```
public boolean isKey()
```
    Answers if the column part of the key
    
    Returns:
    true if the column is part of the key, else false
  - isNullable
```
public boolean isNullable()
```
    Answers if the column can be set to null
    
    Returns:
    true if it can be set to null, else false
  - getDefaultValue
```
public Object getDefaultValue()
```

    Returns:
    the default read value
  - getDesiredBlockSize
```
public int getDesiredBlockSize()
```
    Gets the desired block size for this column. If no block size has been explicitly specified for this column, returns 0 to indicate that the server-side default will be used.
    
    Returns:
    the block size, in bytes, or 0 if none has been configured.

```
public org.apache.kudu.ColumnSchema.Encoding getEncoding()
```
    Return the encoding of this column, or null if it is not known.
  - getCompressionAlgorithm
```
public org.apache.kudu.ColumnSchema.CompressionAlgorithm getCompressionAlgorithm()
```
    Return the compression algorithm of this column, or null if it is not known.
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
