Method Detail

evaluate

public static boolean evaluate(java.lang.String leftside,
                               java.lang.String rightside,
                               int operation,
                               boolean ignoreCase)

Evaluate the current operation.

Parameters:

leftside - String to be compared.

rightside - String or Regular expression.

operation - See the Operation subclass for values.

ignoreCase - Ignore the case of the values.

Returns:

result of operation

getPattern

private static org.apache.regexp.RE getPattern(java.lang.String pattern)

Get the regular expression implementing the pattern.

Parameters:

pattern - String representation of RE.

Returns:

RE Class representation of RE.

matchPattern

private static boolean matchPattern(java.lang.String componentAttribute,
                                    java.lang.String patternString)

This method is used to filter components' attributes based on a pattern specified by the user. For example, to search for all windows with title matching 'testWindow*'. Note: If the patternString is null, we need to avoid the PatternCompiler.compile() throwing a NullPointerException and in this case, return true if the componentAttribute is also null. The pattern syntax can be found at the Jakarta RegExp API Documentation in RE.

Parameters:

componentAttribute - The attribute text of the component to match against

patternString - The pattern to match with

Returns:

boolean whether the pattern is contained within the components' attribute text
