Java – regular expression types in eclipse mat

What type of regular expression syntax does mat support? I think it will be Java (although Java's regex itself is not conventional), but it doesn't seem to work I tried Perl's and it didn't work I need regex to filter the list in mat's histogram For example:

For arrays that just entered "[]" (without quotation marks), I can manually enter each array, but I want to complete the automation process at one time

Solution

Here is what can be used in @ L_ 419_ 2 @ mat histogram filter contains and excludes regular expressions of multiple strings

Regular expression filters include strings

Examples include "Java. Util", "Java. Lang", "char []"

Regular expression filter to exclude strings

Examples do not include "Java. Util", "char []"
