Constructors¶

AMPLProcess¶

protected AMPLProcess(Environment env, Engine engine)¶

Methods¶

canInterrupt¶

public boolean canInterrupt()¶

close¶

public void close()¶: Stops the process.

create¶

public static AMPLProcess create(Environment env, Engine engine)¶: Starts an AMPL process (class factory, generates process which is platform dependent)

createProcessBuilder¶

protected ProcessBuilder createProcessBuilder()¶

getAMPLVersion¶

int getAMPLVersion()¶

Returns the ampl version as an integer, getting it from the underlying AMPL interpreter

Parameters:	amplPath – Path to ampl executable env – Environment
Throws:	ReadException – IOException –
Returns:	AMPL version. If OptiRisk AMPL, the returned integer is negative. So (version <0) returns true if it is an OptiRisk AMPL (it embeds AMPLSIG in windows versions) and abs(version) returns the actual version number

getVersion¶

int getVersion()¶: Get stored AMPL version

getWorkingDir¶

public String getWorkingDir()¶

interpretAndReturn¶

void interpretAndReturn(String s, OutputHandler output)¶

interpretAndReturn¶

AMPLOutputs interpretAndReturn(String s)¶

interpretAsync¶

void interpretAsync(String s, Runnable over, OutputHandler output)¶

interrupt¶

public void interrupt()¶

isBusy¶

public boolean isBusy()¶: Returns true if the engine is busy in an async operation

isProcessRunning¶

public Boolean isProcessRunning()¶

isStarted¶

public boolean isStarted()¶

onBeginSolve¶

public void onBeginSolve()¶

onInterrupt¶

protected void onInterrupt()¶: When the underlying process is interrupted, need to wait for the reader thread to finish or else we end up with a dirty buffer

setWorkingDir¶

public void setWorkingDir(String workingdir)¶

start¶

public void start()¶: Starts the underlying process
