PersistShow2

The UnShow type class instance for type A1.

The UnShow type class instance for type A2.

Finds value of this UnShow type, returns error if more than one match.

Tries to return a value of the type from an RSON expression Expr that has been parsed from a String or text file. This method must be implemented by all instances.

Tries to construct the type from a sequence of parameters using out of order named parameters and default values.

Trys to build an object of type T from the statement.

Finds a setting with a key / code of type KT and a value of the type of this UnShow instance from a [Statement].

Finds a key setting with Key type KT of the type of this UnShow instance from an Arr[Statement].

1st parameter name.

2nd parameter name.

Number of parameter constituents of this class.

The optional default value for parameter 1.

The optional default value for parameter 2.

Sequence of the names of parameter constituents of this class.

Finds an identifier setting with a value type of this UnShow instance from an Arr[Statement].

Finds an identifier setting with a value of the type of this UnShow instance from a [Statement].

Provides the standard string representation for the object. Its called ShowT to indicate this is a type class method that acts upon an object rather than a method on the object being shown.

Simple values such as Int, String, Double have a syntax depth of one. A Tuple3[String, Int, Double] has a depth of 2. Not clear whether this should always be determined at compile time or if sometimes it should be determined at runtime.

The RSON type of T. This the only data that a ShowT instance requires, that can't be implemented through delegation to an object of type Show.

Produces an ArrImut of the UnShow type from Statements (Refs[Statement].
