                            ZipFile zf,
                            int bufSize)

Method Detail

getDirectoryNode

public org.entityfs.zip.ZipFileDirectoryNode getDirectoryNode(AbsoluteLocation loc)

This is used by the FSACZipEntries capability.

Returns:

The Zip file tree node that corresponds to the given location. This may be null for a non-existing node.

containsNode

public boolean containsNode(AbsoluteLocation loc)

getZipFile

public ZipFile getZipFile()

getEntityType

public EntityType getEntityType(AbsoluteLocation loc)

Get the type of the entity at the specified location. If the ZipFile does not contain any entry at the supplied location, this is interpreted as a directory entry.

loc - The location of the entity.

getZipEntry

public ZipEntry getZipEntry(AbsoluteLocation loc)

Get the ZipEntry for the supplied location. For directories, this may return null.

Parameters:

loc - The location to get the ZipEntry for.

Returns:

The ZipEntry or null.

registerDirectoryAdapter

public void registerDirectoryAdapter(ZipDirectoryAdapter da,
                                     AbsoluteLocation loc)

When a directory adapter is created, it is registered (through the FSACZipEntries capability) so that its location can be looked up when creating its child entity adapters.

Parameters:

da - The directory adapter

loc - The directory adapter's location

getDirectoryAdapterLocation

public AbsoluteLocation getDirectoryAdapterLocation(ZipDirectoryAdapter da)
