Class LatticeCollection

java.lang.Object
  edu.unh.sdb.lattice.LatticeCollection

public class LatticeCollection
extends java.lang.Object

The LatticeCollection class provides for a list of Lattices with customary list functionality. The list was intended to be populated either by reading a database or by processing some Data Description Language. The list is only allowed to grow. Elements are never deleted from the list.

Constructor Summary

LatticeCollection()
default constructor

Method Summary

void	add(Lattice lattice) Add a Lattice to the end of the list
Lattice	get(int i) Returns the Lattice at the designated index or null Lattice object if no more exists.
Lattice	get(java.lang.String s) Returns the Lattice object corresponding to the Lattice named by the string.
Lattice	getElementAt(int i) Returns the Lattice at the designated index or null Lattice object if no more exists.
Lattice	getLattice(java.lang.String s) Returns the Lattice object corresponding to the Lattice named by the string
int	indexOf(java.lang.String s) Returns the integer index of the Lattice corresponding to the Lattice named by the string.
int	indexOfName(java.lang.String s) Returns the integer index value for the Lattice denoted by string.
void	merge(LatticeCollection latticeCollection) if name exists in both collections, the new one is discarded
boolean	nameExists(java.lang.String s) Returns true if Lattice named by String is in the list
Lattice	next() returns the next Lattice object or null Lattice object if no more exists
void	rewind() Resets the index to beginning of the list
int	size() Returns the number of elements stored this Lattice collection as an integer
java.lang.String	toString() for debugging - prints the total number of Lattice collections stored.

Constructor Detail

LatticeCollection

public LatticeCollection()

default constructor

Method Detail

next

public Lattice next()

returns the next Lattice object or null Lattice object if no more exists

getElementAt

public Lattice getElementAt(int i)

Returns the Lattice at the designated index or null Lattice object if no more exists. Returns a null Lattice object if index does not exist.

get

public Lattice get(int i)

Returns the Lattice at the designated index or null Lattice object if no more exists. Returns a null Lattice object if index does not exist. This is a shorthand method to getElementAt() added for compatibility with SDB naming conventions.

add

public void add(Lattice lattice)

Add a Lattice to the end of the list

rewind

public void rewind()

Resets the index to beginning of the list

indexOfName

public int indexOfName(java.lang.String s)

Returns the integer index value for the Lattice denoted by string. Returns -1 if the Lattice name does not exist

nameExists

public boolean nameExists(java.lang.String s)

Returns true if Lattice named by String is in the list

indexOf

public int indexOf(java.lang.String s)

Returns the integer index of the Lattice corresponding to the Lattice named by the string. If name does not exist, a null Lattice will be returned

getLattice

public Lattice getLattice(java.lang.String s)

Returns the Lattice object corresponding to the Lattice named by the string

get

public Lattice get(java.lang.String s)

Returns the Lattice object corresponding to the Lattice named by the string. This is a shorthand for getLattice(String) to comply with SDB naming conventions.

size

public int size()

Returns the number of elements stored this Lattice collection as an integer

merge

public void merge(LatticeCollection latticeCollection)

if name exists in both collections, the new one is discarded

toString

public java.lang.String toString()

for debugging - prints the total number of Lattice collections stored. Later will give names of each Lattice

Overrides:
