SGLLesserThan provides an ascending comparator struct for use with SGEXTN Containers, this should be used most of the time when using SGLPriorityQueue, SGLSet, SGLMultiSet, or SGLMap. You need operator‹ defined to use SGLLesserThan with custom structs. SGLLesserThan works with any object pointers. This is a template based class with no separate source file.
SGLLesserThan calls operator‹ on the corresponding data type if it is a custom struct. For object pointers, direct comparison is undefined behaviour if they are not allocated in the same C array creation call, so SGLLesserThan converts them to bytes first and compares the bytes.
Returns if a is lesser than b.
"lesser than" is Singlish. SGEXTN API names can use any word understood by most people in Singapore, so Singlish also can one.
This is internally used by SGLPriorityQueue, SGLSet, SGLMultiSet, and SGLMap when SGLLesserThan is selected as the comparator struct.
The presense of operator() makes SGLLesserThan a functor.
This will not compile if operator‹ is not defined for T. Check the source code of any SGEXTN struct (SGXChar, SGXString, SGXColourRGBA, SGXColourHSLA, SGXIdentifier, SGXTimeStamp, SGXVector2) to see how to define operator‹.
