Class FileMode

java.lang.Object

io.tesla.proviso.archive.FileMode

public abstract class FileMode
extends Object

Constants describing various file modes recognized by GIT.

GIT uses a subset of the available UNIX file permission bits. The FileMode class provides access to constants defining the modes actually used by GIT.

public static final FileMode REGULAR_FILE

Mode indicating an entry is a non-executable file.

EXECUTABLE_FILE

public static final FileMode EXECUTABLE_FILE

Mode indicating an entry is an executable file.

Method Detail

fromBits

public static final FileMode fromBits(int bits)

Convert a set of mode bits into a FileMode enumerated value.

Parameters:

bits - the mode bits the caller has somehow obtained.

Returns:

the FileMode instance that represents the given bits.

equals

public abstract boolean equals(int modebits)

Test a file mode for equality with this FileMode object.

Parameters:

modebits -

Returns:

true if the mode bits represent the same mode as this object

copyTo

public void copyTo(OutputStream os)
            throws IOException

Copy this mode as a sequence of octal US-ASCII bytes.

The mode is copied as a sequence of octal digits using the US-ASCII character encoding. The sequence does not use a leading '0' prefix to indicate octal notation. This method is suitable for generation of a mode string within a GIT tree object.

Parameters:

os - stream to copy the mode to.

Throws:

IOException - the stream encountered an error during the copy.

copyTo

public void copyTo(byte[] buf,
          int ptr)

Copy this mode as a sequence of octal US-ASCII bytes. The mode is copied as a sequence of octal digits using the US-ASCII character encoding. The sequence does not use a leading '0' prefix to indicate octal notation. This method is suitable for generation of a mode string within a GIT tree object.

Parameters:

buf - buffer to copy the mode to.

ptr - position within buf for first digit.

copyToLength

public int copyToLength()

Returns:

the number of bytes written by copyTo(OutputStream).

toString

public String toString()

Format this mode as an octal string (for debugging only).

Overrides:

toString in class Object

getBits

public int getBits()

Returns:

The mode bits as an integer.

makeExecutable

public static int makeExecutable(int fileMode)

getFileMode

public static int getFileMode(File file)

toPermissionsSet

public static Set<PosixFilePermission> toPermissionsSet(int mode)

toUnix

public static String toUnix(int mode)
