Enum Constant Detail- 
CSVpublic static final FrameFormat CSV Comma-separated value format (dense).
 - 
IJVpublic static final FrameFormat IJV (I J V) format (sparse). I and J represent frame coordinates and V represents the value. The I J and V values are space-separated.
 - 
DFpublic static final FrameFormat DF DataFrame without a row index.
 - 
DF_WITH_INDEXpublic static final FrameFormat DF_WITH_INDEX DataFrame with a row index.

Method Detail- 
valuespublic static FrameFormat[] 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 (FrameFormat c : FrameFormat.values()) System.out.println(c); - Returns:
- an array containing the constants of this enum type, in the order they are declared
 
 - 
valueOfpublic static FrameFormat 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
