                                    Void value)
                             throws RuntimeException

Specified by:

visitSchemaPath in interface ExprVisitor<JsonScanSpec,Void,RuntimeException>

Overrides:

Throws:

RuntimeException

visitUnknown

public JsonScanSpec visitUnknown(LogicalExpression e,
                                 Void value)
                          throws RuntimeException

Description copied from class: AbstractExprVisitor

Handles implementation-specific expressions not known to the visitor structure. Since there are no "visitFoo" methods for these "unknown" expressions, subclassses should use the functionally-equivalent instanceof approach to parse out these "unknown" expressions.

Specified by:

visitUnknown in interface ExprVisitor<JsonScanSpec,Void,RuntimeException>

Overrides:

visitUnknown in class AbstractExprVisitor<JsonScanSpec,Void,RuntimeException>

Throws:

RuntimeException

Specified by:

visitBooleanOperator in interface ExprVisitor<JsonScanSpec,Void,RuntimeException>

Overrides:
