name_zla = line_in_cave list
Where is,
Name_zla - a line of letters, numbers, and the symbol '_', starting not with numbers
line_in_coats - a arbitrary line in double coats, which does not contain symbols of translation of the line and double coats
List = {Use [Use ... ] }
It is necessary to write a parser that receives a file containing one root nod,
and build in memory a wood-looking presentation of data.Each nod is assigned a whole number ID.Then mix the data into text.
file (or in the BD table) of the following string: (node ID, id of the upper nod, nod name, value in the nod)
If the option is selected with BD, the structure of the table can be as follows:
create table tree_table (
node_id number not null primary key
parent_id number references tree_table( node_id ),
node_name varchar2(100)
Node_value varchar2 (1000)
and the
If there are errors in the data format, issue the message of the type "False data format" and complete the work.Examples of hierarchical structure:
The shape = {
Type = “Tetrahedron”
The vertices = {
point = { x = "1" y = "0" z = "0"
The
point= { x = "0" y = "1" z = "0" }
point ={ x = "0" y = "0" z = "1" }
point = { x = "1" y = "1" z = "1" }
The
color = { r = "0xFF" g = "0x00" b = "0x80" alpha = "0x80" }a="25"
The
Examples of the final file:
(1 of 0, shape )
(2, 1, type and tetrahedron)
(3, 1 and vertices)
(4, 3 and 3 points)
(5, 4, x and 1 )
(6, 4, y and 0 )
(7, 4, z and 0 )
(8, 3 and 3 points)
(9, 8, x and 0 )
(10, 8 and 1)
(11, 8, z and 0)
(12, 3 and 3 points)
(13, 12, x and 0)
(14, 12, y and 0)
(15, 12, z and 1)
(16, 3 and 3 points)
(17, 16, x and 1)
(18, 16, and 1)
(19, 16, z and 1)
(20, 1 and 1 color)
(21, 20, r, 0xFF and 0xFF)
(22, 20, g and 0x00)
