# @BLURB: Eclass for Java Packages
# @DESCRIPTION:
# This eclass should be inherited for pure Java packages, or by packages which
# need to use Java.

inherit java-utils-2

# @ECLASS-VARIABLE: JAVA_PKG_IUSE
# @DEFAULT_UNSET
# @DESCRIPTION:
# Use JAVA_PKG_IUSE instead of IUSE for doc, source and examples so that
# the eclass can automatically add the needed dependencies for the java-pkg_do*
# functions.
IUSE="${JAVA_PKG_IUSE}"

# Java packages need java-config, and a fairly new release of Portage.
# JAVA_PKG_E_DEPEND is defined in java-utils.eclass.
DEPEND="${JAVA_PKG_E_DEPEND}"

# Nothing special for RDEPEND... just the same as DEPEND.
