javaee-HttpServletResponse 类相关源代码

ServletAPI?2.5的源代码

?

1.ServletResponse类的源代码如下：

?

package javax.servlet;import java.io.IOException;import java.io.PrintWriter;import java.util.Locale;public abstract interface ServletResponse{  public abstract String getCharacterEncoding();  public abstract String getContentType();  public abstract ServletOutputStream getOutputStream()    throws IOException;  public abstract PrintWriter getWriter()    throws IOException;  public abstract void setCharacterEncoding(String paramString);  public abstract void setContentLength(int paramInt);  public abstract void setContentType(String paramString);  public abstract void setBufferSize(int paramInt);  public abstract int getBufferSize();  public abstract void flushBuffer()    throws IOException;  public abstract void resetBuffer();  public abstract boolean isCommitted();  public abstract void reset();  public abstract void setLocale(Locale paramLocale);  public abstract Locale getLocale();}
