| <div class="block">The base FileSystem implementation generally has no knowledge |
| of the capabilities of actual implementations. |
| Unless it has a way to explicitly determine the capabilities, |
| this method returns false. |
| Probe for a specific capability under the given path. |
| If the function returns <code>true</code>, this instance is explicitly |
| declaring that the capability is available. |
| If the function returns <code>false</code>, it can mean one of: |
| <ul> |
| <li>The capability is not known.</li> |
| <li>The capability is known but it is not supported.</li> |
| <li>The capability is known but the filesystem does not know if it |
| is supported under the supplied path.</li> |
| </ul> |
| The core guarantee which a caller can rely on is: if the predicate |
| returns true, then the specific operation/behavior can be expected to be |
| supported. However a specific call may be rejected for permission reasons, |
| the actual file/directory not being present, or some other failure during |
| the attempted execution of the operation. |
