*file-store-attribute-view-factories*clj

A mapping of available file store attribute view types to factory functions for materialised records.

By default, there are no factories defined since Java NIO2 does not include any file store attribute views. However, since the file store attribute view framework is extensible and implementation dependent in Java NIO2, this var is dynamic and can be altered / rebound to support additional file store attribute views.

->file-storeclj

(->file-store file-store)

Converts the FileStore instance to a materialised record.

The returned record includes:

  • :name: the name of the file store,
  • :type: the type of the file store,
  • :read-only?: whether or not the file store is read only, as a boolean,
  • :total-space: the total space in the file store, in bytes,
  • :usable-space: the usable space for this JVM in the file store, in bytes,
  • :unallocated-space: the unallocated space in the file store, in bytes,
  • :block-size: the block size of the file store, when available, in bytes; nil when not available,
  • :delegate: the underlying instance.

The returned record implements ReloadFileStoreAttributes, FileAttributeViewSupport and FileStoreAttributeViewSupport.

Converts the [FileStore](https://docs.oracle.com/javase/7/docs/api/java/nio/file/FileStore.html)
instance to a materialised record.

The returned record includes:

  - `:name`: the name of the file store,
  - `:type`: the type of the file store,
  - `:read-only?`: whether or not the file store is read only, as a boolean,
  - `:total-space`: the total space in the file store, in bytes,
  - `:usable-space`: the usable space for this JVM in the file store, in
    bytes,
  - `:unallocated-space`: the unallocated space in the file store, in bytes,
  - `:block-size`: the block size of the file store, when available, in bytes;
    `nil` when not available,
  - `:delegate`: the underlying instance.

The returned record implements [[ReloadFileStoreAttributes]],
[[FileAttributeViewSupport]] and [[FileStoreAttributeViewSupport]].

->file-store-attribute-view-factoryclj

(->file-store-attribute-view-factory type)

Returns a file store attribute view factory for building materialised records for the supplied file store attribute view type when available. If no factory is available, an identity factory is returned which leaves the provided view unchanged.

See *file-store-attribute-view-factories* for details on supported types.

supports-file-attribute-viewclj

(supports-file-attribute-view file-store class-or-type)

Returns true if the file store supports the file attribute view identified by the class or type; returns false otherwise.

The class or type argument should be:

  • a Class instance corresponding to a class implementing FileAttributeView,
  • a string or keyword representing the view name of the file attribute view, defined by the underlying file system implementation.

FileStoreAttributeViewSupportcljprotocol

A protocol allowing the file store attribute view support of a file store to be determined, allowing attributes to be read in the case that file store attribute views are supported.

By default, Java NIO2 does not include any file store attribute views. However, the file store attribute view framework is extensible and implementation dependent so this protocol is provided in the case that a file system is in use that does provide file store attribute views.
