recognizes expressions that represent the application of a (possibly curried or tupled) first class function value.
Bool : Expr -> bool option	Recognizes constant Boolean expressions.
Byte : Expr -> byte option	Recognizes constant byte expressions.
Char : Expr -> char option	Recognizes constant Unicode character expressions.
Double : Expr -> float option	Recognizes constant 64-bit floating point number expressions.
Int16 : Expr -> int16 option	Recognizes constant int16 expressions.
Int32 : Expr -> int32 option	Recognizes constant int32 expressions.
Int64 : Expr -> int64 option	Recognizes constant int64 expressions.
Lambdas : Expr -> (Var list list * Expr) option	Recognizes expressions that represent a (possibly curried or tupled) first class function value.
MethodWithReflectedDefinition : MethodBase -> Expr option	Recognizes methods that have an associated ReflectedDefinition.
OrElse : Expr -> (Expr * Expr) option	Recognizes expressions of the form a || b.
PropertyGetterWithReflectedDefinition : PropertyInfo -> Expr option	Recognizes property getters or values in modules that have an associated ReflectedDefinition.
PropertySetterWithReflectedDefinition : PropertyInfo -> Expr option	Recognizes property setters that have an associated ReflectedDefinition.
SByte : Expr -> sbyte option	Recognizes constant signed byte expressions.
Single : Expr -> single option	Recognizes constant 32-bit floating point number expressions.
SpecificCall : Expr -> Expr -> (Expr option * Type list * Expr list) option	A parameterized active pattern to recognize calls to a specified function or method. The returned elements are the optional target object (present if the target is an instance method), the generic type instantiation (non-empty if the target is a generic instantiation), and the arguments to the function or method.
String : Expr -> string option	Recognizes constant string expressions.
UInt16 : Expr -> uint16 option	Recognizes constant unsigned int16 expressions.
UInt32 : Expr -> uint32 option	Recognizes constant unsigned int32 expressions.
UInt64 : Expr -> uint64 option	Recognizes constant unsigned int64 expressions.
Unit : Expr -> unit option	Recognizes () constant expressions.
