 org.tp23.antinstaller.runtime.exe.PropertyLoaderFilter
All known Subclasses: org.tp23.antinstaller.runtime.exe.EmbeddablePropertyLoaderFilter,
| PropertyLoaderFilter | | public class PropertyLoaderFilter implements ExecuteFilter(Code) | | Loads properties from a file of default properties if found.
the Installer element should define an attribute
loadDefaults with one of the following values.
false - do not look for defaults
prompt - look for properties and ask if they should be used if found
true - look for defaults if found load them
prompt-auto - weird case where installer permits zero user interaction running only from antinstaller-config.xml defaults
N.B. this is not a generic property loader but one specifically for properties files
generated by a previous run of an identical installer or one that according to the version
number is compatible, see PropertyTask for loading other property sets
