getCharset

Method Detail

getLevel

int getLevel()

Returns the compression level for entries. This property is only used if the effective compression method is ZipEntry.DEFLATED or ZipEntry.BZIP2. Legal values are Deflater.DEFAULT_COMPRESSION or range from Deflater#BEST_SPEED to Deflater#BEST_COMPRESSION.

Returns:

The compression level for entries.

getMethod

int getMethod()

Returns the default compression method for entries. This property is only used if a ZipEntry does not specify a compression method. Legal values are ZipEntry.STORED, ZipEntry.DEFLATED and ZipEntry.BZIP2.

Returns:

The default compression method for entries.

ZipEntry.getMethod()

getOverheadSize

int getOverheadSize()

Returns the number of entries which can be additionally accomodated by the internal hash map without resizing it. When a new ZIP file is created, this constant is used in order to compute the initial capacity of the internal hash map. When an existing ZIP file is appended to, this constant is added to the number of entries in order to compute the initial capacity of the internal hash map.

Returns:

The number of entries which can be additionally accomodated by the internal hash map without resizing it.
