Field Summary

protected List	arguments the arguments associated with the structure, including the verb itself
protected String	lemma the predicate itself, i.e., the root form of the verb in question

Constructor Summary

PAStruct(String lem)

Method Summary

void	addArg(Argument a) Add a single argument to the arguments associated with this PA structures.
boolean	equals(Object o) Checks whether the PAstructs are equivalent.
List	getArgs() return a list of arguments, including the verb itself
String	getLemma() return the lemma, eg the root form of the associated verb.
int	hashCode()
Argument	nthArg(int n) get the nth argument
static PAStruct	ofString(String s) create a predicate argument structure from a canonical string
void	removeArg(Argument a) remove the argument that is the same as a
void	removeArg(int i) remove the argument at position i.
int	size() The number of arguments
String	toString() convert the predicate argument structure to a canonical string.

public void addArg(Argument a)

Add a single argument to the arguments associated with this PA structures.

nthArg

public Argument nthArg(int n)

get the nth argument

Parameters:

n - the n'th argument

removeArg

public void removeArg(int i)

remove the argument at position i.

removeArg

public void removeArg(Argument a)

remove the argument that is the same as a

Parameters:

a - argument to be removed

size

public int size()

The number of arguments

toString

public String toString()

convert the predicate argument structure to a canonical string.

Overrides:

toString in class Object

ofString

public static PAStruct ofString(String s)

create a predicate argument structure from a canonical string

Parameters:

s - the canonical string of the argument.

Throws:

CorruptDataException

equals

Checks whether the PAstructs are equivalent. Ignores the order in which the arguments are stored.

Overrides:

equals in class Object
