Getting/Setting Attributes
This section describes how to get and set object attributes using the Java semantic interfaces.
For more information on getting/setting attributes using administration interfaces, see Attributes. For more information on getting/setting attributes using PCD interfaces, see Contexts and Attributes.
Procedure
In the following examples, obj is a semantic Java object. For more information on retrieving an object, see Looking Up Objects.
● Getting Attributes and Meta-Attributes
response.write(obj.getAttribute("attribute"));
response.write(obj.getMetaAttribute("attribute", "meta-attribute"));
Text attributes generally require an additional parameter that indicates the locale.
The following attributes require the use of the locale:
○ com.sap.portal.pcm.Title
○ com.sap.portal.pcm.Description
The following meta-attributes require the use of the locale:
○ plainDescription
○ longDescription
○ category
○ validValueTitle0, validValueTitle1, and so forth.
response.write (obj.getAttribute ("attribute", request.getLocale() ) );
· Setting Attributes
obj.putAttribute("attribute","value");
obj.save();
Attribute Constants
To specify an attribute, use the designated constant for that attribute. The constants for each semantic type are located in a corresponding interface in the com.sap.portal.pcm.attributes package.
For example, the constants for iView attributes are located in the IAttriView interface. The following code checks whether the current iView allows browser caching:
response.write(
obj.getAttribute(IAttriView.ATTRIBUTE_ALLOW_BROWSER));
