类 BigDecimalTypeInfo

java.lang.Object

org.apache.flink.api.common.typeinfo.TypeInformation<T>

org.apache.flink.api.common.typeinfo.BasicTypeInfo<BigDecimal>

org.apache.flink.table.runtime.typeutils.BigDecimalTypeInfo

所有已实现的接口:

Serializable, org.apache.flink.api.common.typeinfo.AtomicType<BigDecimal>

public class BigDecimalTypeInfo
extends org.apache.flink.api.common.typeinfo.BasicTypeInfo<BigDecimal>

TypeInformation for BigDecimal.

It differs from BasicTypeInfo.BIG_DEC_TYPE_INFO in that: This type includes `precision` and `scale`, similar to SQL DECIMAL.
