Examples with FileMatchInfo com.axway.ats.common.filesystem.FileMatchInfo used on opensource projects

Example 1 with FileMatchInfo

use of com.axway.ats.common.filesystem.FileMatchInfo in project ats-framework by Axway.

the class FileSystemOperations method findNewTextInFile.

/**
     * Searches some texts in file and it remembers where the search stopped.
     * The following search starts from the point where the last search stopped<br/>
     *
     * This method is appropriate for growing text files(for example some kind of a log file)
     *
     * @param filePath the file to work with
     * @param searchTexts the texts to search for. At least one should match.
     * @param isRegex if the searchText is regular expression, otherwise the text must
     * simply be contained by the file line
     * @return {@link FileMatchInfo} object
