Fields in org.apache.hudi.expression with type parameters of type Expression

Modifier and Type	Field and Description
protected List<Expression>	Predicates.In.validValues

Methods in org.apache.hudi.expression that return Expression

Modifier and Type	Method and Description
Expression	BindVisitor.alwaysFalse()
Expression	BindVisitor.alwaysTrue()
Expression	BinaryExpression.getLeft()
Expression	BinaryExpression.getRight()
Expression	BindVisitor.visitAnd(Predicates.And and)
Expression	BindVisitor.visitBoundReference(BoundReference boundReference)
Expression	BindVisitor.visitLiteral(Literal literal)
Expression	BindVisitor.visitNameReference(NameReference attribute)
Expression	PartialBindVisitor.visitNameReference(NameReference attribute) If the attribute cannot find from the schema, directly return null, visitPredicate will handle it.
Expression	BindVisitor.visitOr(Predicates.Or or)
Expression	BindVisitor.visitPredicate(Predicate predicate)
Expression	PartialBindVisitor.visitPredicate(Predicate predicate) If an expression is null after accept method, which means it cannot be bounded from schema, we'll directly return Predicates.TrueExpression.
