public static final int STORED

Compression method for uncompressed entries.

public static final int DEFLATED

Compression method for compressed (deflated) entries.

public ZipEntry(String name)

Creates a new ZIP file entry with the specified name.

Parameters:

name - the entry name

Throws: NullPointerException

if the entry name is null

Throws: IllegalArgumentException

if the entry name is longer than 0xFFFF bytes

public String getName()

Returns the name of the entry.

public void setTime(long time)

Sets the modification time of the entry.

Parameters:

time - the entry modification time in number of milliseconds since the epoch

public long getTime()

Returns the modification time of the entry, or -1 if not specified.

public void setSize(long size)

Sets the uncompressed size of the entry data.

Parameters:

size - the uncompressed size in bytes

Throws: IllegalArgumentException

if the specified size is less than 0 or greater than 0xFFFFFFFF bytes

public long getSize()

Returns the uncompressed size of the entry data, or -1 if not known.

public void setCrc(long crc)

Sets the CRC-32 checksum of the uncompressed entry data.

Parameters:

crc - the CRC-32 value

Throws: IllegalArgumentException

if the specified CRC-32 value is less than 0 or greater than 0xFFFFFFFF

public long getCrc()

Returns the CRC-32 checksum of the uncompressed entry data, or -1 if not known.

public void setMethod(int method)

Sets the compression method for the entry.

Parameters:

method - the compression method, either STORED or DEFLATED

Throws: IllegalArgumentException

if the specified compression method is invalid

public int getMethod()

Returns the compression method of the entry, or -1 if not specified.

public void setExtra(byte extra[])

Sets the optional extra field data for the entry.

Parameters:

extra - the extra field data bytes

Throws: IllegalArgumentException

if the length of the specified extra field data is greater than 0xFFFFF bytes

public byte[] getExtra()

Returns the extra field data for the entry, or null if none.

public void setComment(String comment)

Sets the optional comment string for the entry.

Parameters:

comment - the comment string

if the length of the specified comment string is greater than 0xFFFF bytes

public String getComment()

Returns the comment string for the entry, or null if none.

public long getCompressedSize()

Returns the compressed size of the entry data, or -1 if not known. In the case of a stored entry, the compressed size will be the same as the uncompressed size of the entry.

public boolean isDirectory()

Returns true if this is a directory entry. A directory entry is defined to be one whose name ends with a '/'.

public String toString()

Returns a string representation of the ZIP entry.

Overrides:
