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

Class ComparisonExpression

java.lang.Object
io.atlasmap.expression.internal.BinaryExpression
org.qubership.integration.platform.engine.mapper.atlasmap.expressions.ComparisonExpression
All Implemented Interfaces:
io.atlasmap.expression.Expression, io.atlasmap.expression.internal.BooleanExpression
public abstract class ComparisonExpression extends io.atlasmap.expression.internal.BinaryExpression implements io.atlasmap.expression.internal.BooleanExpression
Copied from io.atlasmap.expression.internal.ComparisonExpression. Added support of comparison to null of complex objects. A filter performing a comparison of two objects.
