Method Details

parse

public static List<ParseResult> parse(String string,
 String textDelimiter,
 TextMatchingMode textMatchingMode)

parseExpression

public static ParseResult parseExpression(String string)

Parses the text entered in the filter row. The text is parsed to figure out the type of match operation (<, > etc.) and the value next to it.

Parameters:

string - entered by the user in the filter row text box

Returns:

the result of the parse operation

parseLiteral

public static ParseResult parseLiteral(String string)

setMatchOperation

public static <T> void setMatchOperation(ca.odell.glazedlists.matchers.ThresholdMatcherEditor<T,Object> thresholdMatcherEditor,
 ParseResult.MatchType matchType)

Set the Match operation on the ThresholdMatcherEditor corresponding to the ParseResult.MatchType. This must be done this way since ThresholdMatcherEditor.MatcherEditor is private.

Type Parameters:

T - type of the row object

Parameters:

thresholdMatcherEditor - The ThresholdMatcherEditor on which the match operation should be applied.

matchType - The match type to apply.

getSeparatorCharacters

public static String[] getSeparatorCharacters(String delimiter)

This method tries to extract the AND and the OR character that should be used as delimiter, so that a user is able to specify the operation for combined filter criteria. If it does not start with [ and ends with ] and does not match one of the following regular expressions, this method returns null which causes the default behavior, e.g. OR for String matchers, AND for threshold matchers.

• (.){2}
• (.)\\\\(.)
• \\\\(.){2}
• \\\\(.)\\\\(.)

Parameters:

delimiter - The delimiter that is configured via FilterRowConfigAttributes.TEXT_DELIMITER. Can be null.

Returns:

String array with the configured AND and the configured OR character, or null if the delimiter is not a two character regular expression. The first element in the array is the AND character, the second element is the OR character.
