public ListDataItem findClosestDataItem(ListDataItem[] dataList, java.lang.String name)
InsightInputFilter
ListDataItem
with display name, as returned by getName()
that is closest to the provided name. For example, suppose the user had the following items in the list:
If the passed in name is "equalsFoo()", the data item returned will be "equalsIgnoreCase()". If the passed in name is "regionMatches()", the data item returned will be "substring()".
This utility routine can be used by clients to help locate the closest data item that should be selected in an insight list so that the list tracks what the user is typing.

name
- the display name to find the closest data item forpublic ListDataItem[] getMatchingData(ListDataItem[] dataList, java.lang.String prefix)
Then there are 2 items which match the prefix "DM", and this routine will return an array of those 2 items. Note that uppercase items match lowercase prefixes. For example "dM" would return "DefaultMutableTreeNode" and "DesktopManager" and "jb" would return "JButton". However the reverse is not true and "EQ" would not return "equalsIgnoreCase".
Note that if the prefix is an empty string, "", then all items will be returned. If there are no items that start with the specified prefix, an empty array will be returned.

ListDataItems
the data list that begin with the specified name. As with findClosestDataItem()
, the name of the ListDataItem
used is what is returned by getName()
.
Note that a case-insensitive comparison is used for determining the common prefix but the prefix's casing is preserved. So for example, if the specified name is "eq", and the following data items are in the list:
Then the common prefix is "equals", and since the first data item is "EQUALS_SOMETHING", the common prefix returned will be "eqUALS".
If there are no items that start with the specified name, an empty (zero-length) String will be returned.
