Returns the value of a BigInteger property identified by the specified property index. Returns the value of a BigDecimal property identified by the specified path. Returns the value of the specified BigDecimal property. Returns the value of a BigDecimal property identified by the specified property index. Returns the value of a property of either this object or an object reachable from it, as identified by the Returns the value of the given property of this object. Returns the value of the property at the specified index in property list Remove this object from its container and unset all its properties. Returns a new data object contained by this object using the specified property,ĬreateDataObject( propertyName)ĬreateDataObject( propertyName, String, Date, List, BigInteger, and BigDecimal. There are general accessors for properties, i.e., get and set,Īs well as specific accessors for the primitive types and commonly used data types like implies the name property of the first departmentĬompany.get("department") returns the first department where number=123Ĭompany.get(".") returns the containing data objectĬompany.get("/") returns the root containing data object
implies the name property of the first departmentĬompany.get("department/name") indexes from 1. Some examples of the path-based accessors are as follows:Ĭompany.get("name") is the same as company.get(company.getType().getProperty("name"))Ĭompany.get("department.0/name") is the same as ((DataObject)((List)company.get("department")).get(0)).get("name") Or the property's meta object itself, to identify the property. These methods either use a path (String),

Properties can be accessed by name, property index, or using the property meta object itself.Ī data object can also contain references to other data objects, through reference-type properties.Ī data object has a series of convenience accessors for its properties. It is the fundamental component in the SDO (Service Data Objects) package.ĭata objects support reflection, path-based accesss, convenience creation and deletion methods,Īnd the ability to be part of a data graph.Įach data object holds its data as a series of properties.
