This is the SMPL playground, a repository that contains the development efforts and proof of concept for the SMPL framework and suite of components.
The logic component provides a number of utilities for creating functional logic within an application, such as:
Comparators are classes that take two values of a given type and compare them to determine their equality, as well as a sorting order. These classes perform an operation analogous to a mathematical sign function, returning a number less than 0 if the A is less than B, 0 if A is equal to B, and a number greater than 0 if A is greater than B. Comparators are of primary use in the sorting of values.
Tip
Comparators are binary operations with the signature <mixed, mixed, int>, so they can be passed where binary operations are accepted.
Consumers are classes that take a value of a given type and "consume" it. What this essentially means is that it does something with it, and does not return a value.
Operations are class representations of encapsulated logic that is performed on a value of a given type, and returns a value of another type.
Binary operations are an alternative operation that instead takes two arguments and returns a value.
Tip
Binary operations are not normal operations so can't be passed where operations are accepted.
Unary operations are more specific operations that both takes an argument and returns a value of the same type.
Tip
Unary operations are also normal operations so can be passed where operations are accepted.
Predicates are class representations of boolean-value functions, taking a single argument of a given type, and returning true or false dependent on its particular implementation. Predicates are of primary use in the filtering of values.
Tip
Predicates are operations with the signature <mixed, bool>, so they can be passed where operations are accepted.
Suppliers are the opposite of consumers, taking no arguments and returning a value of a given type.
The Optional class either contains a value or not, with the value sometimes being empty.
This class gives you more control over a value,
providing a few methods for retrieving a default value if none is present.
You'd use an optional instance if you wanted to provide a fluid interface to the presence of a value.
The collections component provides collections.
