public interface PlasmaDataObject
extends 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.

void setDataGraph(DataGraph dataGraph)
```
    Deprecated.
  - setContainer
```
@Deprecated
void setContainer(DataObject container)
```
    Deprecated.
    
    Sets the current container for this DataObject
  - setContainmentProperty
```
@Deprecated
void setContainmentProperty(Property containmentProperty)
```
    Deprecated.
    
    Sets the declared reference Property within the Type for the container which is our current containment reference property
    
    Parameters:
    
    containmentProperty - the containment property, which must be a declared property within the type for the current container data object.
  - reparent
```
@Deprecated
void reparent(PlasmaDataObject container,
                           Property containmentProperty)
```
    Deprecated.
    
    Transfers this data object to another data graph, makes this data object to be contained by the given container data object using the given containment property. The property and its opposite if exists, are automatically set and flagged as modified in the change summary. This data object automatically becomes part of the data graph of the given container.
    
    Parameters:
    
    container - the container data object.
    
    containmentProperty - the containment property, which must be a declared property within the type for the given container data object.
