Constructor Detail

XecureOutputStream

public XecureOutputStream(XecureSession xecureSession,
                          javax.servlet.ServletOutputStream out,
                          int buffer_size)

Method Detail

close

public void close()
           throws java.io.IOException
servlet버전에서는 항상 끝에서 불렀다. 하지만 jsp 에서는 기본적으로 불리지 않는다. 그러므로 명시적으로 호출하지 않으면 사용되지 않는다.

Throws:
java.io.IOException

flush

public void flush()
           throws java.io.IOException
기본적으로 파일의 끝에서 불려진다. 즉 close()를 대신하게 된다. 하지만 jsp 에서는 기본적으로.jsp 파일의 끝에서 불린다. BEGIN_ENC 와 매칭되는 END_ENC 가 없을 때 현재는 BEGIN_ENC 다음의 내용은 화면에 출력되지 않는다. 만약 오류 메시지를 내고 싶다면 여기서 처리하면 된다.

Throws:
java.io.IOException

write

public void write(byte[] buf,
                  int off,
                  int len)
           throws java.io.IOException
기본 출력함수

Parameters:
buf - character buffer array
off - offset
len - 출력할 데이타 길이
Throws:
java.io.IOException

write

public void write(int c)
           throws java.io.IOException
Write a single character.

Throws:
java.io.IOException

write

public void write(byte[] buf)
