Java의 Java.util.zip.DeflaterOutputStream 클래스
Java의 Java.util.zip.DeflaterInputStream 클래스 이 클래스는 'deflate' 압축 형식으로 데이터를 압축하기 위한 출력 스트림 필터를 구현합니다. 또한 GZIPOutputStream과 같은 다른 유형의 압축 필터의 기초로도 사용됩니다. 생성자 및 설명
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
Syntax : public void write(int b) throws IOException Overrides: write in class FilterOutputStream Parameters: b - the byte to be written Throws: IOExceptionJava
