- Field Detail
  - type
```
public Type type
```
    Data type for this field. Not set if the current element is a non-leaf node
    
    See Also:
    
    Type
  - type_length
```
public int type_length
```
    If type is FIXED_LEN_BYTE_ARRAY, this is the byte length of the vales. Otherwise, if specified, this is the maximum bit length to store any of the values. (e.g. a low cardinality INT col could have this set to 3). Note that this is in the schema, and therefore fixed for the entire file.
  - repetition_type
```
public FieldRepetitionType repetition_type
```
    repetition of the field. The root of the schema does not have a repetition_type. All other nodes must have one
    
    See Also:

  - name
```
public String name
```
    Name of the field in the schema
  - num_children
```
public int num_children
```
    Nested fields. Since thrift does not support nested fields, the nesting is flattened to a single list by a depth-first traversal. The children count is used to construct the nested relationship. This field is not set when the element is a primitive type
  - converted_type
```
public ConvertedType converted_type
```
    DEPRECATED: When the schema is the result of a conversion from another model. Used to record the original type to help with cross conversion. This is superseded by logicalType.
    
    See Also:
    
    ConvertedType
  - scale
```
public int scale
```
    DEPRECATED: Used when this column contains decimal data. See the DECIMAL converted type for more details. This is superseded by using the DecimalType annotation in logicalType.
  - precision
```

```
    When the original schema supports field ids, this will save the original field id in the parquet schema

```
    The logical type of this SchemaElement LogicalType replaces ConvertedType, but ConvertedType is still required for some logical types to ensure forward-compatibility in format v1.
