java.lang.Objectde.fu_berlin.ties.classify.feature.FeatureVector
A feature vector contains the features representing an instance. Subclasses
must implement the store()
method to provide a collection for
storing the features.
Instances of this class are thread-safe if and only if the provided collection is thread-safe (normally this won't be the case).
Constructor Summary | |
FeatureVector()
Creates a new instance. |
Method Summary | |
void |
add(Feature feature)
Adds a feature to this vector. |
void |
addAll(Collection coll)
Adds all of the features in the specified Collection to this vector, in the order they are returned by the specified Collection's Iterator. |
void |
addAll(FeatureVector fv)
Adds all of the features in the specified feature vector to this vector, in the order they are returned by the specified feature vector. |
void |
addAllTokens(CharSequence text,
TextTokenizer tokenizer)
Tokenizes a text, creating and adding a feature for each token. |
CharSequence |
flatten()
Flattens the contained features into a single character sequence, without including comments. |
CharSequence |
flatten(boolean inclComments)
Flattens a list of features into a single character sequence. |
Iterator |
iterator()
Returns an iterator over the Feature s stored in this vector. |
