Class StructuredParser

java.lang.Object

com.singularsys.jep.configurableparser.ConfigurableParser

com.singularsys.extensions.structure.StructuredParser

All Implemented Interfaces:

JepComponent, Parser, java.io.Serializable

Direct Known Subclasses:

ExtDocsTest.MyStructuredParser, StandardStructuredParser

public class StructuredParser
extends ConfigurableParser

Base class for defining a parser for structured code.

The class can either be used by subclassing and setting the configuration of the parser in the constructor or by creating a StructuredParser object and calling its configuration methods.

public class StandardStructuredParser extends StructuredParser {
    public StandardStructuredParser() {
        super();

        this.addHashComments();
        ...
        ExpressionRule expr = new ExpressionRule();
        StatementRule statement = new StatementRule();
        SequenceRule seq = new SequenceRule(statement);
        ....
        setStructuredRules(seq,expr);
    }
}
 

or

   StructuredParser parser = new StructuredParser();
   parser.addHashComments();
   ...
   ExpressionRule expr = new ExpressionRule();
   StatementRule statement = new StatementRule();
   SequenceRule seq = new SequenceRule(statement);
   ....
   parser.setStructuredRules(seq,expr);
