Class Ek9SourceVisitor

java.lang.Object

org.antlr.v4.runtime.tree.AbstractParseTreeVisitor<Void>

org.ek9lang.antlr.EK9BaseVisitor<Void>

org.ek9lang.compiler.common.Ek9SourceVisitor

All Implemented Interfaces:

org.antlr.v4.runtime.tree.ParseTreeVisitor<Void>, EK9Visitor<Void>

public class Ek9SourceVisitor
extends EK9BaseVisitor<Void>

A cut down visitor that just deals with packages at a basic level. Now refactored the results of the visit out to an immutable record, so the private properties in this visitor are now transient.

Constructor Details

Ek9SourceVisitor

public Ek9SourceVisitor()

Method Details

visit

public void visit(EK9Parser.CompilationUnitContext context,
 ErrorListener errorListener)

This is the key to lexing and parsing the source file mainly just for package information.

getPackageDetails

public Optional<PackageDetails> getPackageDetails()

visitModuleDeclaration

public Void visitModuleDeclaration(EK9Parser.ModuleDeclarationContext ctx)

Description copied from class: EK9BaseVisitor

Visit a parse tree produced by EK9Parser.moduleDeclaration().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(RuleNode) on ctx.

Specified by:

visitModuleDeclaration in interface EK9Visitor<Void>

Overrides:

visitModuleDeclaration in class EK9BaseVisitor<Void>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitProgramBlock

public Void visitProgramBlock(EK9Parser.ProgramBlockContext ctx)

Description copied from class: EK9BaseVisitor

Visit a parse tree produced by EK9Parser.programBlock().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(RuleNode) on ctx.

Specified by:

visitProgramBlock in interface EK9Visitor<Void>

Overrides:

visitProgramBlock in class EK9BaseVisitor<Void>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitPackageBlock

public Void visitPackageBlock(EK9Parser.PackageBlockContext ctx)

Description copied from class: EK9BaseVisitor

Visit a parse tree produced by EK9Parser.packageBlock().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(RuleNode) on ctx.

Specified by:

visitPackageBlock in interface EK9Visitor<Void>

Overrides:

visitPackageBlock in class EK9BaseVisitor<Void>

Parameters:

ctx - the parse tree

Returns:

the visitor result
