Constructor Summary

EntityUtils()

Method Summary

static boolean	contains(Collection<org.ofbiz.core.entity.GenericValue> entities, org.ofbiz.core.entity.GenericValue entity) Checks if a collection of entities contains an identical entity to the one provided.
static org.ofbiz.core.entity.GenericValue	createValue(String entity, Map<String,?> paramMap) Create a new entity.
static List<org.ofbiz.core.entity.GenericValue>	filterByAnd(List<org.ofbiz.core.entity.GenericValue> values, List<? extends org.ofbiz.core.entity.EntityExpr> exprs) This method is analogous to the OFBiz EntityUtil.filterByAnd method except that theirs does not filter on GT, GTE, LT, LTE yet.
static String	getNextStringId(String entityName) Calculate a new entity ID (by basically taking one more than the max integer that exists).
static org.ofbiz.core.entity.EntityOperator	getOperator(String code) Small utility method to get an entity operator from it's code
static boolean	identical(org.ofbiz.core.entity.GenericValue v1, org.ofbiz.core.entity.GenericValue v2) Compare two GenericValues based on their content.

Method Detail

getOperator

public static org.ofbiz.core.entity.EntityOperator getOperator(String code)

Small utility method to get an entity operator from it's code

createValue

public static org.ofbiz.core.entity.GenericValue createValue(String entity,
                                                             Map<String,?> paramMap)
                                                      throws org.ofbiz.core.entity.GenericEntityException

Create a new entity. If there is no "id" in the parameter list, one is created using the entity sequence

Throws:

org.ofbiz.core.entity.GenericEntityException

identical

public static boolean identical(org.ofbiz.core.entity.GenericValue v1,
                                org.ofbiz.core.entity.GenericValue v2)

Compare two GenericValues based on their content. This method will check the keys and values of both GenericValues. There is only a single difference between this method and GenericValue.equals(gv2), that is that if one GV has no key of a certain type, and the other has a null value for that key, they are still deemed to be identical (as GenericValue.get(key) always returns null if the key exists or not).

Returns:

true if the issues are the same, false if they are different

contains

public static boolean contains(Collection<org.ofbiz.core.entity.GenericValue> entities,
                               org.ofbiz.core.entity.GenericValue entity)

Checks if a collection of entities contains an identical entity to the one provided.

Parameters:

entities - The list of entities to search

entity - The entity to search for and compare to

Returns:

The matching entity, or null if no matching entity is found

filterByAnd

public static List<org.ofbiz.core.entity.GenericValue> filterByAnd(List<org.ofbiz.core.entity.GenericValue> values,
                                                                   List<? extends org.ofbiz.core.entity.EntityExpr> exprs)

This method is analogous to the OFBiz EntityUtil.filterByAnd method except that theirs does not filter on GT, GTE, LT, LTE yet.

Parameters:

values - A collection of GenericValues

exprs - The expressions that must validate to true

Returns:

Collection of GenericValues that match the expression list

getNextStringId

public static String getNextStringId(String entityName)
                              throws org.ofbiz.core.entity.GenericEntityException

Calculate a new entity ID (by basically taking one more than the max integer that exists). If there are string IDs here, they will not be affected.

Throws:

org.ofbiz.core.entity.GenericEntityException
