Method Detail

getValues
public abstract java.lang.String[] getValues()
This is the only method a subclass needs to implement.- Returns:
- 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 BuildException
Factory 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:
- https://issues.apache.org/bugzilla/show_bug.cgi?id=14831
-
setValue
public void setValue(java.lang.String value) throws BuildException
Invoked byIntrospectionHelper
.- Parameters:
value
- theString
value of the attribute- Throws:
BuildException
- if the value is not valid for the attribute
-
containsValue
public final boolean containsValue(java.lang.String value)
Is this value included in the enumeration?- Parameters:
value
- theString
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:
value

- the index of the value in the array of strings or -1 if it cannot be found.
- See Also:
getValues()
-
getValue
public final java.lang.String getValue()
- Returns:
- the selected value.
-
getIndex
public final int getIndex()
- Returns:
- the index of the selected value in the array.
- See Also:
getValues()
-
toString
public java.lang.String toString()
