Open Type

This dialog allows you to browse the workbench for a type to open in an editor or type hierarchy

  • Enter type name prefix or pattern: In this field, type the first few characters of the type you want to select.

    The following pattern kinds are supported:

    • "*" for any string and "?" for any character
    • terminating "<" or " " (space) to prevent the automatic prefix matching, e.g. "java.*Access<" to match java.util.RandomAccess but not
    Camel case:
    • "TZ" for types containing "T" and "Z" as upper-case letters in camel-case notation, e.g. java.util.TimeZone
    • "NuPoEx" or "NuPo" for types containing "Nu", "Po", (and "Ex") as parts in camel-case notation, e.g. java.lang.NullPointerException
    • terminating "<" or " " (space) to fix the number of camel-case parts, e.g. "HMap<" and "HaMap<" match "HashMap" and "HatMapper", but not "HashMapEntry" nor "Hashmap".

    Both pattern kinds also support package prefixes, e.g. "j.util.*Map<".

  • Matching items: This list displays matches for the pattern you type in the Enter type name prefix or pattern field. Recently opened types show up in a history section at the top of the list.
