Constructor Detail

ImportSupport

public ImportSupport(java.lang.String layerName,
                     int layerIndex,
                     java.util.List<SessionReader.LayerDependency> layerDependencies)

Constructs a new ImportSupport.

Parameters:

layerName - layer name

layerIndex - layer index

layerDependencies - layer dependencies

Method Detail

addPostLayersTask

public void addPostLayersTask(java.lang.Runnable task)

Add a task, e.g. a message dialog, that should be executed in EDT after all layers have been added.

Parameters:

task - task to run in EDT

getInputStream

public java.io.InputStream getInputStream(java.lang.String uriStr)
                                   throws java.io.IOException

Return an InputStream for a URI from a .jos/.joz file. The following forms are supported: - absolute file (both .jos and .joz): "file:///home/user/data.osm" "file:/home/user/data.osm" "file:///C:/files/data.osm" "file:/C:/file/data.osm" "/home/user/data.osm" "C:\files\data.osm" (not a URI, but recognized by File constructor on Windows systems) - standalone .jos files: - relative uri: "save/data.osm" "../project2/data.osm" - for .joz files: - file inside zip archive: "layers/01/data.osm" - relative to the .joz file: "../save/data.osm" ("../" steps out of the archive)

Parameters:

uriStr - URI as string

Returns:

the InputStream

Throws:

java.io.IOException - Thrown when no Stream can be opened for the given URI, e.g. when the linked file has been deleted.

getFile

public java.io.File getFile(java.lang.String uriStr)
                     throws java.io.IOException

Return a File for a URI from a .jos/.joz file. Returns null if the URI points to a file inside the zip archive. In this case, inZipPath will be set to the corresponding path.

Parameters:

uriStr - the URI as string

Returns:

the resulting File

Throws:

java.io.IOException - if any I/O error occurs

isZip

public boolean isZip()

Determines if we are reading from a .joz file.

Returns:

true if we are reading from a .joz file, false otherwise

getLayerName

public java.lang.String getLayerName()

Name of the layer that is currently imported.

Returns:

layer name

getLayerIndex

public int getLayerIndex()

Index of the layer that is currently imported.

Returns:

layer index

getLayerDependencies

public java.util.List<SessionReader.LayerDependency> getLayerDependencies()

Dependencies - maps the layer index to the importer of the given layer. All the dependent importers have loaded completely at this point.

Returns:

layer dependencies

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
