Class FMUFile

java.lang.Object

org.ptolemy.fmi.FMUFile

public class FMUFile
extends java.lang.Object

Parse a Functional Mock-up Interface (FMI) 1.0 Functional Mock-up Unit (FMU) file and create a FMIModelDescription for later use.

The parseFMUFile() method in this class is the primary entry point into this package.

Method Detail

fmuSharedLibrary

public static java.lang.String fmuSharedLibrary(FMIModelDescription fmiModelDescription)
                                         throws java.io.IOException

Return the name of the shared library from a .fmu file.

Parameters:

fmiModelDescription - The representation of the model that was read in by {#parseFMUFile}.

Returns:

The canonical path of the shared library.

Throws:

java.io.IOException - If thrown while determining the canonical path of the library.

parseFMUFile

public static FMIModelDescription parseFMUFile(java.lang.String fmuFileName)
                                        throws java.io.IOException

Read in a .fmu file and parse the modelDescription.xml file. If the same file has been previously read, then return the FMIModelDescription from that previous reading. Note that this does not load the shared library. That is loaded upon the first attempt to use the procedures in it. This is important because we want to be able to view a model that references an FMU even if the FMU does not support the current platform.

Parameters:

fmuFileName - the .fmu file

Returns:

An object that represents the structure of the modelDescriptionFile.xml file.

Throws:

java.io.IOException - If the file cannot be unzipped or the modelDescription.xml file contained by the fmuFileName zip file cannot be parsed.

unzip

public static java.util.List<java.io.File> unzip(java.lang.String zipFileName)
                                          throws java.io.IOException

Unzip a file into a temporary directory. Based on http://java.sun.com/developer/technicalArticles/Programming/compression/.

Parameters:

zipFileName - The file to be unzipped.

Returns:

the list of files that were extracted.

Throws:

java.io.IOException - if the file cannot be opened, if there are problems reading the zip file or if there are problems creating the files or directories.

getIs32Bit

public static boolean getIs32Bit()

Return true if this is a 32bit JVM.

Returns:

true if this is a 32bit JVM.
