Class InputSequenceCharacter

java.lang.Object
  calhoun.analysis.crf.io.InputSequenceCharacter

All Implemented Interfaces:

InputSequence<java.lang.Character>

public class InputSequenceCharacter
extends java.lang.Object
implements InputSequence<java.lang.Character>

an input sequence where the elements of the sequence are string characters.

Constructor Summary

InputSequenceCharacter()
default constructor

InputSequenceCharacter(java.lang.String a)
creates an input sequence using data from this string

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.
java.lang.String	getString() returns the input sequence as a string
java.lang.Character	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<java.lang.Character>	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.
java.lang.String	toString()

Constructor Detail

InputSequenceCharacter

public InputSequenceCharacter()

default constructor

InputSequenceCharacter

public InputSequenceCharacter(java.lang.String a)

creates an input sequence using data from this string

Parameters:

a - string containing characters of the input sequence

Method Detail

getString

public java.lang.String getString()

returns the input sequence as a string

Returns:

a string of the characters

getX

public java.lang.Character 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<java.lang.Character>

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<java.lang.Character>

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<java.lang.Character>

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<java.lang.Character>

Returns:

a collection containing the component names

subSequence

public InputSequence<java.lang.Character> 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<java.lang.Character>

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.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
