 java.lang.Enum<CSVFormat>

 org.jgrapht.io.CSVFormat

 All Implemented Interfaces:
Serializable
,Comparable<CSVFormat>
@Deprecated public enum CSVFormat extends Enum<CSVFormat>
Deprecated.No longer used.Supported CSV formats.
Format
EDGE_LIST
contains one edge per line. The following examplea,b b,c
represents a graph with two edges: a>b and b>c. 
Format
ADJACENCY_LIST
contains the adjacency list of each vertex per line. The first field on a line is a vertex while the remaining fields are its neighbors.a,b b,c,d c,a,c,d
represents a graph with edges: a>b, b>c, b>d, c>a, c>c, c>d.Mixed variants of
EDGE_LIST
andADJACENCY_LIST
are also considered valid. As an example consider the following inputa,b b,a d,a c,a,b b,d,a
which represents a graph with edges: a>b, b>a, d>a, c>a, c>b, b>d, b>a. Multiple occurrences of the same edge result into a multigraph.Weighted variants are also valid if
CSVFormat.Parameter.EDGE_WEIGHTS
is set. In this case the target vertex must be followed by the edge weight. The following example illustrates the weighted variant:a,b,2.0 b,a,3.0 d,a,2.0 c,a,1.5,b,2.5 b,d,3.3,a,5.5

Format
MATRIX
outputs an adjacency matrix representation of the graph. Each line represents a vertex. The following0,1,0,1,0 1,0,0,0,0 0,0,1,0,0 0,1,0,1,0 0,0,0,0,0
represents a graph with five vertices 1,2,3,4,5 which contains edges: 1>2, 1>4, 2>1, 3>3, 4>2, 4>4.In case
CSVFormat.Parameter.MATRIX_FORMAT_ZERO_WHEN_NO_EDGE
is not set the equivalent format would be:,1,,1, 1,,,, ,,1,, ,1,,1, ,,,,
Weighted variants are also valid if
CSVFormat.Parameter.EDGE_WEIGHTS
is set. The above example would then be:,1.0,,1.0, 1.0,,,, ,,1.0,, ,1.0,,1.0, ,,,,
If additionallyCSVFormat.Parameter.MATRIX_FORMAT_ZERO_WHEN_NO_EDGE
is set then a zero as an integer means that the corresponding edge is missing, while a zero as a double means than the edge exists and has zero weight.If parameter
CSVFormat.Parameter.MATRIX_FORMAT_NODEID
is set then node identifiers are also included as in the following example:,a,b,c,d,e a,,1,,1, b,1,,,, c,,,1,, d,,1,,1, e,,,,,
In the above example the first line contains the node identifiers and the first field of each line contain the vertex it corresponds to. In case node identifiers are present lineshuffled input is also valid such as:,a,b,c,d,e c,,,1,, b,1,,,, e,,,,, d,,1,,1, a,,1,,1,
The last example represents the graph with edges: a>b, a>d, b>a, c>c, d>b, d>d.

Method Detail

values
public static CSVFormat[] values()
Deprecated.Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (CSVFormat c : CSVFormat.values()) System.out.println(c);
 Returns:
 an array containing the constants of this enum type, in the order they are declared

valueOf
public static CSVFormat valueOf(String name)
Deprecated.Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.) Parameters:
name
 the name of the enum constant to be returned. Returns:
 the enum constant with the specified name
 Throws:
IllegalArgumentException
 if this enum type has no constant with the specified nameNullPointerException
 if the argument is null
