owa_text.multi_line data type - data type for holding large amounts of text.

owa_text.new_row_list - creates a new row_list.

owa_text.print_multi procedure - prints out the contents of a multi_list.

owa_text.print_row_list procedure - prints out the contents of a row_list.

owa_text.row_list data type - data type for holding data to be processed.

owa_text.stream2multi procedure - converts a varchar2 to a multi_line type.

owa_text.vc_arr data type - data type for holding large amounts of text.

8.2 owa_text.add2multi procedure

This procedure adds content to an existing owa_text.multi_line data type.

Table 8-1 owa_text.add2multi procedure

owa_text.add2multi(
   stream         in       varchar2
   mline          in out   multi_line
   continue       in       boolean   DEFAULT TRUE);

8.3 owa_text.multi_line data type

This data type is a PL/SQL record that holds large amounts of text. The rows field, of type owa_text.vc_arr data type, contains the text data in the record.

Table 8-2 owa_text.multi_line data type

type multi_line is record (
   rows           vc_arr,
   num_rows       integer,
   partial_row    boolean);

8.4 owa_text.new_row_list

This function or procedure creates a new owa_text.row_list data type. The function version uses no parameters and returns a new empty row_list. The procedure version creates the row_list data type as an output parameter.

Table 8-3 owa_text.new_row_list

/* procedure */
owa_text.new_row_list(rlist out row_list);
/* function */
owa_text.new_row_list return row_list;

8.5 owa_text.print_multi procedure

This procedure uses htp.print, htp.prn to print the "rows" field of the owa_text.multi_line data type.

Table 8-4 owa_text.print_multi procedure

owa_text.print_multi(mline in multi_line);

8.6 owa_text.print_row_list procedure

This procedure uses htp.print, htp.prn to print the "rows" field of the owa_text.row_list data type.

Table 8-5 owa_text.print_row_list procedure

owa_text.print_row_list(rlist in row_list);

8.7 owa_text.row_list data type

This is the data type for holding data to be processed.

Table 8-6 owa_text.row_list data type

type row_list is record (
   rows           int_arr,
   num_rows       integer);
int_arr is defined as:
type int_arr is table of integer index by binary_integer;

8.8 owa_text.stream2multi procedure

This procedure converts a string to a multi_line data type.

Table 8-7 owa_text.stream2multi procedure

8.9 owa_text.vc_arr data type

This is a component of the owa_text.multi_line data type.
