Type of Regex in Eclipse MAT

Question

What type of Regex syntax does MAT support? I assumed it would be Java's (though Java's Regex isnt Regular per se) but it didn't seem to work.. I tried Perl's and it didn't work. I need Regex's to filter out the list in MAT's Histogram. eg: Include arrays but exclude char arrays. Exclude java.lang.String Include java.util.Collections.*

For arrays just typing in "[]" (without quotes) works and I could manually type each one in but I'd like to do it in one go to automate the process.

Here's the Regex that you can use to include and exclude multiple Strings in the Eclipse MAT histogram filter.

Regex filter to include Strings

.*STRING1.*|.*STRING2.*|.*STRING3.*

Example include "java.util", "java.lang", "char[]"

.*java.util.*|.*java.lang.*|.*char\[\].*

Regex filter to exclude Strings

^(?!.*STRING1|.*STRING2|.*STRING3).*$

Example exclude "java.util", "java.lang", "char[]"

^(?!.*java.util|.*java.lang|.*char\[\]).*$
