Field Detail

granularity

public Granularity granularity

The granularity in the calendric system that the LatticeNode is representing.

coarserEdges

public java.util.Hashtable coarserEdges

A hash between [destination granularity --> edge to dest. granularity]. Represents the edges that connects this lattice node to other nodes which represent coarser granularities in the lattice.

congruentEdges

public java.util.Hashtable congruentEdges

A hash between [destination granularity --> edge to dest. granularity]. Represents the edges that connects this lattice node to other nodes which represent congruent granularities in the lattice.

finerEdges

public java.util.Hashtable finerEdges

A hash between [destination granularity --> edge to dest. granularity]. Represents the edges that connects this lattice node to other nodes which represent finer granularities in the lattice.

Constructor Detail

GranularityLattice.LatticeNode

public GranularityLattice.LatticeNode(Granularity g)

Construct a LatticeNode by setting the node's granularity to the given granularity.

Parameters:

g - the granularity this node is to represent

GranularityLattice.LatticeNode

public GranularityLattice.LatticeNode(Granularity g,
                                      java.util.Hashtable cEdges,
                                      java.util.Hashtable cgntEdges,
                                      java.util.Hashtable fEdges)

Construct a LatticeNode by setting the node's granularity to the given granularity and setting the node's edges to the given lists of edges.

Parameters:

g - the granularity this node is to represent

cEdges - the list of edges that lead to granularities coarser than this one

cgntEdges - the list of edges that lead to granularities congruent to this one

fEdges - the list of edges that lead to granularities finer than this one

Method Detail

equals

public boolean equals(java.lang.Object o)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class java.lang.Object

Parameters:

o - the object with which to compare this one

Returns:

true<\code> if this object is the same as the obj argument; false<\code> otherwise

toString

public java.lang.String toString()

Returns a string representation of the lattice node.

Overrides:

toString in class java.lang.Object

Returns:

a String representation of the lattice node.
