adapt

public static java.util.Map<java.lang.String,java.lang.String> adapt(java.util.Map<java.lang.String,java.lang.String[]> adapted)

Adapt a Map map as a Map map. The adapted map must not contain null string array or zero lenght string array, if the map contains such values then the map state is considered as not valid and IllegalStateException can be thrown when the adapted map

is used.

The adapted map is writable but does not accept null values for write operations. On a put operation the adapted map will receive a put operation with a string array of length one containing the provided value.

Parameters:

adapted - the adapted map

Returns:

the adapter
