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();
Load
Create Document
Save
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);
