Clasa Java.util.zip.DeflaterOutputStream în Java
Clasa Java.util.zip.DeflaterInputStream în Java Această clasă implementează un filtru de flux de ieșire pentru comprimarea datelor în formatul de compresie „deflate”. De asemenea, este folosit ca bază pentru alte tipuri de filtre de compresie, cum ar fi GZIPOutputStream. Constructori și descriere
Syntax : public void close() throws IOException Overrides: close in class FilterOutputStream Throws: IOException
Syntax : protected void deflate() throws IOException Throws: IOException
Syntax : public void finish() throws IOException Throws: IOException
Syntax : public void flush() throws IOException Overrides: flush in class FilterOutputStream Throws: IOException
Syntax : public void write(byte[] b int off int len) throws IOException Overrides: write in class FilterOutputStream Parameters: b - the data to be written off - the start offset of the data len - the length of the data Throws: IOException
