Method Summary

static java.util.Vector	matricesToNodes(java.util.Vector matrices, java.lang.Class nodeClass, java.lang.Class edgeClass) Converts the network(s) described in matrices to a list of nodes and links of type nodeClass and type edgeClass. matrices must contain AdjacencyMatrices that describe the same nodes, that is, each AdjacencyMatrix must contain the same list of node labels, in the same order.
static java.util.Vector	nodesToMatrices(java.util.List nodeList) Deprecated. use nodesToMatrices(List nodeList, int matrixType) instead.
static java.util.Vector	nodesToMatrices(java.util.List nodeList, int matrixType) Converts the network(s) described by a list Nodes to a Vector of AdjacencyMatrices.

Method Detail

nodesToMatrices

public static java.util.Vector nodesToMatrices(java.util.List nodeList)

Deprecated. use nodesToMatrices(List nodeList, int matrixType) instead.

Converts the network(s) described by a list Nodes to a Vector of AdjacencyMatrices.

Returns:

a Vector of AdjacencyMatrices

nodesToMatrices

public static java.util.Vector nodesToMatrices(java.util.List nodeList,
                                               int matrixType)

Converts the network(s) described by a list Nodes to a Vector of AdjacencyMatrices.

The matrixType parameter refers to the size of the matrix elements, the ij values. A matrix of type of NetworkConstants.BINARY contains on 0 or 1 as elements. A matrix of type of NetworkConstants.SMALL contains values of -127 - 127 as elements. And a matrix of type NetworkConstants.LARGE contains anything else. Matrix ij values are assigned the edge strength of an edge, so unless you have explicitly set an edge strength of greater than 1, use NetworkConstants.BINARY.

Parameters:

nodeList - the list of nodes that is the source for the matrix

matrixType - the type of the matrix. type refers to the size of the matrix elements (ij values) and can be one of NetworkConstants.BINARY, NetworkConstants.LARGE, NetworkConstants.SMALL

Returns:

a Vector of AdjacencyMatrices

matricesToNodes

public static java.util.Vector matricesToNodes(java.util.Vector matrices,
                                               java.lang.Class nodeClass,
                                               java.lang.Class edgeClass)

Converts the network(s) described in matrices to a list of nodes and links of type nodeClass and type edgeClass. matrices must contain AdjacencyMatrices that describe the same nodes, that is, each AdjacencyMatrix must contain the same list of node labels, in the same order.

Parameters:

matrices - a list of AdjacencyMatrices

nodeClass - specifies the type of Nodes to create

edgeClass - specifies the type of Edge to create

Returns:

a list of nodes of the type specified by nodeClass. These nodes will contain edges of type edgeClass
