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<org.apache.iceberg.expressions.Expression,Void,RuntimeException>

Overrides:

visitUnknown in class AbstractExprVisitor<org.apache.iceberg.expressions.Expression,Void,RuntimeException>

Throws:

RuntimeException
