Package org.qubership.integration.platform.engine.mapper.atlasmap.expressions

Class CustomExpressionParser

java.lang.Object

org.qubership.integration.platform.engine.mapper.atlasmap.expressions.CustomExpressionParser

All Implemented Interfaces:

io.atlasmap.expression.parser.ParserConstants

public class CustomExpressionParser
extends Object
implements io.atlasmap.expression.parser.ParserConstants

Based on Atlasmap class Parser. Changed line in addExpression() to ArithmeticExpressionCustom.createCustomPlus(left, right). Since the original class is generated, when updating the atlasmap version, you need to pay attention to changes in original class
