Examples with VersionRange org.osgi.framework.VersionRange used on opensource projects

Example 11 with VersionRange

use of org.osgi.framework.VersionRange in project aries by apache.

the class AbstractClause method parseParameters.

protected static Map<String, Parameter> parseParameters(String clause, boolean replaceVersionWithVersionRange) {
    Map<String, Parameter> parameters = new HashMap<String, Parameter>();

Example 12 with VersionRange

use of org.osgi.framework.VersionRange in project aries by apache.

the class SimpleFilter method convert.

/**
 * Converts a attribute map to a filter. The filter is created by iterating
 * over the map's entry set. If ordering of attributes is important (e.g.,
 * for hitting attribute indices), then the map's entry set should iterate
 * in the desired order. Equality testing is assumed for all attribute types
 * other than version ranges, which are handled appropriated. If the attribute
 * map is empty, then a filter that matches anything is returned.
 * @param attrs Map of attributes to convert to a filter.
 * @return A filter corresponding to the attributes.
