Specified by:

clear in class javax.servlet.jsp.JspWriter

Throws:

clearBuffer

public void clearBuffer()
                 throws java.io.IOException

Description copied from class: javax.servlet.jsp.JspWriter

Clears the current contents of the buffer. Unlike clear(), this method will not throw an IOException if the buffer has already been flushed. It merely clears the current content of the buffer and returns.

This method needs not be invoked explicitly for the initial JspWriter as the code generated by the JSP container will automatically include a call to close().

Closing a previously-closed stream, unlike flush(), has no effect.

Specified by:

close in interface java.io.Closeable

Specified by:

close in class javax.servlet.jsp.JspWriter

Throws:

java.io.IOException - If an I/O error occurs

getRemaining

public int getRemaining()

getReader in class javax.servlet.jsp.tagext.BodyContent

Returns:

the value of this BodyContent as a Reader

getString

public java.lang.String getString()

Description copied from class: javax.servlet.jsp.tagext.BodyContent

Return the value of the BodyContent as a String.

Specified by:

getString in class javax.servlet.jsp.tagext.BodyContent

Returns:

the value of the BodyContent as a String

Specified by:

writeOut in class javax.servlet.jsp.tagext.BodyContent

Parameters:

writer - The writer into which to place the contents of this body evaluation

Throws:

java.io.IOException - if an I/O error occurred while writing the contents of this BodyContent to the given Writer

Description copied from class: javax.servlet.jsp.JspWriter

This method returns the size of the buffer used by the JspWriter.

Overrides:

getBufferSize in class javax.servlet.jsp.JspWriter

Returns:

the size of the buffer in bytes, or 0 is unbuffered.
