ZipInputStream JDK 1.6)

Methods

Hide/Show inherited methods

public int available () throws IOException [Overrides InflaterInputStream]

Returns 0 after EOF has reached for the current entry data, otherwise always return 1.

public void close () throws IOException [Overrides InflaterInputStream]

Closes this input stream and releases any system resources associated with the stream.

public void closeEntry () throws IOException

Closes the current ZIP entry and positions the stream for reading the next entry.

protected ZipEntry createZipEntry (String name)

Creates a new ZipEntry object for the specified entry name.

Creates a new ZipEntry object for the specified
entry name.
Returns: the ZipEntry just created
Parameters:
- name - the ZIP file entry name

protected void fill () throws IOException [Inherited From InflaterInputStream]

Fills input buffer with more data to decompress.

public ZipEntry getNextEntry () throws IOException

Reads the next ZIP file entry and positions the stream at the beginning of the entry data.

publicsynchronized void mark (int readlimit) [Inherited From InflaterInputStream]

Marks the current position in this input stream.

public boolean markSupported () [Inherited From InflaterInputStream]

Tests if this input stream supports the mark and reset methods.

Tests if this input stream supports the mark and
reset methods. The markSupported
method of InflaterInputStream returns
false.
Returns: a boolean indicating if this stream type supports the mark and reset methods.
See Also: InputStream.mark(int), InputStream.reset(),

public int read () throws IOException [Inherited From InflaterInputStream] [Specified in InputStream]

Reads a byte of uncompressed data.

public int read (byte[] b) throws IOException [Inherited From FilterInputStream]

Reads up to byte.length bytes of data from this input stream into an array of bytes.

Reads up to byte.length bytes of data from this input stream into an array of bytes. This method blocks until some input is available.

This method simply performs the call read(b, 0, b.length) and returns the result. It is important that it does not do in.read(b) instead; certain subclasses of FilterInputStream depend on the implementation strategy actually used.
Returns: the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.
Parameters:
- b - the buffer into which the data is read.
Throws:
- IOException - if an I/O error occurs.
See Also: FilterInputStream.read(byte[], int, int),

public int read (byte[] b, int off, int len) throws IOException [Overrides InflaterInputStream]

Reads from the current ZIP entry into an array of bytes.

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.
Returns: the actual number of bytes read, or -1 if the end of the entry is reached
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
Throws:
- NullPointerException - If b is null.
- IndexOutOfBoundsException - If off is negative, len is negative, or len is greater than b.length - off
- ZipException - if a ZIP file error has occurred
- IOException - if an I/O error has occurred

publicsynchronized void reset () throws IOException [Inherited From InflaterInputStream]

Repositions this stream to the position at the time the mark method was last called on this input stream.

The method reset for class InflaterInputStream does nothing except throw an IOException.
Throws:
- IOException - if this method is invoked.
See Also: InputStream.mark(int), IOException,

public long skip (long n) throws IOException [Overrides InflaterInputStream]

Skips specified number of bytes in the current ZIP entry.
