Class PageParser

java.lang.Object

fc.web.page.PageParser

public final class PageParser
extends Object

Parses a page and writes out the corresponding java file to the specified output. The parser and scanner is combined into one class here for simplicity (a seperate scanner is overkill for a simple LL(1) grammar such as molly pages).

Field Detail

d_mimetype

public static String d_mimetype

The name ("mimetype") of the[@ mimetype=....] directive. The value of none or an empty string will turn off writing any mimetype entirely (the user can then write a mimetype via the javax.servlet.ServletResponse.setContentType method manually).

Note, from ServletResponse

Note that the character encoding cannot be communicated via HTTP headers if the servlet
does not specify a content type; however, it is still used to encode text written via the
servlet response's writer.

d_encoding

public static String d_encoding
