Class SWRLParser

java.lang.Object

org.swrlapi.parser.SWRLParser

public class SWRLParser
extends java.lang.Object

A basic SWRL and SQWRL parser. It provides an interactive parsing mode for incomplete rules and queries and provides feedback on the next token that it is expecting.

This parser will throw a SWRLParseException if there is an error in the rule or query. In interactive parse mode, if the rule or query is correct but incomplete a SWRLIncompleteRuleException (which is a subclass of SWRLParseException) will be thrown.

The parseSWRLRule(String, boolean, String, String) method parses a rule or query. If interactiveParseOnly argument is true, only checking is performed - no SWRL rules are created; if it is false, a SWRLRule object is created.

The parser does not yet parse OWL class expressions and only supports a basic form of data range atoms.

Parameters:

ruleText - The rule text

interactiveParseOnly - If True simply parse

ruleName - The rule name

comment - A comment

Returns:

The parsed rule

Throws:

SWRLParseException - If an error occurs during parsing

isSWRLRuleCorrectButPossiblyIncomplete

public boolean isSWRLRuleCorrectButPossiblyIncomplete(@NonNull java.lang.String ruleText)

If the rule is correct though possibly incomplete return true; if the rule has errors return false.

Parameters:

ruleText - The rule text

Returns:

True if the rule is valid but possibly incomplete

isSWRLRuleCorrectAndComplete

public boolean isSWRLRuleCorrectAndComplete(@NonNull java.lang.String ruleText)

If the rule is correct and complete return true; if the rule has errors or is incomplete return false.

Parameters:

ruleText - The rule text

Returns:

True is the rule is correct and complete
