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

# ------------------------------------------------------------------------------
# @IUSE
#
# 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.
#
# Build Java packages to native libraries
# ------------------------------------------------------------------------------
IUSE="${JAVA_PKG_IUSE} gcj multislot"

# ------------------------------------------------------------------------------
# @depend
#
# 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}"

# ------------------------------------------------------------------------------
# @rdepend
#
# Nothing special for RDEPEND... just the same as DEPEND.
# ------------------------------------------------------------------------------
