class Segment

class Segment

module segment

The documentation is here.

Instances of this class are used for Partition class, but it may be useful to handle them.

A Segment is made of

two positions (begin and end), included in the segment;
a list of descriptors numbers (optionaly empty);
a float for the value of the segment (optionaly zero).
a string corresponding to a descriptor pattern (optionaly this string is empty);

Construction

__init__

Optional keywords:

beg=d: begin position is d (default: 0);
end=f: end position is f (default: 0);
val=v: value is v (default:0).
str=l: descriptor numbers are a copy of list l (default: []);
mot=m: descriptor is string m (default: "");

read_str

builds from a string in specific format; returns True if parsing is ok, False otherwise;

copy

returns a copy of this Segment.

Handling

g_deb: gets the first position;
g_fin: gets the last position;
g_num: gets the list of descriptors numbers;
g_word: gets the string of the pattern;
g_val: gets the value;
deb: returns the first position;
fin: returns the last position;
num: returns the list of descriptors numbers;
word: returns the string of the pattern;
val: returns the value;
__len__: returns the length of the Segment, ie fin-deb+1.

Input-Output

Specific format is:

description

<begin-end>sequence_of_descriptors_numbers:value:descriptor_pattern

if sequence_of_descriptors_numbers is empty, it is not output

if value is zero, it is not output

if descriptor_pattern is empty, it is not output

examples

<0-123>1,2:-5.0:+{A(-1)CG}T

<5-3922>:0.45:

<87-332>1::

__str__: outputs in specific format;
abr: outputs in specific format, without the descriptor pattern.
