DIAMETER_RES_T


Retrieves header information and AVPs from Diameter responses.

AVPs can be retrieved by:

  • Directly specifying the AVP codes in the form: DIAMETER.RES.AVP( ). For example, to retrieve the Auth-Application-Id AVP (code 258), you can use the expression: DIAMETER.RES.AVP(258).
  • Using aliases that are provided for important AVPs. For example, the Auth-Application-Id AVP has the alias AUTH_APPLICATION_ID. So, the expression to retrieve the Auth-Application-Id AVP by using the alias is DIAMETER.RES.AUTH_APPLICATION_ID.

General usage: DIAMETER.RES.

This topic lists the expressions that are provided by this class.

Note : Expressions with the * symbol are inherited / promoted from diameter_message_t

IS_ERROR

Returns true if the E (error) command flag is set for the response.

Returns: bool_at


*REDIRECT_HOST

Returns the Redirect-Host AVP (code 292) from the response.

Returns: avp_t


*RESULT_CODE

Returns the Result-Code AVP (code 268) from the response.

Returns: avp_t


*TYPECAST_DIAMETER_MESSAGE_T

Convert diameter_res_t to diameter_message_t. Will raise an undef if the value is null, empty, or the value has an invalid format for the destination type. (diameter_message_t : Define common operations for Diameter.Req or Diameter.Res.)

Returns: diameter_message_t


*ACCOUNTING_SUB_SESSION_ID

Returns the Accounting-Sub-Session-Id AVP (code 287) from the message.

Returns: avp_t


*ACCT_APPLICATION_ID

Returns the Acct-Application-Id AVP (code 259) from the message. Note: expression can be used to retrieve the value as Unsigned32

Returns: avp_unum_t


*ACCT_MULTI_SESSION_ID

Returns the Acct-Multi-Session-Id AVP (code 50) from the message.

Returns: avp_t


*ACCT_SESSION_ID

Returns the Acct-Session-ID AVP (code 44) from the message.

Returns: avp_t


*APPLICATION_ID

Returns the Application-ID from the message.

Returns: unum_text_t


*AUTH_APPLICATION_ID

Returns the Auth-Application-Id AVP (code 258) from the message. Note: expression can be used to retrieve the value as Unsigned32

Returns: avp_unum_t


*AVP_END

Returns the location at the end of Diameter message (or in other words end of all AVPs) in Diameter message.

Returns: text_t


*AVP_LIST

Returns the AVP region in Diameter message (or in other words returns location at start of AVPs and length equal to Diameter message length excluding header).

Returns: text_t


AVP* (uint** avpcode)

Returns the specified AVP from the message.

For example, to get the AVP with code 263 from a Request, use the expression: DIAMETER.REQ.AVP(263).

Note: To get AVP that is nested inside a grouped AVP, use the AVP method from the avp_t class.

Parameters (expressions not allowed):

avpcode- AVP code

Returns: avp_t


AVP* (uint avpcode, uint** vendorid)

Returns the specified AVP in given vendor-id namespace from the message.

For example, to get the AVP with code 1001 and VendorId 10415 from a Request, use the expression: DIAMETER.REQ.AVP(1001, 10415).

Note: To get AVP that is nested inside a grouped AVP, use the AVP method from the avp_t class.

Parameters (expressions not allowed):

avpcode- AVP code

vendorid- Vendor Id

Returns: avp_t


*AVP_START

Returns the location at the start of AVPs (or in other words end of diameter header) in Diameter message.

Returns: text_t


*COMMAND_CODE

Returns the Command Code from the message.

Returns: unum_text_t


*END_TO_END_ID

Returns the End-to-End Identifier from the message.

Returns: unsigned_long_at


*FLAGS

Returns the value of Diameter Header flags in Diameter message.

Returns: diameter_flag_t


*HOP_BY_HOP_ID

Returns the Hop-by-Hop Identifier from the message.

Returns: unsigned_long_at


*IS_PROXIABLE

Returns true if the P (proxiable) command flag is set for the message.

Returns: bool_at


*LENGTH

Returns the Message Length from the message.

Returns: num_at


*ORIGIN_HOST

Returns the Origin-Host AVP (code 264) from the message.

Returns: avp_t


*ORIGIN_REALM

Returns the Origin-Realm AVP (code 296) from the message.

Returns: avp_t


*PRODUCT_NAME

Returns the Product-Name AVP (code 269) from the message.

Returns: avp_t


*SESSION_ID

Returns the Session-ID AVP (code 263) from the message.

Returns: avp_t


*SUPPORTED_VENDOR_ID

Returns the Supported-Vendor-Id AVP (code 265) from the message.

Returns: avp_t


*USER_NAME

Returns the User-Name AVP (code 1) from the message.

Returns: avp_t


*VENDOR_ID

Returns the Vendor-Id AVP (code 266) from the message.

Returns: avp_t


*VENDOR_SPECIFIC_APPLICATION_ID
