The keys are typically strings. A common programmer mistake is to write out these string keys literally every time a key is used; if you then misspell a key name, there’s no penalty at compile time, but your code will mysteriously fail to work correctly. The proper approach is to ...

As I mentioned in Chapter 1, Swift object types come in three flavors: enum, struct, and class. What are the differences between them? And how would you create your own object type? That’s what this chapter is about. I’ll describe object types in general, and then each of the ...
Supports: • Most of the IDL data types • Specification of additional DDS-specific concepts, such as keys • Single Inheritance • Type versioning and evolution • Sparse types (types, the samples of which may omit values for certain fields; see below for a formal treatment) Several ...
Our tuples differ in that they have keys, similar to primary keys in a row of a relational database, and relation types implicitly define a map from keys to non-keys. A relation type does not contain two tuples with equal keys but different non-key parts. Some languages integrate object...
The standards that I provided earlier (from the UK) might be reasonable assumptions that I am sure plenty of work was put into to formulate. It's better to likely err on the side of caution and be able to handle values that might come in (even though they may be anomalies). You can...
In the U.S. most states require that an "alternative septic system" be designed by a professional and submitted to the local health department for approval. Examples of advanced septic designs include aerobic septic systems, chemical, composting, incinerating & waterless toilets, evaporation-...
