public interface DataObject
extends java.io.Serializable

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.

get

java.lang.Object get(Property property)

Returns the value of the given property of this object.

If the property is many-valued, the result will be a List and each object in the List will be an instance of the property's type. Otherwise the result will directly be an instance of the property's type.

Parameters:

the value of the given property of the object.

set(Property, Object), unset(Property), isSet(Property)

set

void set(Property property,
         java.lang.Object value)

Sets the value of the given property of the object to the new value.

If the property is many-valued, the new value must be a List and each object in that list must be an instance of the property's type; the existing contents are cleared and the contents of the new value are added. Otherwise the new value directly must be an instance of the property's type and it becomes the new value of the property of the object.

Parameters:

value - the new value for the property.

See Also:

unset(Property), isSet(Property), get(Property)

isSet

boolean isSet(Property property)

Returns whether the property of the object is considered to be set.

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.

Parameters:

property - the property in question.

Returns:

whether the property of the object is set.

See Also:

set(Property, Object), unset(Property), get(Property)

unset

void unset(Property property)

Unsets the property of the object.

If the property is many-valued, the value must be an List and that list is cleared. Otherwise, the value of the property of the object is set to the property's default value. The property will no longer be considered set.

Parameters:

property - the property in question.
