Package io.micronaut.expressions.parser.ast.operator.binary

Class RelationalOperator

java.lang.Object

io.micronaut.expressions.parser.ast.ExpressionNode

io.micronaut.expressions.parser.ast.operator.binary.RelationalOperator

@Internal
public final class RelationalOperator
extends ExpressionNode

Abstract expression AST node for relational operations. Relational operations can be applied to numeric types or types that are Comparable to each other. It is unclear at AST building stage what kind of relational operation will be performed, so this node does not directly include bytecode generation logic. At type resolution stage it instantiates either NumericComparisonOperation or ComparablesComparisonOperation and delegates bytecode generation to respective node instance.
