Method Detail

getPath

public static String getPath()

Returns the full path to the GLPK Solver binary in a String.

Returns:

Full path to the GLPK Solver binary.

isBinaryValid

public static boolean isBinaryValid()

Verifies whether the GLPK binary is valid. See FileUtils.isBinaryValid(String, String, String, boolean) for details.

Returns:

True if the binary found at path provided by getPath() is a valid GLPK Solver binary, false otherwise.

isBinaryValid

public static boolean isBinaryValid(String binaryPath)

Verifies whether the provided path to GLPK binary is valid. See FileUtils.isBinaryValid(String, String, String, boolean) for details.

Parameters:

binaryPath - Path to the binary to check.

Returns:

True if the binary found at path provided is a valid GLPK Solver binary, false otherwise.

getVersion

public static String getVersion()

Returns the first line that GLPK returns when run with "-v" option, hopefully containing the version of GLPK.

Returns:

String containing GLPK identification and version. null if something goes wrong.

getName

public static String getName(AttributeMappingId mapping)

Returns a "name" for the provided attribute mapping.

Parameters:

mapping - Mapping to get a name for.

Returns:

Name of the provided mapping constructed in the following fashion: element name-attribute name

getName

public static String getName(AttributeMappingId mapping,
                             char separator)

Returns a "name" for the provided attribute mapping, using the provided separator character.

Parameters:

mapping - Mapping to get a name for.

separator - Separator to use.

Returns:

Name of the provided mapping constructed in the following fashion: element name{separator}attribute name

getParameters

public static String[] getParameters(int timeLimit)
