do we need to Cache expression compile target?

Hi JSLT Team，

for the title, do we need to Cache expression compile target?

actually, my project's jstl script is configed statically not dynamic, and some script is long, if cache this compile target maybe useful?

some project have Cache compilation, such as mybatis will save sql tree nodes in memory, is jstl also support?

I'm not sure I understand the question, but if you want to avoid compiling the template over and over again, you can simply store the Expression object and reuse it. Then you parse once, and use the JSLT expression many times.

yes, what you said is somthing that i'm going to do, i just want to confirm whether compile() would cache my template :)

Well, it's not going to cache the template string. But the same Expression object can be used many times with different input.
