Class ArrayPairList<A,B>

java.lang.Object
java.util.AbstractCollection<E>
java.util.AbstractList<E>
java.util.ArrayList<Pair<A,B>>
oracle.javatools.util.ArrayPairList<A,B>

Type Parameters:

A - a generic placeholder for any type which will be the first of the Pair.

B - a generic placeholder for any type which will be the second of the Pair

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<Pair<A,B>>, java.util.Collection<Pair<A,B>>, java.util.List<Pair<A,B>>, java.util.RandomAccess, PairList<A,B>

public class ArrayPairList<A,B>

extends java.util.ArrayList<Pair<A,B>>

implements PairList<A,B>

ArrayPairList is an ArrayList that extends ArrayList and implements the PairList (which extends the List interface) to support Pairs of generic types, say Pair of A,B. The class behaves like an array list except for various search and selection methods which have *FirstType() versions, for example indexOfFirstType( A a) which looks for a Pair whose first member of type A matches the argument A.

Method Summary

boolean	containsFirstType(A a) Returns true if the list conatains an object of type Pair whose first component matches the argument.
boolean	containsSecondType(B b) Returns true if the list conatains an object of type Pair whose second component matches the argument.
int	indexOfFirstType(A a) Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.
int	indexOfSecondType(B b) Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.
int	lastIndexOfFirstType(A a) Returns the index of the last occurrence of the specified element, where the first element matches the first element of the entry in this list, or -1 if this list does not contain the element.
int	lastIndexOfSecondType(B b) Returns the index of the last occurrence of the specified element, where the second element matches the second element of the entry in this list, or -1 if this list does not contain the element.
boolean	removeByFirstType(A a) Removes the first occurence of a Pair whose first matches the first of an entry in the list.
boolean	removeBySecondType(B b) Removes the first occurence of a Pair whose second element matches the second of Pair entry in the list.

Method Detail

containsFirstType

public boolean containsFirstType(A a)

Returns true if the list conatains an object of type Pair whose first component matches the argument.

Specified by:

containsFirstType in interface PairList<A,B>

Parameters:

a - The object to lookup, standard arraylist semantics for equality are used.

Returns:

boolean true if a Pair with the same first element exists in the list.

containsSecondType

public boolean containsSecondType(B b)

Description copied from interface: PairList

Returns true if the list conatains an object of type Pair whose second component matches the argument.

Specified by:

containsSecondType in interface PairList<A,B>

Parameters:

b - The object to lookup, standard arraylist semantics for equality are used.

Returns:

boolean true if a Pair with the same second element exists in the list.

indexOfFirstType

public int indexOfFirstType(A a)

Description copied from interface: PairList

Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element. More formally, returns the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))) , or -1 if there is no such index.

Specified by:

indexOfFirstType in interface PairList<A,B>

Returns:

indexOfSecondType

public int indexOfSecondType(B b)

Description copied from interface: PairList

Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element. More formally, returns the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))) , or -1 if there is no such index.

Specified by:

indexOfSecondType in interface PairList<A,B>

Returns:

lastIndexOfFirstType

public int lastIndexOfFirstType(A a)

Description copied from interface: PairList

Returns the index of the last occurrence of the specified element, where the first element matches the first element of the entry in this list, or -1 if this list does not contain the element. *

Specified by:

lastIndexOfFirstType in interface PairList<A,B>

Returns:

lastIndexOfSecondType

public int lastIndexOfSecondType(B b)

Description copied from interface: PairList

Returns the index of the last occurrence of the specified element, where the second element matches the second element of the entry in this list, or -1 if this list does not contain the element.

Specified by:

lastIndexOfSecondType in interface PairList<A,B>

Returns:

removeByFirstType

public boolean removeByFirstType(A a)

Description copied from interface: PairList

Removes the first occurence of a Pair whose first matches the first of an entry in the list. Returns false in no match was found.

Specified by:

removeByFirstType in interface PairList<A,B>

Parameters:

a - The object of type A to be removed.

Returns:

boolean true if a match was found and removed, otherwise false.

removeBySecondType

public boolean removeBySecondType(B b)

Description copied from interface: PairList

Removes the first occurence of a Pair whose second element matches the second of Pair entry in the list. Returns false in no match was found.

Specified by:

removeBySecondType in interface PairList<A,B>

Parameters:

b - The object of type B to be removed.

Returns:

boolean true if a match was found and removed, otherwise false.
