Class AnyUtil

java.lang.Object

eu.dnetlib.functionality.index.model.util.AnyUtil

Direct Known Subclasses:

AnySolrUtil

public class AnyUtil
extends Object

utility class for handling / conversion of Any objects. Hint: The Any-to-JSON conversion for Date(Time)s is not symmetric. If the Any object contains Date(Time) values, they will be serialized to String values in simple timestamp format. But when parsing JSON to an Any object, Date(Time) strings will not be recognized anymore, but just read as String values.

AnyUtil

protected AnyUtil()

prevent instance creation.

Method Detail

anyToNative

public static Object anyToNative(Any any)

Converts an Any object into a native java object.

Parameters:

any - the Any object

Returns:

a Pojo

objectToAny

public static Any objectToAny(Object object)

Converts an object to an Any (recursively). The leaf object(s) must be convertable by DataFactory.autoConvertValue(Object).

Parameters:

object - The object to be converted. Supported (and tested in this order) are

• Map<String, Object>
• Collections<Object>
• Object[]
• Any other object that can be DataFactory.autoConvertValue(Object)

Returns:

The converted Any

saveGet

public static Any saveGet(Any any,
                          String[] path)

get value for given path(list of keys) from AnyMap object. This methods throws no exception, if the path not exists an empty Any is the result.

Parameters:

any - the Any object.

path - path to the entry.

Returns:

value associated to the path.

exceptionToAny

public static AnyMap exceptionToAny(Throwable e)

convert an exception to an any object.

Parameters:

e - exception to convert

Returns:

any representation of exception

asDouble

public static Double asDouble(Any any)

null save version.

asBoolean

public static Boolean asBoolean(Any any)

null save version.

asDateTime

public static Date asDateTime(Any any)

null save version.

asDate

public static Date asDate(Any any)

null save version.

asLong

public static Long asLong(Any any)

null save version.

asString

public static String asString(Any any)

null save version.

asMap

public static AnyMap asMap(Any any)

null save version.

asSeq

public static AnySeq asSeq(Any any)

null save version.

anyToProperties

public static Properties anyToProperties(AnyMap anyMap)

convert AnyMap to java.util.Properties.

propertiesToAny

public static AnyMap propertiesToAny(Properties props)

convert java.util.Properties to AnyMap.

findMapInSeq

public static AnyMap findMapInSeq(AnySeq seq,
                                  String keyName,
                                  String keyValue)

returns the 1st map in the give SEQ that contains a value with the given name value, or null if not found. This is often useful for configs that are contained in a seq such as search filters.
