Method Detail

checkAccess back to summary

public void checkAccess(Path path, AccessMode... modes) throws IOException

Implements abstract java.nio.file.spi.FileSystemProvider.checkAccess.

Doc from java.nio.file.spi.FileSystemProvider.checkAccess.

Checks the existence, and optionally the accessibility, of a file.

This method may be used by the isReadable, isWritable and isExecutable methods to check the accessibility of a file.

This method checks the existence of a file and that this Java virtual machine has appropriate privileges that would allow it access the file according to all of access modes specified in the modes parameter as follows:

Access Modes
Value	Description
`READ`	Checks that the file exists and that the Java virtual machine has permission to read the file.
`WRITE`	Checks that the file exists and that the Java virtual machine has permission to write to the file,
`EXECUTE`	Checks that the file exists and that the Java virtual machine has permission to `execute` the file. The semantics may differ when checking access to a directory. For example, on UNIX systems, checking for `EXECUTE` access checks that the Java virtual machine has permission to search the directory in order to access file or subdirectories.

If the modes parameter is of length zero, then the existence of the file is checked.

This method follows symbolic links if the file referenced by this object is a symbolic link. Depending on the implementation, this method may require to read file permissions, access control lists, or other file attributes in order to check the effective access to the file. To determine the effective access to a file may require access to several attributes and so in some implementations this method may not be atomic with respect to other file system operations.

Returns an existing `FileSystem` created by this provider. This method returns a reference to a `FileSystem` that was created by invoking the `newFileSystem(URI,Map)` method. File systems created by the `newFileSystem(Path,Map)` method are not returned by this method. The file system is identified by its `URI`. Its exact form is highly provider dependent. In the case of the default provider the URI's path component is `"/"` and the authority, query and fragment components are undefined (Undefined components are represented by `null`). Once a file system created by this provider is `closed` it is provider-dependent if this method returns a reference to the closed file system or throws `FileSystemNotFoundException`. If the provider allows a new file system to be created with the same URI as a file system it previously created then this method throws the exception if invoked after the file system is closed (and before a new instance is created by the `newFileSystem` method).
