Adds a property to a type

说明

void SDO_DAS_DataFactory::addPropertyToType ( string $parent_type_namespace_uri , string $parent_type_name , string $property_name , string $type_namespace_uri , string $type_name [, array $options ] )

Warning

本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

Adds a property to a type. The type must already be known to the SDO_DAS_DataFactory (i.e. have been added using addType()). The property becomes a property of the type. This is how the graph model for the structure of an SDO_DataObject is built.

参数

parent_type_namespace_uri

The namespace URI for the parent type.

parent_type_name

The type name for the parent type.

property_name

The name by which the property will be known in the parent type.

type_namespace_uri

The namespace URI for the type of the property.

type_name

The type name for the type of the property

options

This array holds one or more key=>value pairs to set attribute values for the property. The optional keywords are:

many: A flag to say whether the property is many-valued. A value of 'true' adds the property as a many-valued property (default is 'false').
readOnly: A flag to say whether the property is read-only. A value of 'true' means the property value cannot be modified through the SDO application APIs (default is 'false').
containment: A flag to say whether the property is contained by the parent. A value of 'true' means the property is contained by the parent. A value of 'false' results in a non-containment reference (default is 'true'). This flag is only interpreted when adding properties which are data object types, otherwise it is ignored.
default: A default value for the property. Omitting this key means that the property does not have a default value. A property can only have a default value if it is a single-valued data type (primitive).

返回值

None.

更新日志

版本	说明
0.5.2	Optional parameters `many`, `readOnly`, and `containment` deprecated in favour of the `options` array.

范例

Example#1 A SDO_DAS_DataFactory::addPropertyToType() example

The following adds an 'addressline' property to a Person type. The person type is identified by its namespace, 'PersonNS', and type name, 'PersonType'. The type of the 'addressline' property is a many-valued SDO data type (primitive) with namespace 'commonj.sdo' and type name 'String'.


<?php
  $df->addPropertyToType('PersonNS', 'PersonType',
    'addressline', 'commonj.sdo', 'String', array('many'=>true));
?>
