|
| public java.lang.String | getName()Name attribute will contain the path of a file relative to the
root directory of its fileset or the recorded path of a zip
entry.
example for a file with fullpath /var/opt/adm/resource.txt
in a file set with root dir /var/opt it will be

|
| public boolean | isDirectory()Tells if the resource is a directory.
if (isReference()) {

}
//default false:
return directory != null && directory.booleanValue();
|
| public boolean | isExists()The exists attribute tells whether a file exists.

|
| public void | setDirectory(boolean directory)Set the directory attribute.
checkAttributesAllowed();
this.directory = directory ? Boolean.TRUE : Boolean.FALSE;
|
| public void | setExists(boolean exists)Set the exists attribute.
checkAttributesAllowed();

|
| public int | size()Fulfill the ResourceCollection contract.
return isReference() ? ((Resource) getCheckedRef()).size() : 1;
|
| public final java.lang.String | toLongString()Get a long String representation of this Resource.
This typically should be the value of toString()
prefixed by a type description.
return isReference() ? ((Resource) getCheckedRef()).toLongString()
: getDataTypeName() + " \"" + toString() + '"";
|
