RowType (flink-cdc-common 3.3.0 API)

java.lang.Object
- org.apache.flink.cdc.common.types.DataType
- - org.apache.flink.cdc.common.types.RowType

所有已实现的接口:

Serializable
```
@PublicEvolving
public final class RowType
extends DataType
```
Data type of a sequence of fields. A field consists of a field name, field type, and an optional description. The most specific type of a record of a table is a record type. In this case, each column of the record corresponds to the field of the record type that has the same ordinal position as the column. Compared to the SQL standard, an optional field description simplifies the handling with complex structures.

方法详细资料
- getFields
```
public List<DataField> getFields()
```
- getFieldNames
```
public List<String> getFieldNames()
```
- getFieldTypes
```
public List<DataType> getFieldTypes()
```
- getTypeAt
```
public DataType getTypeAt(int i)
```
- getFieldCount
```
public int getFieldCount()
```
- getFieldIndex
```
public int getFieldIndex(String fieldName)
```
- copy
```
public DataType copy(boolean isNullable)
```
  从类复制的说明: DataType
  
  Returns a deep copy of this type with possibly different nullability.
  
  指定者:
  
  copy 在类中 DataType
  
  参数:
  
  isNullable - the intended nullability of the copied type
  
  返回:
  
  a deep copy
- asSummaryString
```
public String asSummaryString()
```
  从类复制的说明: DataType
  
  Returns a string that summarizes this type for printing to a console. An implementation might shorten long names or skips very specific properties.
  Use DataType.asSerializableString() for a type string that fully serializes this instance.
  
  覆盖:
  
  asSummaryString 在类中 DataType
  
  返回:
  
  summary string of this type for debugging purposes
- asSerializableString
```
public String asSerializableString()
```
  从类复制的说明: DataType
  
  Returns a string that fully serializes this instance. The serialized string can be used for transmitting or persisting a type.
  
  指定者:
  
  asSerializableString 在类中 DataType
  
  返回:
  
  detailed string for transmission or persistence
- getChildren
```
public List<DataType> getChildren()
```
  指定者:
  
  getChildren 在类中 DataType
- accept
```
public <R> R accept(DataTypeVisitor<R> visitor)
```
  指定者:
  
  accept 在类中 DataType
- equals
```
public boolean equals(Object o)
```
  覆盖:
  
  equals 在类中 DataType
- hashCode
```
public int hashCode()
```
  覆盖:
  
  hashCode 在类中 DataType
- of
```
public static RowType of(DataType... types)
