| <pre>public abstract class <span class="typeNameLabel">JspWriter</span> |
| extends java.io.Writer</pre> |
| <div class="block"><p> |
| The actions and template data in a JSP page is written using the JspWriter object that is referenced by the implicit |
| variable out which is initialized automatically using methods in the PageContext object. |
| <p> |
| This abstract class emulates some of the functionality found in the java.io.BufferedWriter and java.io.PrintWriter |
| classes, however it differs in that it throws java.io.IOException from the print methods while PrintWriter does not. |
| <p> |
| <B>Buffering</B> |
| <p> |
| The initial JspWriter object is associated with the PrintWriter object of the ServletResponse in a way that depends |
| on whether the page is or is not buffered. If the page is not buffered, output written to this JspWriter object will |
| be written through to the PrintWriter directly, which will be created if necessary by invoking the getWriter() method |
| on the response object. But if the page is buffered, the PrintWriter object will not be created until the buffer is |
| flushed and operations like setContentType() are legal. Since this flexibility simplifies programming substantially, |
| buffering is the default for JSP pages. |
| <p> |
| Buffering raises the issue of what to do when the buffer is exceeded. Two approaches can be taken: |
| <ul> |
| <li>Exceeding the buffer is not a fatal error; when the buffer is exceeded, just flush the output. |
| <li>Exceeding the buffer is a fatal error; when the buffer is exceeded, raise an exception. |
| </ul> |
| <p> |
| Both approaches are valid, and thus both are supported in the JSP technology. The behavior of a page is controlled by |
| the autoFlush attribute, which defaults to true. In general, JSP pages that need to be sure that correct and complete |
| data has been sent to their client may want to set autoFlush to false, with a typical case being that where the |
| client is an application itself. On the other hand, JSP pages that send data that is meaningful even when partially |
| constructed may want to set autoFlush to true; such as when the data is sent for immediate display through a browser. |
| Each application will need to consider their specific needs. |
| <p> |
| An alternative considered was to make the buffer size unbounded; but, this had the disadvantage that runaway |
| computations would consume an unbounded amount of resources. |
| <p> |
| The "out" implicit variable of a JSP implementation class is of this type. If the page directive selects |
| autoflush="true" then all the I/O operations on this class shall automatically flush the contents of the buffer if an |
| overflow condition would result if the current operation were performed without a flush. If autoflush="false" then |
| all the I/O operations on this class shall throw an IOException if performing the current operation would result in a |
| buffer overflow condition.</div> |
