Description = Generate list of 0x003C(IK key, Type valueType)0x003E together with value from value part.0x000D0x000A0x000D0x000AHas very few fail-scenarios (that is will almost always return TRUE).0x000D0x000ANote that the value itself will not be parsed (it is just returned in -Value- as a 'string?').0x000D0x000A0x000D0x000Athe valueType returned will always be an -IP- type.0x000D0x000A(but null for last key in hierarchy).0x000D0x000A0x000D0x000AThis is the first step in parsing a -PropertyStreamLine-, typically used by more higher level methods like0x000D0x000A-TryParseAndStore-,0x000D0x000A-TryParseDirectToIP-,0x000D0x000A-TryParseDirectToProperty-.0x000D0x000A0x000D0x000ANote that if the value part consists of individual items, like in -WholeCollection-, each of these has to be decoded individually again by the calling method (by calling -Decode-).0x000D0x000A0x000D0x000ADetails: For each key, decide which instance type of -IK- to use, that is, once of -PK-, -IKType-, -IKString- (or -IKLong- if an integer) in prioritized order).0x000D0x000A0x000D0x000AThe following priority is used for deciding -IK--keys:0x000D0x000A1) -PK- if a -PK- is recognized (like FirstName in 'Customer/42/FirstName:', based on a combination of found type 'Customer' and field 'FirstName')0x000D0x000A0x000D0x000A2) -IKType- if a -IP--derived type is recognized.0x000D0x000A(like 'Customer' in 'Customer/42/FirstName:')0x000D0x000A0x000D0x000A3) -IKString- for other cases (-IKLong- if an integer) .0x000D0x000A(like 42 in 'Custome/42/FirstName:'0x000D0x000A0x000D0x000AFor each key, decide what type of value-object to create if no object exists for that key (dedicated type like 'CustomerCollection' or 'Customer' if possible, if not -PRich-)0x000D0x000A0x000D0x000A        For 'Customer/42/FirstName = John', the tuple generated will look like this:0x000D0x000A        (which of the two alternative values are returned (IKType or IKString) depends on the actual type being known to the application (see -AllIPDerivedTypes-).0x000D0x000A        ---------------------------------------------------------------------------------------------------------0x000D0x000A                            key:                                                          valueType0x000D0x000A        Index 0 Customer    IKType(typeof(Customer)) / IKString('Customer')               CustomerCollection, alternatively PRich0x000D0x000A        Index 1 42          IKLong(42) (since integer, else IKString('42'))               Customer / PRich0x000D0x000A        Index 2 FirstName   PK (from CustomerP.FirstName) / IKString('FirstName')         Null.
