All Known Implementing Classes:

EcNumber.Impl

public interface EcNumber

An ec (enzyme classification) number.

Since:

1.4

Author:

For developers:

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.

Nested Class Summary

static class

EcNumber.Impl A simple implementation of EcNumber.

Field Summary

static Pattern	EC_PATTERN A Pattern that can be used to parse EC strings into the indiidual numbers.
static int	UNCLASSIFIED Constant that represents EC number components that are as yet unclassified.
static int	UNDEFINED Constant that represents EC number components that are not defined.

Method Summary

int	getClassNumber(int level) Get the class number associated with the particular level of the ec number.

Field Detail

EC_PATTERN

public static final Pattern EC_PATTERN

A Pattern that can be used to parse EC strings into the indiidual numbers.

UNDEFINED

public static final int UNDEFINED

Constant that represents EC number components that are not defined. This is often represented as a '-' in EC strings.

UNCLASSIFIED

public static final int UNCLASSIFIED

Constant that represents EC number components that are as yet unclassified. This is often represented as 99 in EC strings.

Method Detail

getClassNumber

public 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
