This is the class that will be called to perform operation from the xrl target.
| static string policy_target_name | policy_target_name | 
| PolicyTarget (XrlStdRouter& rtr) | PolicyTarget | 
Parameters:
| rtr | Xrl router used by this XORP process. | 
| bool  running () | running | 
Returns: true if process is running.
| void  shutdown () | shutdown | 
| void  create_term (const string& policy, const string& term) | create_term | 
Attempts to create a term. Terms are appended in existing policies [currently no way of inserting a term in a specific position].
Exception is thrown on error.
Parameters:
| policy | policy in which term should be created. | 
| term | name of term to create. | 
| void  delete_term (const string& policy, const string& term) | delete_term | 
Attempts to delete a term.
Exception is thrown on error.
Parameters:
| policy | policy in which term should be deleted. | 
| term | name of the term. | 
| void  update_term_source (const string& policy,
			    const string& term,
			    const string& source) | update_term_source | 
Updates the source block of a term.
Exception is thrown on error.
Parameters:
| policy | policy in which term should be updated. | 
| term | term which should be updated. | 
| source | un-parsed source configuration block of term. | 
| void  update_term_dest (const string& policy,
			  const string& term,
			  const string& dest) | update_term_dest | 
Updates the source block of a term.
Exception is thrown on error.
Parameters:
| policy | policy in which term should be updated. | 
| term | term which should be updated. | 
| dest | un-parsed dest configuration block of term. | 
| void  update_term_action (const string& policy,
			    const string& term,
			    const string& action) | update_term_action | 
Updates the source block of a term.
Exception is thrown on error.
Parameters:
| policy | policy in which term should be updated. | 
| term | term which should be updated. | 
| action | un-parsed action configuration block of term. | 
| void  create_policy (const string& policy) | create_policy | 
Attempts to create a policy.
Exception is thrown on error.
Parameters:
| policy | name of policy to create. | 
| void  delete_policy (const string& policy) | delete_policy | 
Attempts to delete a policy.
Exception is thrown on error.
Parameters:
| policy | name of policy to delete. | 
| void  create_set (const string& name) | create_set | 
Attempts to create a policy.
Exception is thrown on error.
Parameters:
| name | name of set to create. | 
| void  update_set (const string& name, const string& elements) | update_set | 
Attempts to update set elements.
Exception is thrown on error.
Parameters:
| name | name of set to update. | 
| elements | the elements of a set comma separated. | 
| void  delete_set (const string& name) | delete_set | 
Attempts to delete a set.
Exception is thrown on error.
Parameters:
| name | name of set to create. | 
| void  update_import (const string& protocol, const string& policies) | update_import | 
Updates the import policy list for a protocol and triggers a delayed commit.
Parameters:
| protocol | protocol for which to update imports. | 
| policies | comma separated policy list. | 
| void  update_export (const string& protocol, const string& policies) | update_export | 
Updates the export policy list for a protocol and triggers a delayed commit.
Parameters:
| protocol | protocol for which to update imports. | 
| policies | comma separated policy list. | 
| void  commit (uint32_t msec) | commit | 
Commit all configuration changes, but trigger a delayed update to the actual policy filters.
Parameters:
| msec | milliseconds after which policy filters should be updated. | 
| string  get_conf () | get_conf | 
Returns: string representation of configuration.
| void  birth (const string& tclass, const string& tinstance) | birth | 
Announce birth of a XORP process.
Parameters:
| tclass | target class. | 
| tinstance | target instance of class. | 
| void  death (const string& tclass, const string& tinstance) | death | 
Announce death of a XORP process.
Parameters:
| tclass | target class. | 
| tinstance | target instance of class. | 
| void  configure_varmap (const string& conf) | configure_varmap | 
Configure the variable map used for semantic checking. This should be initialized only once at startup.
Dynamic configuration may easily be implemented by invalidiating policies in the configuration class.
Dynamic addition of variables should be safe. It is the removal and update which needs to trigger a policy to be flagged as modified.
Parameters:
| conf | un-parsed configuration of variable map. |
