Java.util.zip.ZipInputStream class in Java
This class implements an input stream filter for reading files in the ZIP file format. Includes support for both compressed and uncompressed entries.
- ZipInputStream(InputStream in) : Creates a new ZIP input stream.
- ZipInputStream(InputStream in, Charset charset) : Creates a new ZIP input stream
- int available() : Returns 0 after EOF has reached for the current entry data, otherwise always return .
Programs should not count on this method to return the actual number of bytes
that could be read without blocking.
Syntax :public int available() throws IOException Overrides: available in class InflaterInputStream Returns: 1 before EOF and 0 after EOF has reached for current entry. Programs should not count on this method to return the actual number of bytes that could be read without blocking. Throws: IOException
- void close() : Closes this input stream and releases any system resources associated with the stream.
Syntax :public void close() throws IOException Overrides: close in class InflaterInputStream Throws: IOException
- void closeEntry() : Closes the current ZIP entry and positions the stream for reading the next entry.
Syntax :public void closeEntry() throws IOException Throws: ZipException IOException
- protected ZipEntry createZipEntry(String name) : Creates a new ZipEntry object for the specified entry name.
Syntax :protected ZipEntry createZipEntry(String name) Parameters: name - the ZIP file entry name Returns: the ZipEntry just created
- ZipEntry getNextEntry() : Reads the next ZIP file entry and positions the stream at the beginning of the entry data.
Syntax :public ZipEntry getNextEntry() throws IOException Returns: the next ZIP file entry, or null if there are no more entries Throws: ZipException IOException
- int read(byte b, int off, int len) : Reads from the current ZIP entry into an array of bytes. If len is not zero, the method blocks until some input is available; otherwise, no bytes are read and 0 is returned.
Syntax :public int read(byte b, int off, int len) throws IOException Parameters: b - the buffer into which the data is read off - the start offset in the destination array b 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: NullPointerException IndexOutOfBoundsException ZipException IOException
- long skip(long n) : Skips specified number of bytes in the current ZIP entry.
Syntax :public long skip(long n) throws IOException Parameters: n - the number of bytes to skip Returns: the actual number of bytes skipped Throws: ZipException IOException IllegalArgumentException
