public class ZipInputStream
extends InflaterInputStream
implements ZipConstants
This class implements an input stream filter for reading files in the ZIP file format. Includes support for both compressed and uncompressed entries.


Constructor Index

 o ZipInputStream(InputStream)
Creates a new ZIP input stream.

Method Index

 o close()
Closes the ZIP input stream.
 o closeEntry()
Closes the current ZIP entry and positions the stream for reading the next entry.
 o getNextEntry()
Reads the next ZIP file entry and positions stream at the beginning of the entry data.
 o read(byte[], int, int)
Reads from the current ZIP entry into an array of bytes.
 o skip(long)
Skips specified number of bytes in the current ZIP entry.

Constructors

 o ZipInputStream
    method ZipInputStream(in=InputStream) public 
Creates a new ZIP input stream.

Parameters:
in - the actual input stream

Methods

 o getNextEntry
    method getNextEntry() returns ZipEntry public     Signals IOException
Reads the next ZIP file entry and positions stream at the beginning of the entry data.

Throws: ZipException
if a ZIP file error has occurred
Throws: IOException
if an I/O error has occurred
 o closeEntry
    method closeEntry()  public     Signals IOException
Closes the current ZIP entry and positions the stream for reading the next entry.

Throws: ZipException
if a ZIP file error has occurred
Throws: IOException
if an I/O error has occurred
 o read
    method read(b=byte[], -
                off=int, -
                len=int) returns int public     Signals IOException
Reads from the current ZIP entry into an array of bytes. Blocks until some input is available.

Parameters:
b - the buffer into which the data is read
off - the start offset of the data
len - the maximum number of bytes read
Returns:
the actual number of bytes read, or -1 if the end of the entry is reached
Throws: ZipException
if a ZIP file error has occurred
Throws: IOException
if an I/O error has occurred
Overrides:
read in class InflaterInputStream
 o skip
    method skip(n=long) returns long public     Signals IOException
Skips specified number of bytes in the current ZIP entry.

Parameters:
n - the number of bytes to skip
Returns:
the actual number of bytes skipped
Throws: ZipException
if a ZIP file error has occurred
Throws: IOException
if an I/O error has occurred
Overrides:
skip in class InflaterInputStream
 o close
    method close()  public     Signals IOException
Closes the ZIP input stream.

Throws: IOException
if an I/O error has occurred
