Example 1 with TypeSignatureKeyDeserializer

use of io.trino.type.TypeSignatureKeyDeserializer in project trino by trinodb.

the class TestPatternRecognitionNodeSerialization method testPatternRecognitionNodeRoundtrip.

@Test
public void testPatternRecognitionNodeRoundtrip() {
    ObjectMapperProvider provider = new ObjectMapperProvider();
    provider.setJsonSerializers(ImmutableMap.of(Expression.class, new ExpressionSerialization.ExpressionSerializer()));
    provider.setJsonDeserializers(ImmutableMap.of(Expression.class, new ExpressionSerialization.ExpressionDeserializer(new SqlParser()), Type.class, new TypeDeserializer(TESTING_TYPE_MANAGER)));
