Method Detail

visitEqualityExpr

public Filter visitEqualityExpr(OQLParser.EqualityExprContext ctx)

Description copied from class: OQLBaseVisitor

Visit a parse tree produced by the equalityExpr labeled alternative in OQLParser.expr().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitEqualityExpr in interface OQLVisitor<Filter>

Overrides:

visitEqualityExpr in class OQLFilterVisitor

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitComparisonExpr

public Filter visitComparisonExpr(OQLParser.ComparisonExprContext ctx)

Description copied from class: OQLBaseVisitor

Visit a parse tree produced by the comparisonExpr labeled alternative in OQLParser.expr().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitComparisonExpr in interface OQLVisitor<Filter>

Overrides:

visitComparisonExpr in class OQLFilterVisitor

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitInExpr

public Filter visitInExpr(OQLParser.InExprContext ctx)

Description copied from class: OQLBaseVisitor

Visit a parse tree produced by the inExpr labeled alternative in OQLParser.expr().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitInExpr in interface OQLVisitor<Filter>

Overrides:

visitInExpr in class OQLFilterVisitor

Parameters:

ctx - the parse tree

Returns:

the visitor result

getAttributes

public List<String> getAttributes()
