Field Detail

values

public ARRAYTYPE values

Array of all the values in the feature vector

ArrayFeatureVector

public ArrayFeatureVector()

Method Detail

getVector

public ARRAYTYPE getVector()

Get the underlying representation

Specified by:

getVector in interface FeatureVector

Returns:

the feature as an array

subvector

public abstract ArrayFeatureVector<ARRAYTYPE> subvector(int beginIndex)

Returns a new featurevector that is a subsequence of this vector. The subsequence begins with the element at the specified index and extends to the end of this vector.

Parameters:

beginIndex - the beginning index, inclusive.

Returns:

the specified subvector.

Throws:

IndexOutOfBoundsException - if beginIndex is negative or larger than the length of this ArrayFeatureVector object.

subvector

public abstract ArrayFeatureVector<ARRAYTYPE> subvector(int beginIndex,
                                                        int endIndex)

Returns a new string that is a subvector of this vector. The subvector begins at the specified beginIndex and extends to the element at index endIndex - 1. Thus the length of the subvector is endIndex-beginIndex.

Parameters:

beginIndex - the beginning index, inclusive.

endIndex - the ending index, exclusive.

Returns:

the specified subvector.

Throws:

IndexOutOfBoundsException - if the beginIndex is negative, or endIndex is larger than the length of this ArrayFeatureVector object, or beginIndex is larger than endIndex.
