Constructor Detail

MemorySentencebank

public MemorySentencebank()

Create a new sentence bank.

MemorySentencebank

public MemorySentencebank(SentenceReaderFactory srf)

Create a new sentence bank.

Parameters:

srf - the factory class to be called to create a new SentenceReader

MemorySentencebank

public MemorySentencebank(int initialCapacity)

Create a new Sentencebank.

Parameters:

initialCapacity - The initial size of the underlying Collection, (if a Collection-based storage mechanism is being provided)

MemorySentencebank

public MemorySentencebank(int initialCapacity,
                          SentenceReaderFactory srf)

Method Detail

clear

public void clear()

Empty a Sentencebank.

Specified by:

clear in interface Collection

Specified by:

clear in class Sentencebank

loadPath

public void loadPath(File path,
                     FileFilter filt)

Load sentences from given directory.

Specified by:

loadPath in class Sentencebank

Parameters:

path - file or directory to load from

processFile

public void processFile(File file)

Load a collection of parse sentences from the file of given name. Each sentence may optionally be encased in parens to allow for Penn Sentencebank style sentences. This methods implements the FileProcessor interface.

Specified by:

processFile in interface FileProcessor

file - file to load a sentence from

See Also:

for traversing directories

get

public Object get(int i)

Get a sentence by index from the Sentencebank.

apply

public void apply(SentenceProcessor sp)

Specified by:

apply in class Sentencebank

Parameters:

sp - The SentenceProcessor to be applied

iterator

public Iterator iterator()

Return an Iterator over Sentences in the Sentencebank

Specified by:

iterator in interface Collection

Specified by:

iterator in class Sentencebank

size

public int size()

Returns the size of the Sentencebank. Provides a more efficient implementation than the one for a generic Sentencebank

Specified by:

size in interface Collection

Overrides:

size in class Sentencebank

Returns:

the number of trees in the Sentencebank

main

public static void main(String[] args)

Loads sentencebank grammar from first argument and print it.

Parameters:

args - array of command-line arguments
