visitProperty_values

public Map<String,String> visitProperty_values(SchemaParser.Property_valuesContext ctx)

Description copied from class: SchemaParserBaseVisitor

Visit a parse tree produced by SchemaParser.property_values().

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

Specified by:

visitProperty_values in interface SchemaParserVisitor<Map<String,String>>

Overrides:

visitProperty_values in class SchemaParserBaseVisitor<Map<String,String>>

Parameters:

ctx - the parse tree

Returns:

the visitor result
