Method Summary

Modifier and Type	Method and Description
String[]	alternativePrologExtensions(String filename)
String	executablePath(String d) This returns the same path d if it ends in ...bin
String	getBinDirectoryEnvVar()
boolean	hasPrologExtension(String filename)
String	interprologFilename() Returns the path for the Prolog file that must be loaded for InterProlog to function, USING '/' AS THE SEPARATION CHARACTER independently of the OS platform
boolean	isInterrupt(Object error) True if an error, as obtained in a ResultFromProlog object, looks like an interrupt detection on the Prolog side, cf.
Recognizer	makeBreakRecognizer()
Recognizer	makePromptRecognizer()
String	prologBinToBaseDirectory(String binDirectoryOrStartCommand) Assumes that Prolog options can not include "/bin/"...
String	unescapedFilePath(String p) Some Prologs use '\' as an escape character in atoms, which can affect file paths under Windows.
String	visualizationFilename() Returns the path for the Prolog file that must be loaded for InterProlog's visualization predicates to function, typically in the context of using a ListenerWindow.

Method Detail

getBinDirectoryEnvVar

public String getBinDirectoryEnvVar()

Specified by:

getBinDirectoryEnvVar in class PrologImplementationPeer

executablePath

public String executablePath(String d)

This returns the same path d if it ends in ...bin

Specified by:

executablePath in class PrologImplementationPeer

alternativePrologExtensions

public String[] alternativePrologExtensions(String filename)

Specified by:

alternativePrologExtensions in class PrologImplementationPeer

hasPrologExtension

public boolean hasPrologExtension(String filename)

Overrides:

hasPrologExtension in class PrologImplementationPeer

prologBinToBaseDirectory

public String prologBinToBaseDirectory(String binDirectoryOrStartCommand)

Assumes that Prolog options can not include "/bin/"...

Specified by:

prologBinToBaseDirectory in class PrologImplementationPeer

makePromptRecognizer

public Recognizer makePromptRecognizer()

Specified by:

makePromptRecognizer in class PrologImplementationPeer

makeBreakRecognizer

public Recognizer makeBreakRecognizer()

Specified by:

makeBreakRecognizer in class PrologImplementationPeer

interprologFilename

public String interprologFilename()

Description copied from class: PrologImplementationPeer

Returns the path for the Prolog file that must be loaded for InterProlog to function, USING '/' AS THE SEPARATION CHARACTER independently of the OS platform

Specified by:

interprologFilename in class PrologImplementationPeer

visualizationFilename

public String visualizationFilename()

Description copied from class: PrologImplementationPeer

Returns the path for the Prolog file that must be loaded for InterProlog's visualization predicates to function, typically in the context of using a ListenerWindow. Although the file is common for all Prologs, some (eg XSB) have a compiled form, others do not

Specified by:

visualizationFilename in class PrologImplementationPeer

isInterrupt

public boolean isInterrupt(Object error)

Description copied from class: PrologImplementationPeer

True if an error, as obtained in a ResultFromProlog object, looks like an interrupt detection on the Prolog side, cf. predicate handleDeterministicGoal in interprolog.P/pl/etc. resultError is not null

Specified by:

isInterrupt in class PrologImplementationPeer

unescapedFilePath

public String unescapedFilePath(String p)

Description copied from class: PrologImplementationPeer

Some Prologs use '\' as an escape character in atoms, which can affect file paths under Windows. Use this method to preprocess all file paths passed to Prolog. this default implementation does no preprocessing, subclasses should define their own if needed

Overrides:

unescapedFilePath in class PrologImplementationPeer
