REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
experiments, perform baseline and negative tests that provide experimental control, make sure
the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
Do not assume the numbers tell you what you want them to tell.

REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
experiments, perform baseline and negative tests that provide experimental control, make sure
the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
Do not assume the numbers tell you what you want them to tell.

REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
experiments, perform baseline and negative tests that provide experimental control, make sure
the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
Do not assume the numbers tell you what you want them to tell.

REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
experiments, perform baseline and negative tests that provide experimental control, make sure
the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
Do not assume the numbers tell you what you want them to tell.

REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
experiments, perform baseline and negative tests that provide experimental control, make sure
the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
Do not assume the numbers tell you what you want them to tell.

conclusion: 32 is near the limit point where things changed. for normal CharSequence (the classes we usually used, not some spacially made ones). when length <32, it usually be faster to use the original function, but for length > 32, it usually be faster to use .toString().toCharArray() directly.
Coverage increased (+0.0006%) to 94.958% when pulling 7be6c0b6e367cb3a96945c7bf8ea833178540ee3 on xenoamess-fork:refine_toCharArray into 5c7749d18f5b7f872cb5535969b1e0788eecdf22 on apache:master.
I sync'd this method's impl with the one in Commons Text; Text will eventually reuse this method. WRT this patch, I do not see any explanation for the use of the magic number 32.

@garydgregory Hi.
- I added a null-check for this function, so parameter null will not cause trouble now.( by StringUtils.length() function.)
- I added a length-check for not create new array when length == 0( by StringUtils.length() function too.)
I see your latest commit, and seems you are agreed with thest two changes.
Maybe I should tell more about how I get the number 32.
You can see in the jmh test I added, there actually exists two functions.
public static char[] toCharArrayOld(final CharSequence cs) {
if (cs instanceof String) {
return ((String) cs).toCharArray();
}
final int sz = cs.length();
final char[] array = new char[cs.length()];
for (int i = 0; i < sz; i++) {
array[i] = cs.charAt(i);
}
return array;
}
/**
* Green implementation of toCharArray.
*
* @param cs the {@code CharSequence} to be processed
* @return the resulting char array
* @since 3.11
*/
public static char[] toCharArrayNew(final CharSequence cs) {
return cs.toString().toCharArray();
}
They actually do the same thing, the only difference is speed. In theory, if the CharSequence is short enough, then toCharArrayOld should be faster, as it does not cast a toString. If CharSequence is long otherwise, then toCharArrayNew should be faster, as usually when we implement a CharSequence, in toString we can have some more efficient way than get all chars using index, one by one. In other world, there exist a magic number m, when length <= m, we should use toCharArrayOld. Otherwise we should use toCharArrayNew. And we get the function in the main codes, who use toCharArrayOld when length <= m, use toCharArrayNew when length > m
For why I chose the number 32: In short, that is gotten from performance tests in jmh. For CharBuffer and StringBuffer, it is always faster to use toCharArrayNew, means you can see n as -1. But for StringBuilder, it is around 32. At least 32 is better than 16, and the n is between 16 and 32 according to my jmh tests. I just think 32 is a elegant number to use here.
@garydgregory besides, I didn't see the meaning of reimplement this function in commons-text. I mean, commons-text have commons-lang as a dependency isn't it? shouldn't it be more reasonable to use the function in commons-lang directly?
We cannot release with a component with a snapshot dependency on another, so until Commons Lang is released, Commons Text can have it's own version of the method.

@garydgregory Oh yes you are right... I forgot we opened this function to public only recently...
@garydgregory so what is your opinions about this pr? And should I try to resolve conflict now?
