CpioArchiveInputStream(InputStream in)
Construct the cpio input stream with a blocksize of
BLOCK_SIZE and expecting ASCII file
names. |
CpioArchiveInputStream(InputStream in,
int blockSize)
Construct the cpio input stream with a blocksize of
BLOCK_SIZE expecting ASCII file
names. |
CpioArchiveInputStream(InputStream in,
int blockSize,
String encoding)
Construct the cpio input stream with a blocksize of
BLOCK_SIZE. |
CpioArchiveInputStream(InputStream in,
String encoding)
Construct the cpio input stream with a blocksize of
BLOCK_SIZE. |
| Modifier and Type | Method and Description |
|---|---|
int |
available()
Returns 0 after EOF has reached for the current entry data, otherwise
always return 1.
|
void |
close()
Closes the CPIO input stream.
|
CpioArchiveEntry |
getNextCPIOEntry()
Reads the next CPIO file entry and positions stream at the beginning of
the entry data.
|
ArchiveEntry |
getNextEntry()
Returns the next Archive Entry in this Stream.
|
static boolean |
matches(byte[] signature,
int length)
Checks if the signature matches one of the following magic values:
Strings:
"070701" - MAGIC_NEW
"070702" - MAGIC_NEW_CRC
"070707" - MAGIC_OLD_ASCII
Octal Binary value:
070707 - MAGIC_OLD_BINARY (held as a short) = 0x71C7 or 0xC771
|
int |
read(byte[] b,
int off,
int len)
Reads from the current CPIO entry into an array of bytes.
|
long |
skip(long n)
Skips specified number of bytes in the current CPIO entry.
