FSharpValue.PreComputeRecordConstructor(recordType, ?allowAccessToPrivateRepresentation)
Parameters:
Type
-
The type of record to construct.
?allowAccessToPrivateRepresentation : bool
-
Optional flag that denotes accessibility of the private representation.

Full Usage:
FSharpValue.PreComputeRecordConstructorInfo(recordType, ?allowAccessToPrivateRepresentation)
Parameters:
Type
-
The record type.
?allowAccessToPrivateRepresentation : bool
-
Optional flag that denotes accessibility of the private representation.

Full Usage:
FSharpValue.PreComputeRecordReader(recordType, ?allowAccessToPrivateRepresentation)
Parameters:
Type
-
The type of record to read.
?allowAccessToPrivateRepresentation : bool
-
Optional flag that denotes accessibility of the private representation.
Returns: obj -> objnull array
An optimized reader for the given record type.
|
Precompute a function for reading all the fields from a record. The fields are returned in the same order as the fields reported by a call to Microsoft.FSharp.Reflection.Type.GetInfo for this type. Assumes the given type is a RecordType. If not, ArgumentException is raised during pre-computation. Using the computed function will typically be faster than executing a corresponding call to Value.GetInfo because the path executed by the computed function is optimized given the knowledge that it will be used to read values of the given type.

FSharpValue.PreComputeUnionTagReader(unionType, ?allowAccessToPrivateRepresentation)
Parameters:
Type
-
The type of union to optimize reading.
?allowAccessToPrivateRepresentation : bool
