Package org.biojava.bio.symbol

Class DummySymbolList

java.lang.Object

org.biojava.utils.AbstractChangeable

org.biojava.bio.symbol.AbstractSymbolList

org.biojava.bio.symbol.DummySymbolList

All Implemented Interfaces:

Serializable, SymbolList, Changeable

public class DummySymbolList
extends AbstractSymbolList
implements Serializable

Symbol list which just consists of non-informative symbols. A DummySymbolList can be constructed over any Alphabet, and may be of any length. Calls to the symbolAt method will always return the non-informative symbol for the alphabet in question (i.e. 'n' for DNA, 'X' for protein, etc.). If you wish to work with Feature objects, but don't have the actual sequence data available, you can construct a SimpleSequence from a DummySequence, and create features. on that.

Specified by:

getAlphabet in interface SymbolList

Returns:

the alphabet

length

public int length()

Description copied from interface: SymbolList

The number of symbols in this SymbolList.

Specified by:

length in interface SymbolList

Description copied from interface: SymbolList

Return the symbol at index, counting from 1.

Specified by:

symbolAt in interface SymbolList

Parameters:

i - the offset into this SymbolList

Returns:

the Symbol at that index
