Method Detail

isInstalled

public static boolean isInstalled(String cmd)

isInstalled

public boolean isInstalled(boolean recheck)

check, if this solver is installed and can be used.

Specified by:

isInstalled in interface SolverType

Parameters:

recheck - if false, the solver is not checked again, if a cached value for this exists.

Returns:

true, if it is installed.

checkEnvVariable

private static boolean checkEnvVariable(String cmd)

checkForSupport

public boolean checkForSupport()

Description copied from interface: SolverType

Checks for support and returns the result.

Specified by:

checkForSupport in interface SolverType

supportHasBeenChecked

public boolean supportHasBeenChecked()

Description copied from interface: SolverType

returns true if and only if the support has been checked for the currently installed solver.

Specified by:

supportHasBeenChecked in interface SolverType

isSupportedVersion

public boolean isSupportedVersion()

Description copied from interface: SolverType

Returns whether the currently installed version is supported.

Specified by:

isSupportedVersion in interface SolverType

getSolverParameters

public String getSolverParameters()

Description copied from interface: SolverType

The currently used parameters for the solver.

Specified by:

getSolverParameters in interface SolverType

setSolverParameters

public void setSolverParameters(String s)

Specified by:

setSolverParameters in interface SolverType

setSolverCommand

public void setSolverCommand(String s)

Specified by:

setSolverCommand in interface SolverType

getSolverCommand

public final String getSolverCommand()

Description copied from interface: SolverType

the command for starting the solver. For example "z3" if it is registered in the PATH variable, otherwise "ABSOLUTE_PATH/z3"

Specified by:

getSolverCommand in interface SolverType

getVersion

public String getVersion()

Description copied from interface: SolverType

Returns the current version that is installed, if it has already been checked, otherwise null.

Specified by:

getVersion in interface SolverType

getRawVersion

public String getRawVersion()

Description copied from interface: SolverType

Retrieve the version string without check for support. Returns null if the solver is not installed.

Specified by:

getRawVersion in interface SolverType

toString

public String toString()

Overrides:

toString in class Object

modifyProblem

public String modifyProblem(String problem)

Description copied from interface: SolverType

Directly before the problem description is sent to the solver one can modify the problem string by using this method.

Specified by:

modifyProblem in interface SolverType
