Methods

Modifier and Type	Method and Description
void	add(SyntacticRelation r) adds a SyntacticRelation to the set.
void	addAll(Collection c) adds all the elements of c, which should be SyntacticRelations, to the set.
void	addInverses() for each relation in the SyntacticRelationSet of the form 'X rel Y', adds an inverse relation of the form 'Y rel-1 X'.
void	addRelations(Document doc) search Document doc for syntactic relatioms (encoded as features on annotations) and add them to the SyntacticRelationSet.
boolean	equals(Object o)
SyntacticRelation	get(int i) returns the i-th relation in the set, where i is non-negative and less than the size of the set.
SyntacticRelation	getRelation(int from, int to) return the first relation whose source is at position from and whose target is at position to, or null if no such relation exists.
SyntacticRelation	getRelation(int from, String type) return the first relation whose source is at position from and whose type is type, or null if no such relation exists.
SyntacticRelationSet	getRelationsFrom(int from) return a SyntacticRelationSet containing those relations whose source is at position from.
SyntacticRelation	getRelationTo(int to) return the first relation whose target is at position to or null if no such relation exists.
int	hashCode()
static void	main(String[] args)
void	read(BufferedReader br) reads the SyntacticRelationSet from BufferedReader br.
void	readRelations(String fileName) reads relations (in GLARF tuple format) from 'fileName'.
int	size() returns the number of SyntacticRelations in the set.

Method Detail

addRelations

public void addRelations(Document doc)

search Document doc for syntactic relatioms (encoded as features on annotations) and add them to the SyntacticRelationSet. Looks for features on the list relationTypes.

add

public void add(SyntacticRelation r)

adds a SyntacticRelation to the set.

addAll

public void addAll(Collection c)

adds all the elements of c, which should be SyntacticRelations, to the set.

size

public int size()

returns the number of SyntacticRelations in the set.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

get

public SyntacticRelation get(int i)

returns the i-th relation in the set, where i is non-negative and less than the size of the set.

getRelation

public SyntacticRelation getRelation(int from,
                            int to)

return the first relation whose source is at position from and whose target is at position to, or null if no such relation exists.

getRelation

public SyntacticRelation getRelation(int from,
                            String type)

return the first relation whose source is at position from and whose type is type, or null if no such relation exists.

getRelationsFrom

public SyntacticRelationSet getRelationsFrom(int from)

return a SyntacticRelationSet containing those relations whose source is at position from.

getRelationTo

public SyntacticRelation getRelationTo(int to)

return the first relation whose target is at position to or null if no such relation exists.

toString

public String toString()

return a printable version of the SyntacticRelationSet.

Overrides:

toString in class Object

write

public void write(PrintWriter pw)

read

public void read(BufferedReader br)
          throws IOException

reads the SyntacticRelationSet from BufferedReader br. The input should be one relation per line, consisting of 5 fields separated by "|".

Throws:

IOException

readRelations

public void readRelations(String fileName)

reads relations (in GLARF tuple format) from 'fileName'. Current format is relation | PA-relation | ... (total of 25 fields)

addInverses

public void addInverses()

for each relation in the SyntacticRelationSet of the form 'X rel Y', adds an inverse relation of the form 'Y rel-1 X'.

main

public static void main(String[] args)
