Constructor Detail

AdaptPermission back to summary

AdaptPermission	back to summary
public AdaptPermission(String filter, String actions) Creates a new granted `AdaptPermission` object. This constructor must only be used to create a permission that is going to be checked. Examples: (adaptClass=com.acme.) (&(signer=\,o=ACME,c=US)(adaptClass=com.acme.)) (signer=\,o=ACME,c=US) When a signer key is used within the filter expression the signer value must escape the special filter chars ('', '(', ')'). The name is specified as a filter expression. The filter gives access to the following attributes: signer - A Distinguished Name chain used to sign the exporting bundle. Wildcards in a DN are not matched according to the filter string rules, but according to the rules defined for a DN chain. location - The location of the exporting bundle. id - The bundle ID of the exporting bundle. name - The symbolic name of the exporting bundle. adaptClass - The name of the type to which an object can be adapted. Filter attribute names are processed in a case sensitive manner. Parameters filter:String A filter expression. Filter attribute names are processed in a case sensitive manner. A special value of `""` can be used to match all adaptations. actions:String `adapt`. Exceptions IllegalArgumentException: If the filter has an invalid syntax.

public AdaptPermission(String filter, String actions)

Creates a new granted AdaptPermission object. This constructor must only be used to create a permission that is going to be checked.

Examples:

(adaptClass=com.acme.*)
(&(signer=\*,o=ACME,c=US)(adaptClass=com.acme.*))
(signer=\*,o=ACME,c=US)

When a signer key is used within the filter expression the signer value must escape the special filter chars ('*', '(', ')').

The name is specified as a filter expression. The filter gives access to the following attributes:

signer - A Distinguished Name chain used to sign the exporting bundle. Wildcards in a DN are not matched according to the filter string rules, but according to the rules defined for a DN chain.
location - The location of the exporting bundle.
id - The bundle ID of the exporting bundle.
name - The symbolic name of the exporting bundle.
adaptClass - The name of the type to which an object can be adapted.

Filter attribute names are processed in a case sensitive manner.

Parameters

filter:String: A filter expression. Filter attribute names are processed in a case sensitive manner. A special value of "*" can be used to match all adaptations.
actions:String: adapt.

Exceptions

IllegalArgumentException:: If the filter has an invalid syntax.
