[Android.Runtime.Register("isExecutable", "(Ljava/nio/file/Path;)Z", "", ApiSince=26)]
public static bool IsExecutable (Java.Nio.FileNio.IPath? path);[<Android.Runtime.Register("isExecutable", "(Ljava/nio/file/Path;)Z", "", ApiSince=26)>]
static member IsExecutable : Java.Nio.FileNio.IPath -> boolParameters
- path
- IPath
the path to the file to check
Returns
true if the file exists and is executable; false
if the file does not exist, execute access would be denied because
the Java virtual machine has insufficient privileges, or access
cannot be determined
- Attributes
Remarks
Tests whether a file is executable. This method checks that a file exists and that this Java virtual machine has appropriate privileges to Runtime#exec 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.
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. Consequently, this method may not be atomic with respect to other file system operations.
Note that the result of this method is immediately outdated, there is no guarantee that a subsequent attempt to execute the file will succeed (or even that it will access the same file). Care should be taken when using this method in security sensitive applications.
