[MDAPI-80] [C++][IPF] Implement custom fields in InstrumentProfile #52

Closed AnatolyKalin closed 4 months ago

AnatolyKalin commented 4 months ago

It is required to refactor InstrumenProfile to allow custom fields to be retrieved from it.

What must be done:

The API should be migrated to Graal SDK v1.1.22+
InstrumentProfile should be represented as a JavaObjectHandle<InstrumentProfile>.
All methods that accept/return this class must return its handle.
All methods in InstrumentProfile should be referred to IsolatedInstrumentProfile.

ttldtor commented 4 months ago

The API was migrated to Graal SDK v1.1.22
Added methods:
- InstrumentProfile::getField
- InstrumentProfile::setField
- InstrumentProfile::getNumericField
- InstrumentProfile::setNumericField
- InstrumentProfile::getDateField
- InstrumentProfile::setDateField
- InstrumentProfile::getNonEmptyCustomFieldNames
[BREAKING]: All toString methods can now throw exceptions.
