Method Details

visitQuery

public ASTNode visitQuery(RqlParser.QueryContext ctx)

Description copied from class: RqlBaseVisitor

Visit a parse tree produced by RqlParser.query().

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

Specified by:

visitQuery in interface RqlVisitor<ASTNode>

Overrides:

visitQuery in class RqlBaseVisitor<ASTNode>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitGroup

public ASTNode visitGroup(RqlParser.GroupContext ctx)

Description copied from class: RqlBaseVisitor

Visit a parse tree produced by the group labeled alternative in RqlParser.expression().

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

Specified by:

visitGroup in interface RqlVisitor<ASTNode>

Overrides:

visitGroup in class RqlBaseVisitor<ASTNode>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitLogical

public ASTNode visitLogical(RqlParser.LogicalContext ctx)

Description copied from class: RqlBaseVisitor

Visit a parse tree produced by the logical labeled alternative in RqlParser.expression().

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

Specified by:

visitLogical in interface RqlVisitor<ASTNode>

Overrides:

visitLogical in class RqlBaseVisitor<ASTNode>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitAnd

public ASTNode visitAnd(RqlParser.AndContext ctx)

Description copied from class: RqlBaseVisitor

Visit a parse tree produced by the and labeled alternative in RqlParser.expression().

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

Specified by:

visitAnd in interface RqlVisitor<ASTNode>

Overrides:

visitAnd in class RqlBaseVisitor<ASTNode>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitOr

public ASTNode visitOr(RqlParser.OrContext ctx)

Description copied from class: RqlBaseVisitor

Visit a parse tree produced by the or labeled alternative in RqlParser.expression().

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

Specified by:

visitOr in interface RqlVisitor<ASTNode>

Overrides:

visitOr in class RqlBaseVisitor<ASTNode>

Parameters:
