Method Detail

supportsCapability

public TriState supportsCapability(FileSystemCapabilityType<?> type)

Description copied from interface: FileSystemDelegate

Does the file system support the specified capability?

Parameters:

type - The file system capability type identifier.

Returns:

YES, NO or DONT_CARE

getCapabilityOrNull

public <T extends FileSystemCapability> T getCapabilityOrNull(FileSystemCapabilityType<T> type)

Description copied from interface: FileSystemDelegate

Get the file system capability object for the requested capability. This may be called with unsupported file system capability types. In that case, the method should return null.

Parameters:

type - The file system capability type.

Returns:

The file system capability object or null if the file system capability is not supported by this capability visitor.

getSupportedCapabilities

public Set<FileSystemCapabilityType<?>> getSupportedCapabilities()

Description copied from interface: FileSystemDelegate

Get the set of supported file system capability types for the file system.

Returns:

The set of supported file system capability types.

supportsCapabilityForEntity

public TriState supportsCapabilityForEntity(EntityImplementation ei,
                                            EntityCapabilityType<?> type)

Description copied from interface: FileSystemDelegate

Does the file system or capability provider support the requested entity capability for the supplied entity?

Parameters:

ei - The entity.

type - The entity capability type.

Returns:

YES, NO or DONT_CARE

See Also:

FileSystem.supportsCapabilityForEntity(org.entityfs.EntityView, EntityCapabilityType)

supportsCapabilityForEntityType

public TriState supportsCapabilityForEntityType(EntityType et,
                                                EntityCapabilityType<?> type)

Description copied from interface: FileSystemDelegate

Does the file system or capability provider support the requested entity capability for entities of the supplied type?

This method should return true also if the file system supports the capability for only some of the entities of the supplied type.

Parameters:

et - The entity type.

type - The entity capability type.

Returns:

YES, NO or DONT_CARE.
