Class JREDesc

java.lang.Object
net.adoptopenjdk.icedteaweb.jnlp.element.resource.JREDesc
public class JREDesc extends Object
The java element (or the j2se element) (sub-element of resources) specifies what Java Runtime Environment (JRE) versions an application is supported on, as well as standard parameters to the Java Virtual Machine. Several JREs can be specified in the JNLP file, which indicates a prioritized list of the supported JREs, with the most preferred version first.

      Returns:
      true if the JRE version is a Java platform version (java.specification.version property) or false if it is a product version (java.version property).

    • getVendor

      public String getVendor()

    • getLocation

      public URL getLocation()
      Returns:
      the JRE version string.

    • getMaximumHeapSize

      public String getMaximumHeapSize()
      Returns:
      the maximum heap size in bytes.

    • getInitialHeapSize

      public String getInitialHeapSize()
      Returns:
      the initial heap size in bytes.

    • getResourcesDesc

      public List<ResourcesDesc> getResourcesDesc()
      Returns:
      the resources defined for this JRE.

    • isRequire32Bit

      public boolean isRequire32Bit()

    • getAllVmArgs

      public List<String> getAllVmArgs()
      Returns:
