BaseType * dap_html_form::basetype_to_wwwtype ( BaseType * bt )

Given a BaseType variable, return a pointer to a new variable that has the same parent types (Byte, et c.) but is now one of the WWW specializations.

Parameters

bt	A BaseType such as NCArray, HDFArray, ...

Returns: A BaseType that uses the WWW specialization (e.g., WWWArray).

DDS * dap_html_form::dds_to_www_dds ( DDS * dds )

Given a DDS filled with variables that are one specialization of BaseType, build a second DDS which contains variables made using the WWW specialization.

Parameters

dds A DDS

Returns: A DDS where each variable in dds is now a WWW* variable.

string dap_html_form::fancy_typename ( BaseType * v )

Return a string which describes the datatype of a DODS variable.

Parameters

v	The variable.

Returns: A string describing the variable's type.

string dap_html_form::get_fqn ( BaseType * var )

Get the Fully Qualified Name for a variable.

This function uses the BaseType name() and get_parent() methods to 'walk up' the hierarchy and build the FQN for a given variable.

Returns: The FQN for a variable

Parameters

var	The variable.

string dap_html_form::name_for_js_code ( const string & dods_name )

Generate variable names to be used by the JavaScript code.

These names must not interfere with JavaScript itself, which seems to have an always expanding set of reserved words. Maybe that's stopped now (1/25/2001 jhrg) but the set is large and includes words such as `Location' which is also a dataset variable name. By making the JS variable names `dods_' the HTML/JS page/code is still readable without stepping on JS' reserved words.

Note that this is a function and not a class member; I included it in the WWWOutput class since it seems to fit here.

Parameters

dods_name A string that contains the name of a variable.

Returns
A name suitable for use in JavaScript code similar to the #dods_name# parameter.

void dap_html_form::write_html_form_interface	(	ostream &	strm,

		bool	html_header,
		bool	netcdf3_file_response,
		bool	netcdf4_file_response,
		const string &	admin_name,
		const string &	help_location
	)

Using the stuff in WWWOutput and the hacked (specialized) print_val() methods in the WWW* classes, write out the HTML form interface.

Todo:: Modify this code to expect a DDS whose BaseTypes are loaded with Attribute tables.

Parameters

dest	Write HTML here.
dds	A DataDDS loaded with data; the BaseTypes in this must be WWW* instances,
url	The URL that should be initially displayed in the form. The form's javascript code will update this incrementally as the user builds a constraint.
html_header	Print a HTML header/footer for the page. True by default.
admin_name	"support@opendap.org" by default; use this as the address for support printed on the form.
help_location	"http://www.opendap.org/online_help_files/opendap_form_help.html" by default; otherwise, this is locataion where an HTML document that explains the page can be found.

void dap_html_form::write_simple_variable	(	FILE *	os,
		BaseType *	var
	)

This function is used by the Byte, ..., URL types to write their entries in the HTML Form.

Write out the HTML for simple type variables.

More complex classes do something else. Output HTML entry for Scalars

Parameters

os	Write to this output sink.
name	The name of the variable.
type	The name of the variable's data type.

This is used not only for single instances of simple types, but also for those types when they appear within Structure and Sequence types.

Parameters

name	The name of the varaible.

Parameters

strm	Write to this output stream.
name	The name of the variable.
