Class AbstractStringExtractor

java.lang.Object

de.jstacs.io.AbstractStringExtractor

All Implemented Interfaces:

Enumeration<String>

Direct Known Subclasses:

InfixStringExtractor, LimitedStringExtractor, SimpleStringExtractor, SparseStringExtractor, StringExtractor

public abstract class AbstractStringExtractor
extends Object
implements Enumeration<String>

This class implements the reader that extracts strings. The class ignores lines starting with a given character, since those lines are treated as comments. If the user does not specify this character, it is set to "#" internally. If the user specifies this character as ">", the file or String will be treated as in FastA-format, i.e. lines beginning with ">" will be stripped and the lines between two ">" (or until the end of the file) will be appended to form a new String.
