long fileSizeInBytes()
```
    Returns:
    
    the data file size in bytes
  - blockSizeInBytes
```
long blockSizeInBytes()
```
    Returns:
    
    the data file block size in bytes (for split planning)
  - fileOrdinal
```
java.lang.Integer fileOrdinal()
```
    Returns:
    
    file ordinal if written in a global ordering, or null
  - sortColumns
```
java.util.List<java.lang.Integer> sortColumns()
```
    Returns:
    
    list of columns the file records are sorted by, or null
  - columnSizes
```
java.util.Map<java.lang.Integer,java.lang.Long> columnSizes()
```
    Returns:
    
    if collected, map from column ID to the size of the column in bytes, null otherwise
  - valueCounts
```
java.util.Map<java.lang.Integer,java.lang.Long> valueCounts()
```
    Returns:
    
    if collected, map from column ID to the count of its non-null values, null otherwise
  - nullValueCounts
```
java.util.Map<java.lang.Integer,java.lang.Long> nullValueCounts()
```
    Returns:
    
    if collected, map from column ID to its null value count, null otherwise
  - lowerBounds
```
java.util.Map<java.lang.Integer,java.nio.ByteBuffer> lowerBounds()
```
    Returns:
    
    if collected, map from column ID to value lower bounds, null otherwise
  - upperBounds
```
java.util.Map<java.lang.Integer,java.nio.ByteBuffer> upperBounds()
```
    Returns:
    
    if collected, map from column ID to value upper bounds, null otherwise
  - copy
```
DataFile copy()
```
    Copies this data file. Manifest readers can reuse data file instances; use this method to copy data when collecting files from tasks.
    
    Returns:
    
    a copy of this data file
