Detailed Description

Protocol independent message processessing state.

No longer XML only

Deals with generic namespace and xmlns optimization and tries to keep changing the default namespace so most nested elements do not have prefixes.

Deals with the NETCONF requirement that the attributes in <rpc> are returned in <rpc-reply> unchanged. Although XML allows the xnmlns prefixes to change, the same prefixes are used in the <rpc-reply> that the NMS provided in the <rpc>.

NOTE: The xml_msg_hst_t strust is used for both XML and JSON encoding It is no longer XML-specific!!!

Macro Definition Documentation

◆ XML_MSG_ACTION_PARENT_MODE

#define XML_MSG_ACTION_PARENT_MODE ( M ) (M)->action_parent_mode

action_parent_mode is TRUE if the XPath request and maybe GET2/AIO requests is for retrieval of the action parent, needed for complex NMDA XPath validation.

Must make sure that default NP containers are added in this mode. They can be ignored for client retrieval operations but not for NMDA action parent validation

◆ XML_MSG_FL_DELTA

#define XML_MSG_FL_DELTA bit7

indicates that IfModifiedSince and IfUnmodifiedSince filters cause only the changed nodes to be returned

     1 == return just the descendant nodes that match the filter
     0 == return all descendant nodes

◆ XML_MSG_FL_PREFIX

#define XML_MSG_FL_PREFIX bit0

xml_msg_hdr_t flags field bit definitions start here if PREFIX set then prefixes will be used for element start and end tags.

FALSE then default NS will be used so no prefixes will be needed except for XML content with QNames

◆ XML_MSG_SKIP_EMPTY_NPCON

#define XML_MSG_SKIP_EMPTY_NPCON ( M ) (M)->skip_empty_npcon

flag to indicate the empty NP containers should be skipped.

This should only be done on the RPC reply to the client, not YControl messages. Cannot be set to true on subsystems

◆ XML_MSG_SM_MPID

#define XML_MSG_SM_MPID ( M ) (M)->sm_mpid

the schema mount MPID active in the request will be NULL unless WITH_SCHEMA_MOUNT=1 and also ncx_get_sm_active() is true.

Will be present for mounted RPC and action requests
