EcNumber (biojava-legacy 1.9.5 API)

All Known Implementing Classes:

EcNumber.Impl
```
public interface EcNumber
```
An ec (enzyme classification) number. Implementations of this interface should be imutable. This makes them much more usefull as keys in maps. it is a good idea to validate that the data being passed in is a sane ec number.

Since:

1.4

- Field Detail
  - EC_PATTERN
```
static final Pattern EC_PATTERN
```
    A Pattern that can be used to parse EC strings into the indiidual numbers.
  - UNDEFINED
```
static final int UNDEFINED
```
    Constant that represents EC number components that are not defined. This is often represented as a '-' in EC strings.

  - UNCLASSIFIED
```
static final int UNCLASSIFIED
```
    Constant that represents EC number components that are as yet unclassified. This is often represented as 99 in EC strings.

  - getClassNumber
```
int getClassNumber(int level)
```
    Get the class number associated with the particular level of the ec number.
    The index can be between 0 and 3 inclusive. 0 correxpons to the top level class, 1 to the sub-class and so on. A return value of UNDEFINED indicates that this field is not populated.
    
    Parameters:
    
    level - the level in the ec classification to return the number for
    
    Returns:
    
    the value at that level
