Method Detail

toIlmPositive

public static Long toIlmPositive(long value)

Transforms the designated long to Long. If the designated long is not positive (<=0), null will be returned.

Parameters:

value - The positive value which to transform to Long.

Returns:

The designated long value or null in case of 0 or a negative value.

toIlm

public static String toIlm(Serializable serialisable)
                    throws IOException

Serialises the designated value and Base64-encodes it.

Parameters:

serialisable - The value which to serialise and Base64-encode.

Returns:

The designated serialised value Base64-encoded.

Throws:

IOException - If serialising or encoding the designated serialisable fails, an IOException will be thrown.

toIlm

public static <K extends Comparable<? super K>,V> void toIlm(Map<K,V> map,
                                                                   Consumer<Map<K,V>> ilmField)

Makes a copy of the designated map and assigns it via the designated consumer to the corresponding field. The map entries will be sorted. If the map is null or empty, null will be assigned.

Type Parameters:

K - The type of the keys of the map.

V - The type of the values of the map.

Parameters:

map - The map which to copy or null.

ilmField - The consumer setting the copy of the map to the corresponding field.

toIlm

public static <K,V> void toIlm(Map<K,V> map,
                                     Comparator<? super K> comp,
                                     Consumer<Map<K,V>> ilmField)

Makes a copy of the designated map and assigns it via the designated consumer to the corresponding field. The map entries will be sorted using the designated comparator. If the map is null or empty, null will be assigned.

Type Parameters:

K - The type of the keys of the map.

V - The type of the values of the map.

Parameters:

map - The map which to copy or null.

comp - The comparator for sorting (the keys of) the map entry.

ilmField - The consumer setting the copy of the map to the corresponding field.

toIlm

public static ParameterException toIlm(de.aristaflow.adept2.model.communication.webservice.ParameterException pe)

Transforms the designated de.aristaflow.adept2.model.communication.webservice.ParameterException to the corresponding (subclass of) de.aristaflow.ilm.utilParameterException.

Parameters:

pe - The de.aristaflow.adept2.model.communication.webservice.ParameterException which to transform to the corresponding (subclass of) de.aristaflow.ilm.utilParameterException.

Returns:

The (subclass of) de.aristaflow.ilm.utilParameterException corresponding to the designated de.aristaflow.adept2.model.communication.webservice.ParameterException.

toIlm

public static Map<String,String> toIlm(org.apache.commons.configuration2.Configuration conf)

Transforms the designated configuration to a string map. The elements of the configuration will simply be transformed to a string using Object.toString().

Parameters:

conf - The configuration which to transform to a string map. This may be null.

Returns:

A string map containing the entries of the designated configuration or null in case the configuration is null or empty.

fromIlmNull

public static boolean fromIlmNull(Boolean value)

Transforms the designated Boolean to a simple boolean. If the designated Boolean is null, false will be returned.

Parameters:

value - The value which to transform to boolean.

Returns:

The designated boolean value or false in case of null.

fromIlmNull

public static int fromIlmNull(Integer value)

Transforms the designated Integer to a simple int. If the designated Integer is null, 0 will be returned.

Parameters:

value - The value which to transform to int.

Returns:

The designated int value or 0 in case of null.

fromIlmNull

public static int fromIlmNull(Integer value,
                              int nullValue)

Transforms the designated Long to a simple long. If the designated Long is null, the designated nullValue will be returned.

Parameters:

value - The value which to transform to long.

nullValue - The value to use in case the designated value is null.

Returns:

The designated long value or the designated nullValue in case of null.

fromIlmNull

public static long fromIlmNull(Long value)

Transforms the designated Long to a simple long. If the designated Long is null, 0 will be returned.

Parameters:

value - The value which to transform to long.

Returns:

The designated long value or 0 in case of null.

fromIlmNull

public static long fromIlmNull(Long value,
                               long nullValue)

Transforms the designated Long to a simple long. If the designated Long is null, the designated nullValue will be returned.

Parameters:

value - The value which to transform to long.

nullValue - The value to use in case the designated value is null.

Returns:

The designated long value or the designated nullValue in case of null.

fromIlm

public static <T extends Throwable> T fromIlm(IlmException ilm,
                                              T af)

Takes over the stack trace and the cause (if available) from the designated ilm exception to the designated throwable.

Parameters:

ilm - The ilm exception that occurred.

af - The throwable to be thrown into a service.

Returns:

The throwable to be thrown into a service having the stack trace and the cause from the designated ilm exception (if available).

toIlm

public static IlmException toIlm(Throwable t)

Creates a new IlmException that is closest to the designated throwable. This is either a subclass of IlmException corresponding to the designated throwable or a WrappingException for a throwable that has no corresponding ILM exception.

Parameters:

t - The throwable which to convert to an ILM exception.

Returns:

The ILM exception that corresponds to the designated throwable or a WrappingException.
