Method Detail

parseFile

public static void parseFile(KnowledgeBase kb,
                             File prologSourceFile)

Populates the KnowledgeBase with clauses defined in the file.

Parameters:

kb - the KnowledgeBase to add the clauses to

prologSourceFile - source of the prolog syntax defining clauses to add to the KnowledgeBase

Throws:

ProjogException - if there is any problem parsing the syntax or adding the new clauses to the KnowledgeBase

parseResource

public static void parseResource(KnowledgeBase kb,
                                 String prologSourceResourceName)

Populates the KnowledgeBase with clauses defined in the specified resource.

If prologSourceResourceName refers to an existing file on the file system then that file is used as the source of the prolog syntax else prologSourceResourceName is read from the classpath.

Parameters:

kb - the KnowledgeBase to add the clauses to

prologSourceResourceName - source of the prolog syntax defining clauses to add to the KnowledgeBase

Throws:

ProjogException - if there is any problem parsing the syntax or adding the new clauses to the KnowledgeBase

parseReader

public static void parseReader(KnowledgeBase kb,
                               Reader reader)

Populates the KnowledgeBase with clauses read from the Reader.

Note that this method will call close() on the specified reader - regardless of whether this method completes successfully or if an exception is thrown.

Parameters:

kb - the KnowledgeBase to add the clauses to

reader - source of the prolog syntax defining clauses to add to the KnowledgeBase

Throws:

ProjogException - if there is any problem parsing the syntax or adding the new clauses to the KnowledgeBase
