Create PolicyProvider instance

Parameters:

conf - configuration

xacmlParserFactory - XACML parser factory for parsing any XACML Policy(Set)

maxPolicySetRefDepth - maximum allowed depth of PolicySet reference chain (via PolicySetIdReference): PolicySet1 -> PolicySet2 -> ...; to be enforced by any instance created by this factory. A strictly negative value means no limit

expressionFactory - Expression factory for parsing XACML Expressions in the policies

combiningAlgRegistry - Combining algorithm registry for getting implementations of algorithms used in the policies

environmentProperties - global PDP configuration environment properties

otherHelpingPolicyProvider - other optional policy provider that helps the new instance resolve policy references that it cannot resolve on its own. It is meant to be a combination of the policy providers instantiated previously, if there was any.

Returns:

the instance

Throws:

IllegalArgumentException - if conf required but null
