[jira] Reopened: (FELIX-2815) Difference between "instance" and
"provides"
[ https://issues.apache.org/jira/browse/FELIX-2815?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andriyko reopened FELIX-2815:
-----------------------------
Sorry, but it is STILL not clear what the "instance" is. Why do we need it?
It is first referred to under the section titled "Service Publication", as:
"The service is published as long as the instance is valid."
What instance??? You never introduced the notion of an instance before, and it is confusing.

> Key: FELIX-2815
> URL: https://issues.apache.org/jira/browse/FELIX-2815
> Project: Felix
> Issue Type: Bug
> Components: iPOJO
> Reporter: Andriyko
> Assignee: Clement Escoffier
> Labels: documentation, felix,, ipojo
>
> In the documentation on iPOJO Services:
> http://felix.apache.org/site/providing-osgi-services.html#ProvidingOSGiservices-Instancereconfiguration
> There is no clear explanation of what is the difference between <provides> and <instance>.
> It is not clear why "instance" is needed at all.
> Under the "Service Properties" heading on the page, the two are used interchangeably in the examples.
> For example, first "property" is configured with <provides>:
> <component classname="...FooProviderType1">
> <provides>
> <property name="foo" field="m_foo" value="Foo"/>
> <property name="static" type="java.lang.String" value="this is a static property"/>
> </provides>
> </component>
> and then immediately, with no explanation what-so-ever and <intsance> is used, with a tiny explanation that "The value can be given in the instance configuration":
> <instance component="...FooProviderType1">
> <property name="foo" value="My New Foo Value"/>
> <property name="static" value="My Value For Static"/>
> </instance>
