getEnums

public static <TYPE extends ValueEnum> TYPE[] getEnums(TYPE[] enums,
                                                       String[] values,

Get a enum items by values.

The java 1.6 does not support a code " (TYPE[]) new Object[values.length];". Also, the GWT does not support a reflection api ( {@link java.lang.reflect.Array#newInstance}). So you need to pass an array argument to store the result.

Parameters:

enums - - enum items

values - - enum values

result - - array to store the result

Returns:

enum items

public static <TYPE extends ValueEnum> ValueEnum[] getEnums(TYPE[] enums,
                                                            String[] values)

Deprecated. use {getEnums(ValueEnum[], String[], ValueEnum[]) method

Get a enum items by values.

This method is not compatible with the java 1.6.

Parameters:

enums - - enum items

values - - enum values

Returns:

enum items
