Detailed Description

XPath Filtering used by NETCONF and RESTCONF Operations.

Supports <get-config>, <get>, and <get-data> operations. Calls local and/or remote GET2 callbacks if needed to get the requested data

Function Documentation

◆ agt_xpath_output_cvt_filter()

status_t agt_xpath_output_cvt_filter ( ses_cb_t scb,
rpc_msg_t msg,
const cfg_template_t cfg,
xpath_pcb_t pcb,
boolean  getop,
int32  indent 
)

Output an XPath filter converted from Subtree.

Evaluate the XPath filter against the specified config root, and output the result of the <get> or <get-config> operation to the specified session Source is a converted subtree filter!!

Parameters
scbsession control block
msgrpc_msg_t in progress
cfgconfig target to check against
pcbXPath control block to use
getopTRUE if this is a <get> and not a <get-config> The target is expected to be the <running> config, and all state data will be available for the filter output.
FALSE if this is a <get-config> and only the specified target in available for filter output
indentstart indent amount
Returns
status

◆ agt_xpath_output_filter()

status_t agt_xpath_output_filter ( ses_cb_t scb,
rpc_msg_t msg,
const cfg_template_t cfg,
boolean  getop,
int32  indent 
)

Output an XPath filter.

Evaluate the XPath filter against the specified config root, and output the result of the <get> or <get-config> operation to the specified session

Parameters
scbsession control block
msgrpc_msg_t in progress
cfgconfig target to check against
getopTRUE if this is a <get> and not a <get-config> The target is expected to be the <running> config, and all state data will be available for the filter output.
FALSE if this is a <get-config> and only the specified target in available for filter output

◆ agt_xpath_test_filter()

boolean agt_xpath_test_filter ( xml_msg_hdr_t msghdr,
ses_cb_t scb,
val_value_t selectval,
val_value_t val 
)

Test an XPath filter for a notification.

Evaluate the XPath filter against the specified config root, and just test if there would be any <eventType> element generated at all

Does not write any output based on the XPath evaluation

Parameters
msghdrmessage header in progress (for access control)
scbsession control block
selectvalfilter value struct to use
valtop of value tree to compare the filter against
!!! not written – not const in XPath in case
!!! a set-by-xpath function ever implemented
Returns
TRUE if filter passed or FALSE if error or did not pass
