HelperContext

TypeHelper - Access Metadata

TypeHelper provides a convenient means of handling SDO metadata.

TypeHelper typeHelper = helperContext.getTypeHelper();

XSDHelper - Access XML Schema Metadata

XSDHelper provides a convenient means of handling XML Schema metadata.

XSDHelper xsdHelper = helperContext.getXSDHelper();

DataFactory - Create DataObjects

DataFactory provides a convenient means of creating SDO DataObjects.

DataFactory dataFactory = helperContext.getDataFactory();

DataHelper - Convert Simple Values

DataHelper provides a convenient means of converting SDO data type values.

DataHelper dataHelper = helperContext.getDataHelper();

XMLHelper - Handle XML Data as DataObjects

XMLHelper provides a convenient means of handling XML data as DataObjects.

XMLHelper xmlHelper = helperContext.getXMLHelper();

CopyHelper - Create Copies of DataObjects

CopyHelper provides a convenient means of copying DataObjects.

CopyHelper copyHelper = helperContext.getCopyHelper();

Shallow Copy

Create a new DataObject containing the values of all dataType=true properties (excluding the ChangeSummary property).

DataObject shallowCopy = copyHelper.copyShallow(dataObject);

Deep Copy

Create a copy of the entire tree.

DataObject deepCopy = copyHelper.copy(dataObject);

EqualityHelper - Compare DataObjects

EqualityHelper provides a convenient means of comparing DataObjects.

EqualityHelper equalityHelper = helperContext.getEqualityHelper();

Shallow Equal

Two DataObjects are considered shallow equal if the data objects are of the same type and all the values of all dataType=true properties (excluding the ChangeSummary property) are equal.

boolean isShallowEqual = equalityHelper.equalShallow(dataObject1, dataObject2);

Deep Equal

Two DataObjects are considered deep equal if the data objects and the trees that they belong to are both equal.

boolean isDeepEqual = equalityHelper.equal(dataObject1, dataObject2);
