Adds a property to a type

说明

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 ] ) : void

Warning

此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。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
PECL sdo 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));
?>
