Package io.substrait.expression

Interface Expression.UserDefinedLiteral

All Superinterfaces:

Expression, Expression.Literal, FunctionArg

All Known Implementing Classes:

Expression.UserDefinedAnyLiteral, Expression.UserDefinedStructLiteral, ImmutableExpression.UserDefinedAnyLiteral, ImmutableExpression.UserDefinedStructLiteral

Enclosing interface:

Expression

public static interface Expression.UserDefinedLiteral
extends Expression.Literal

Base interface for user-defined literals.

User-defined literals can be encoded in one of two ways as per the Substrait spec:

• As google.protobuf.Any - see Expression.UserDefinedAnyLiteral
• As Literal.Struct - see Expression.UserDefinedStructLiteral
