ClasspathSpecifier
public static final class ClasspathSpecifier.Element extends Object implements Serializable
An element of a classpath. Elements may either be OSGI bundles or "plain old" java jars/directories. All elements must have a path object. In addition, elements may specify whether we are to cache the element on a per-node basis or on a per-job basis.

    • Element

      Create a new classpath for the given path.
      Parameters:
      path - the location of the element. May either be a directory or a file.

    • Element

      public Element(Path path, CacheScopeSpecifier cacheScope, boolean dynamic, OSGIOptions osgiOptions)
      Create a new classpath for the given path.
      Parameters:
      path - the location of the element. May either be a directory or a file.
      cacheScope - specifies where to cache the element
      dynamic - if true, the classpath element will be scanned each time we run a job to see whether its checksum has changed. if false, the checksum will be cached in-memory so that the checksum is only recomputed upon restart.
      osgiOptions - extra options for the case where this is an osgi classpath element. May be null in the case of a non-osgi element

    • dynamic

      public boolean dynamic()
      Returns whether the classpath element can be dynamically updated at runtime. If true, the classpath element will be scanned each time we run a job to see whether its checksum has changed. if false, the checksum will be cached in-memory so that so that the checksum is only recomputed upon restart.
      Returns:
      whether the classpath element can be dynamically updated at runtime

    • osgiOptions

      public OSGIOptions osgiOptions()
      Returns the osgi options of this element. These are extra options applicable to the case where this is an osgi classpath element.
      Returns:
      the osgi options scope of this element

    • path

      public ClasspathSpecifier.Element path(Path path)
      Returns a new ClasspathElement, overriding the path.
      Parameters:
      path - the new path
      Returns:
      a newly created ClasspathElement

    • cacheScope

      public ClasspathSpecifier.Element cacheScope(CacheScopeSpecifier cacheScope)
      Returns a new ClasspathElement, overriding the cacheScope.
      Parameters:
      cacheScope - the new cacheScope
      Returns:
      a newly created ClasspathElement

    • dynamic

      public ClasspathSpecifier.Element dynamic(boolean dynamic)
      Returns a new ClasspathElement, overriding dynamic.
      Parameters:
      dynamic - the new value for dynamic
      Returns:
      a newly created ClasspathElement

    • osgiOptions

      public ClasspathSpecifier.Element osgiOptions(OSGIOptions osgiOptions)
      Returns a new ClasspathElement, overriding the osgiOptions.
      Parameters:
      osgiOptions - the new osgiOptions
      Returns:
      a newly created ClasspathElement
