visitColumn_def

public ColumnMetadata visitColumn_def(SchemaParser.Column_defContext ctx)

Description copied from class: SchemaParserBaseVisitor

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

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

Specified by:

visitColumn_def in interface SchemaParserVisitor<ColumnMetadata>

Overrides:

visitColumn_def in class SchemaParserBaseVisitor<ColumnMetadata>

Parameters:

ctx - the parse tree

Returns:

the visitor result
