public interface DataObject
A data object is a representation of some structured data. It is the fundamental component in the SDO (Service Data Objects) package. Data objects support reflection, path-based accesss, convenience creation and deletion methods, and the ability to be part of a data graph.
Each data object holds its data as a series of Properties
.
Properties can be accessed by name, property index, or using the property meta object itself.
A data object can also contain references to other data objects, through reference-type Properties.
A data object has a series of convenience accessors for its Properties.
These methods either use a path (String),
a property index,
or the property's meta object
itself, to identify the property.
Some examples of the path-based accessors are as follows:
DataObject company = ...; company.get("name"); is the same as company.get(company.getType().getProperty("name")) company.set("name", "acme"); company.get("department.0/name") is the same as ((DataObject)((List)company.get("department")).get(0)).get("name") .n indexes from 0 ... implies the name property of the first department company.get("department[1]/name") [] indexes from 1 ... implies the name property of the first department company.get("department[number=123]") returns the first department where number=123 company.get("..") returns the containing data object company.get("/") returns the root containing data object
There are general accessors for Properties, i.e., get
and set
,
as well as specific accessors for the primitive types and commonly used data types like
String, Date, List, BigInteger, and BigDecimal.

boolean isSet(Property property)
isSet() for many-valued Properties returns true if the List is not empty and false if the List is empty. For single-valued Properties it returns true if the Property has been set() and not unset(), and false otherwise. Any call to set() without a call to unset() will cause isSet() to return true, regardless of the value being set. For example, after calling set(property, property.getDefault()) on a previously unset property, isSet(property) will return true, even though the value of get(property) will be unchanged.
