copyFile

public static void copyFile(java.lang.String filename1,
            java.lang.String filename2)
                     throws java.io.IOException

Copy filename1 into filename2 (mkdirs for filename2)

Parameters:

filename1 - the source file

filename2 - the target file

Throws:

java.io.IOException

Since:

jcms-5.0.5

copyFile

public static void copyFile(java.io.File f1,
            java.io.File f2)
                     throws java.io.IOException

Copy f1 into f2 (mkdirs for f2). This method is about 25% faster than IOUtil.copyFile()

Parameters:

f1 - the source file

f2 - the target file

Throws:

java.io.IOException

Since:

jcms-5.0.5

goToLine

public static boolean goToLine(java.nio.ByteBuffer buffer,
               long line)

Move the position of the given ByteBuffer to the given line.

Parameters:

buffer - the buffer to move the position.

line - the line to be reached

Returns:

true if the line has been reached, false otherwite (line out of buffer size)

Since:

jcms-5.0.0
