PngChunk.ChunkOrderingConstraint (PNGJ 2.0.1 API)

java.lang.Object
- java.lang.Enum<PngChunk.ChunkOrderingConstraint>
- - ar.com.hjg.pngj.chunks.PngChunk.ChunkOrderingConstraint

All Implemented Interfaces:

Serializable, Comparable<PngChunk.ChunkOrderingConstraint>

Enclosing class:

PngChunk
```
public static enum PngChunk.ChunkOrderingConstraint
extends Enum<PngChunk.ChunkOrderingConstraint>
```
Possible ordering constraint for a PngChunk type -only relevant for ancillary chunks. Theoretically, there could be more general constraints, but these cover the constraints for standard chunks.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`AFTER_PLTE_BEFORE_IDAT` Must go after PLTE (if exists) but before IDAT
`AFTER_PLTE_BEFORE_IDAT_PLTE_REQUIRED` Must go after PLTE (and it must exist) but before IDAT
`BEFORE_IDAT` Must before IDAT (before or after PLTE)
`BEFORE_PLTE_AND_IDAT` Must go before PLTE (and hence, also before IDAT)
`NA` Does not apply
`NONE` no ordering constraint

- Method Detail
  - values
```
public static PngChunk.ChunkOrderingConstraint[] 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 (PngChunk.ChunkOrderingConstraint c : PngChunk.ChunkOrderingConstraint.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static PngChunk.ChunkOrderingConstraint 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
  - mustGoBeforePLTE
