ODocumentHelper

public ODocumentHelper()

Method Details

getReservedAttributes

public static Set<String> getReservedAttributes()

sort

public static void sort(List<? extends OIdentifiable> ioResultSet,
 List<OPair<String,String>> iOrderCriteria,
 OCommandContext context)

convertField

public static <RET> RET convertField(ODocument iDocument,
 String iFieldName,
 OType type,
 Class<?> iFieldType,
 Object iValue)

getFieldValue

public static <RET> RET getFieldValue(Object value,
 String iFieldName)

getFieldValue

public static <RET> RET getFieldValue(Object value,
 String iFieldName,
 OCommandContext iContext)

getIndexPart

protected static Object getIndexPart(OCommandContext iContext,
 String indexPart)

filterItem

protected static Object filterItem(String iConditionFieldName,
 Object iConditionFieldValue,
 Object iValue)

getMapEntry

public static Object getMapEntry(Map<String,?> iMap,
 Object iKey)

Retrieves the value crossing the map with the dotted notation

Parameters:

iMap -

iKey - Field(s) to retrieve. If are multiple fields, then the dot must be used as separator

Returns:

getIdentifiableValue

public static Object getIdentifiableValue(OIdentifiable iCurrent,
 String iFieldName)

evaluateFunction

public static Object evaluateFunction(Object currentValue,
 String iFunction,
 OCommandContext iContext)

cloneValue

public static Object cloneValue(ODocument iCloned,
 Object fieldValue)

hasSameContentItem

public static boolean hasSameContentItem(Object iCurrent,
 ODatabaseDocumentInternal iMyDb,
 Object iOther,
 ODatabaseDocumentInternal iOtherDb,
 ODocumentHelper.RIDMapper ridMapper)

hasSameContentOf

public static boolean hasSameContentOf(ODocument iCurrent,
 ODatabaseDocumentInternal iMyDb,
 ODocument iOther,
 ODatabaseDocumentInternal iOtherDb,
 ODocumentHelper.RIDMapper ridMapper)

Makes a deep comparison field by field to check if the passed ODocument instance is identical as identity and content to the current one. Instead equals() just checks if the RID are the same.

Parameters:

iOther - ODocument instance

Returns:

true if the two document are identical, otherwise false

See Also:

• Object.equals(Object)

hasSameContentOf

public static boolean hasSameContentOf(ODocument iCurrent,
 ODatabaseDocumentInternal iMyDb,
 ODocument iOther,
 ODatabaseDocumentInternal iOtherDb,
 ODocumentHelper.RIDMapper ridMapper,
 boolean iCheckAlsoIdentity)

Makes a deep comparison field by field to check if the passed ODocument instance is identical in the content to the current one. Instead equals() just checks if the RID are the same.

Parameters:

iOther - ODocument instance

Returns:

true if the two document are identical, otherwise false

See Also:

• Object.equals(Object)

public static boolean compareCollections(ODatabaseDocumentInternal iMyDb,
 Collection<?> myFieldValue,
 ODatabaseDocumentInternal iOtherDb,
 Collection<?> otherFieldValue,
 ODocumentHelper.RIDMapper ridMapper)
