Class TokenProperty

java.lang.Object
  com.googlecode.whatswrong.TokenProperty

All Implemented Interfaces:

Comparable<TokenProperty>

public class TokenProperty
extends Object
implements Comparable<TokenProperty>

A TokenProperty represents a property of a token, such as the 'Word' or "PoS-Tag' property. A Token then maps such properties to property values, such as "house" or "NN". Each TokenProperty has a name (say 'Word') and an integer 'level' that can be used to define an order on properties. This order is for example used when the properties of a token are stacked under each other in the graphical representation of a token.

Constructor Summary

TokenProperty(int level)
Creates a property with the given level and the name 'Property [level]' where [level] will be replaced with the given level.

TokenProperty(String name)
Creates a property with the given name and level 0.

TokenProperty(String name, int level)
Create new property with given name and level.

Method Summary

int	compareTo(TokenProperty o) First compares the level of the two properties and if these are equal the property names are compared.
boolean	equals(Object o) Two TokenProperty objects are equal iff their names match.
int	getLevel() Returns the level of the property.
String	getName() Returns the name of the property.
int	hashCode() Calculates a hashcode based on the property name.
String	toString() Returns the name of the property.

TokenProperty

public TokenProperty(String name)

Creates a property with the given name and level 0.

Parameters:

name - the name of the property.

TokenProperty

public TokenProperty(int level)

Creates a property with the given level and the name 'Property [level]' where [level] will be replaced with the given level.

Parameters:

level - the level of the property.

Method Detail

toString

public String toString()

Returns the name of the property.

Overrides:

toString in class Object

Returns:

the name of the property.

getName

public String getName()

Returns the name of the property.

Returns:

the name of the property.

getLevel

public int getLevel()

Returns the level of the property.

Returns:

the level of the property.

equals

public boolean equals(Object o)

Two TokenProperty objects are equal iff their names match.

Overrides:

equals in class Object

Parameters:

o - the other property.

Returns:

true iff the property names match.

hashCode

public int hashCode()

Calculates a hashcode based on the property name.

Overrides:

hashCode in class Object

Returns:

a hashcode based on the property name.

compareTo

public int compareTo(TokenProperty o)

First compares the level of the two properties and if these are equal the property names are compared.

Specified by:

compareTo in interface Comparable<TokenProperty>

Parameters:

o - the other property.

Returns:

a value larger than 0 if this level is larger than the other level or the levels equal and this name is lexicographically larger than the other. A value smaller than 0 is returned if this level is smaller than the other level or the levels equal and this name is lexicographically smaller than the other. Otherwise 0 is returned.
