Method Detail

getSymbol

public I getSymbol(int index)

Description copied from interface: Alphabet

Returns the symbol with the given index in this alphabet.

Specified by:

getSymbol in interface Alphabet<I>

Parameters:

index - the index of the requested symbol.

Returns:

symbol with the given index.

getSymbolIndex

public int getSymbolIndex(I symbol)

Description copied from interface: Alphabet

Returns the index of the given symbol in the alphabet.

Specified by:

getSymbolIndex in interface Alphabet<I>

Parameters:

symbol - the symbol whose index should be determined

Returns:

the index of the given symbol

containsSymbol

public boolean containsSymbol(I symbol)

Description copied from interface: Alphabet

Checks whether the given symbol is part of the alphabet.

Caution: the default implementation is rather inefficient and should be overridden, if possible.

Specified by:

containsSymbol in interface Alphabet<I>

Parameters:

symbol - the symbol to check

Returns:

true iff the symbol is part of the alphabet

size

public int size()

Description copied from interface: ArrayWritable

The size of this container.

Specified by:

size in interface ArrayWritable<I>

Specified by:

size in interface Collection<I>

Specified by:

size in interface List<I>

Specified by:

size in class AbstractCollection<I>
