示例1: rollIfNeeded
import java.time.Instant; //导入方法依赖的package包/类
/**
* If necessary, close the current logfile and open a new one,
* updating {@link #writer}.
*/
private void rollIfNeeded() throws IOException {
// Do not roll unless record is complete, as indicated by flush
if (!flushed) return;
flushed = false;
// If we have not yet passed the roll over mark do nothing
Instant now = Instant.now();
if (now.isBefore(rollAt)) {
return;
}
// New file time, may not be the rollAt time if one or more intervals
// have passed without anything being written
Instant rollTime = now.truncatedTo(rollInterval);
// Determine the name of the file that will be written to
String name = this.baseName + format.format(LocalDateTime.ofInstant(rollTime, timeZone));
this.outPath = this.directory.resolve(name);
// Finish writing to previous log
if (writer != null) {
writer.flush();
writer.close();
}
// Ensure the parent directory always exists, even if it was removed out from under us.
// A no-op if the directory already exists.
Files.createDirectories(outPath.getParent());
// Create new file, set it as our write destination

// Point to the next time we want to roll the log, update rollAt
this.rollAt = rollTime.plus(1, rollInterval);
