Class MWEComparator<T extends IToken>

java.lang.Object

edu.mit.jmwe.util.AbstractIndexComparator<T,IMWE<T>>

edu.mit.jmwe.data.MWEComparator<T>

Type Parameters:

T - the type of token for this comparator

All Implemented Interfaces:

java.util.Comparator<IMWE<T>>

public class MWEComparator<T extends IToken>
extends AbstractIndexComparator<T,IMWE<T>>

A comparator that compares IMWEs by checking which MWE starts earlier in the list of tokens used to construct this comparator. If the two MWEs have the same tokens, uses the part of speech to determine the order.

MWEComparator

public MWEComparator(java.util.List<T> list)

Constructs the comparator from the given list of tokens by mapping each token in the list to its index in the list.

Parameters:

list - the list of objects used to construct this comparator. May not be null.

Throws:

java.lang.NullPointerException - if the given list is null.

jMWE 1.0.0

MWEComparator

public MWEComparator(java.util.Map<T,java.lang.Integer> indexMap)

Constructs the comparator from the given index map of each token in a list to its index in the list.

Parameters:

indexMap - map of each token in a list to its index in the list. May not be null.

Since:

jMWE 1.0.0

Method Detail

compare

public int compare(IMWE<T> one,

earlier

protected boolean earlier(IMWE<T> one,
                          IMWE<T> two)

Internal method used to determine if one multi-word expression appears in the sentence before another.

Parameters:
