How to use the azure-mgmt-loganalytics.azure.mgmt.loganalytics.models.WorkspacePurgeBody function in azure-mgmt-loganalytics

def _purge_initial(
            self, resource_group_name, workspace_name, table, filters, custom_headers=None, raw=False, **operation_config):
        body = models.WorkspacePurgeBody(table=table, filters=filters)

        api_version = "2015-03-20"

        # Construct URL
        url = self.purge.metadata['url']
        path_format_arguments = {
            'resourceGroupName': self._serialize.url("resource_group_name", resource_group_name, 'str', max_length=90, min_length=1, pattern=r'^[-\w\._\(\)]+$'),
            'subscriptionId': self._serialize.url("self.config.subscription_id", self.config.subscription_id, 'str'),
            'workspaceName': self._serialize.url("workspace_name", workspace_name, 'str')
        }
        url = self._client.format_url(url, **path_format_arguments)

        # Construct parameters
        query_parameters = {}
        query_parameters['api-version'] = self._serialize.query("api_version", api_version, 'str')
