Class InputSequenceObject<T>

java.lang.Object
  calhoun.analysis.crf.io.InputSequenceObject<T>

All Implemented Interfaces:

InputSequence<T>

public class InputSequenceObject<T>
extends java.lang.Object
implements InputSequence<T>

an input sequence where the elements of the sequence are objects.

Constructor Summary

InputSequenceObject()
default constructor

InputSequenceObject(T[] t)
creates an input sequence using data from this Object array

Method Summary

InputSequence<?>	getComponent(java.lang.String name) For input sequences that are a composite of several different input objects, returns a particular component of the input.
T	getX(int ix) retrieves the input value at a position in the input sequence.
int	length() Returns the length of this sequence
java.util.Collection<java.lang.String>	listComponents() For input sequences that are a composite of several different input objects, returns a list of the names of the components in this input sequence.
InputSequence<T>	subSequence(int start, int end) tTakes a subinterval of the input sequence with given start-end coordinates which are relative coordinates, 1-based, and inclusive.

Constructor Detail

InputSequenceObject

public InputSequenceObject()

default constructor

InputSequenceObject

public InputSequenceObject(T[] t)

creates an input sequence using data from this Object array

Parameters:

t - a an object array containing the input sequence

Method Detail

getX

public T getX(int ix)

Description copied from interface: InputSequence

retrieves the input value at a position in the input sequence.

Specified by:

getX in interface InputSequence<T>

Parameters:

ix - the index position at which to get the input. This is a zero-based index.

Returns:

the object at this position in the input.

length

public int length()

Description copied from interface: InputSequence

Returns the length of this sequence

Specified by:

length in interface InputSequence<T>

Returns:

length

getComponent

public InputSequence<?> getComponent(java.lang.String name)

Description copied from interface: InputSequence

For input sequences that are a composite of several different input objects, returns a particular component of the input. For simple input sequences that just return an object, this method should throw UnsupportedOperationException.

Specified by:

getComponent in interface InputSequence<T>

Parameters:

name - the name of the input component to return

Returns:

the input sequence representing this component

listComponents

public java.util.Collection<java.lang.String> listComponents()

Description copied from interface: InputSequence

For input sequences that are a composite of several different input objects, returns a list of the names of the components in this input sequence. For simple input sequences that just return an object, this method should throw UnsupportedOperationException.

Specified by:

listComponents in interface InputSequence<T>

Returns:

a collection containing the component names

subSequence

public InputSequence<T> subSequence(int start,
                                    int end)

Description copied from interface: InputSequence

tTakes a subinterval of the input sequence with given start-end coordinates which are relative coordinates, 1-based, and inclusive. Thus 1-10 will mean returning a new InputSequence which is the first 10 positions of the current one.

An implementation that does not support subsetting should throw an UnsupportedOperationException

Specified by:

subSequence in interface InputSequence<T>

Parameters:

start - the 1-based index of the first position of the input to retrieve.

end - the 1-based index of the last position of the input to retrieve.

Returns:

an input sequence which is a sbusequence of the original sequence.
