- Enum Constant Detail
  - FILE_PATH
```
public static final ColumnChunk._Fields FILE_PATH
```
    File where column data is stored. If not set, assumed to be same file as metadata. This path is relative to the current file.
  - FILE_OFFSET
```
public static final ColumnChunk._Fields FILE_OFFSET
```
    Byte offset in file_path to the ColumnMetaData *
  - META_DATA
```
public static final ColumnChunk._Fields META_DATA
```
    Column metadata for this chunk. This is the same content as what is at file_path/file_offset. Having it here has it replicated in the file metadata.
  - OFFSET_INDEX_OFFSET
```
public static final ColumnChunk._Fields OFFSET_INDEX_OFFSET
```
    File offset of ColumnChunk's OffsetIndex *
  - OFFSET_INDEX_LENGTH
```
public static final ColumnChunk._Fields OFFSET_INDEX_LENGTH
```
    Size of ColumnChunk's OffsetIndex, in bytes *
  - COLUMN_INDEX_OFFSET
```
public static final ColumnChunk._Fields COLUMN_INDEX_OFFSET
```

  - COLUMN_INDEX_LENGTH
```
public static final ColumnChunk._Fields COLUMN_INDEX_LENGTH
```
    Size of ColumnChunk's ColumnIndex, in bytes *
  - CRYPTO_METADATA
```
public static final ColumnChunk._Fields CRYPTO_METADATA
```
    Crypto metadata of encrypted columns *
  - ENCRYPTED_COLUMN_METADATA

- Method Detail
  - values
```
public static ColumnChunk._Fields[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (ColumnChunk._Fields c : ColumnChunk._Fields.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ColumnChunk._Fields valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - findByThriftId
```
public static ColumnChunk._Fields findByThriftId(int fieldId)
```
    Find the _Fields constant that matches fieldId, or null if its not found.
  - findByThriftIdOrThrow
```
public static ColumnChunk._Fields findByThriftIdOrThrow(int fieldId)
```
    Find the _Fields constant that matches fieldId, throwing an exception if it is not found.
  - findByName
```
public static ColumnChunk._Fields findByName(String name)
```
    Find the _Fields constant that matches name, or null if its not found.
  - getThriftFieldId
```
public short getThriftFieldId()
```
    Specified by:
    
    getThriftFieldId in interface org.apache.thrift.TFieldIdEnum
  - getFieldName
```
public String getFieldName()
```
    Specified by:
    
    getFieldName in interface org.apache.thrift.TFieldIdEnum
