- an array holding all possible values of the enumeration.
The order of elements must be fixed so that
indexOfValue(String)
always return the same index for the same value.
-
getInstance
public static EnumeratedAttribute getInstance(java.lang.Class<? extends EnumeratedAttribute> clazz, java.lang.String value) throws BuildExceptionFactory method for instantiating EAs via API in a more developer friendly way.- Parameters:
clazz
- Class, extending EA, which to instantiatevalue
- The value to set on that EA- Returns:
- Configured EA
- Throws:
BuildException
- If the class could not be found or the value is not valid for the given EA-class.- See Also:

value to look up- Returns:
- true if the value is valid
-
indexOfValue
public final int indexOfValue(java.lang.String value)get the index of a value in this enumeration.- Parameters:
