public int getAbsentCount()

Description copied from interface: MasterStorage

Number of absent structures.

Specified by:

getAbsentCount in interface MasterStorage<String>

Returns:

Number of absent structures.

isPresent

public boolean isPresent(int index)
                  throws IndexOutOfBoundsException

Description copied from interface: MasterStorage

Check if given entity is present.

Specified by:

isPresent in interface MasterStorage<String>

Parameters:

index - Structure index

Returns:

true when structure is present

Throws:

IndexOutOfBoundsException - when index is less than 0 or greater or equal than MasterStorage.size()

public Optional<String> get(int index)

Description copied from interface: MasterStorage

Get given structure identified with an index.

Specified by:

get in interface MasterStorage<String>

Parameters:

index - Structure index

Returns:

Structure if present

serialize

public void serialize(ObjectOutputStream oos,
                      SubProgressObserver po)
               throws IOException

Write into serialized format.

Parameters:

oos - Stream to write to

po - Progress observer to track progress. Work units reflect non-skipped stored entities. Will be closed upon completion.

Throws:

IOException - re-thrown

deserialize

public static CompactStringStorage deserialize(ObjectInputStream ois,
                                               SubProgressObserver po)
                                        throws IOException,
                                               ClassNotFoundException

Deserialize from an object input stream.

Parameters:

ois - Stream to read from

po - Progress observer to track progress. Work units reflect non-skipped stored entities. Will be closed upon completion.

Returns:

deserialized instance

Throws:

ClassNotFoundException - propagated

IOException - propagated

writeIndirected

public void writeIndirected(ObjectOutputStream oos,
                            SubProgressObserver po)
                     throws IOException

Description copied from interface: IndirectSerializable

Write Deserializer conform representation. First a Deserializer instance is written to the stream using ObjectOutputStream.writeObject(java.lang.Object). This instance is capable of deserializing the content written next.

Specified by:

writeIndirected in interface IndirectSerializable<MasterStringStorage>

Parameters:

oos - Stream to write to

po - Observer to track progress; will be closed upon finishing

Throws:

IOException - delegated from underlying ObjectOutputStream accesses
