Field Detail

BINARY_HEADER

static final byte[] BINARY_HEADER

The header used when writing LocalFeatureLists to streams and files

Method Detail

asDataArray

<Q> Q[] asDataArray(Q[] a)

Get the feature-vector data of the list as a two-dimensional array of data. The number of rows will equal the number of features in the list, and the type <Q>must be compatible with the data type of the features themselves.

Type Parameters:

Q - the data type

Parameters:

a - the array to fill

Returns:

the array, filled with the feature-vector data.

vecLength

int vecLength()

Get the length of the feature-vectors of each local feature if they are constant. This value is used as instantiate new local features in the case that the local feature has a constructor that takes a single integer.

Returns:

the feature-vector length

subList

LocalFeatureList<T> subList(int fromIndex,
                            int toIndex)

Specified by:

subList in interface List<T extends LocalFeature<?,?>>
