| Resource | | public interface Resource (Code) | | Represents a resource in an Ivy
Repository . The resource interface allows one to obtain
the following information about a resource:
- resource name/identifier in repository syntax
- date the resource was last modified.
- size of the resource in bytes.
- if the resource is available.
Implementation Notes
In implementing the interface you need to ensure the following behaviors:
- All of the methods specified in the interface fail by returning an empty value
(
false, 0, "").
In other words, the specified interface methods should not throw RuntimeExceptions.
- Failure conditions should be logged using the
org.apache.ivy.util.Message.verbose method.
- Failure of one of the interface's specified methods results in all other interface specified
methods returning an empty value (
false, 0, "").
