Constructor Details

JARDesc

public JARDesc(URL location,
 VersionString version,
 String part,
 boolean lazy,
 boolean main,
 boolean nativeJar,
 boolean cacheable)

Create a JAR descriptor.

Parameters:

location - the location of the JAR file

version - the required JAR versions, or null

part - the part name, or null

lazy - whether to load the JAR on demand

main - whether the JAR contains the main class

nativeJar - whether the JAR contains native libraries

cacheable - whether the JAR can be cached or not

Method Details

getLocation

public URL getLocation()

Returns:

the URL of the JAR file.

getVersion

public VersionString getVersion()

Returns:

the required version of the JAR file.

setVersion

public void setVersion(VersionString version)

getPart

public String getPart()

Returns:

the part name, or null if not specified in the JNLP file.

isNative

public boolean isNative()

Returns:

true if the JAR file contains native code libraries.

isEager

public boolean isEager()

Returns:

true if the JAR file should be downloaded before starting the application.

isLazy

public boolean isLazy()

Returns:
