Razred Java.util.zip.DeflaterInputStream v Javi Ta razred izvaja filter izhodnega toka za stiskanje podatkov v formatu stiskanja 'deflate'. Uporablja se tudi kot osnova za druge vrste kompresijskih filtrov, kot je GZIPOutputStream. Konstruktorji in opis
DeflaterOutputStream(OutputStream out) :
Ustvari nov izhodni tok s privzetim kompresorjem in velikostjo medpomnilnika.
DeflaterOutputStream(OutputStream out boolean syncFlush) :
Ustvari nov izhodni tok s privzetim kompresorjem, privzeto velikostjo medpomnilnika in podanim načinom izpiranja.
DeflaterOutputStream(OutputStream iz Deflater def) :
Ustvari nov izhodni tok s podanim kompresorjem in privzeto velikostjo medpomnilnika.
DeflaterOutputStream(OutputStream out Deflater def boolean syncFlush) :
Ustvari nov izhodni tok s podanim načinom izpiranja kompresorja in privzeto velikostjo medpomnilnika.
DeflaterOutputStream(OutputStream out Deflater def int size):
Ustvari nov izhodni tok s podanim kompresorjem in velikostjo medpomnilnika.
DeflaterOutputStream(OutputStream out Deflater def int size boolean syncFlush) :
Ustvari nov izhodni tok z določeno velikostjo medpomnilnika kompresorja in načinom izpiranja. Metode:
void close():
Writes remaining compressed data to the output stream and closes the underlying stream.
Syntax : public void close() throws IOException Overrides: close in class FilterOutputStream Throws: IOException
zaščiten void deflate():
Writes next block of compressed data to the output stream.
Finishes writing compressed data to the output stream without closing the underlying stream.
Syntax : public void finish() throws IOException Throws: IOException
void flush():
Flushes the compressed output stream.
Syntax : public void flush() throws IOException Overrides: flush in class FilterOutputStream Throws: IOException
void write(byte[] b int off int len) :
Writes an array of bytes to the compressed output stream.
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
void write(int b):
Writes a byte to the compressed output stream.
Syntax : public void write(int b) throws IOException Overrides: write in class FilterOutputStream Parameters: b - the byte to be written Throws: IOException
