Overview

This method metadata information about one attribute on a factory. It can be called in Spell Code using send_wait method.

Usage

<source lang="javascript"> void send_wait (int timeout, object top_object, "call_attr", string factory_name, "dob_attr_type_info", string attribute_name) </source>

• timeout - how long (?in seconds?) should the method wait for finishing the method (0 means infinite)
• top_object - root object for the method (on which the method is called)
• factory_name - a factory containing the attribute (could be anything like pcat, cnt, cr, alg, ...)
• attr_name - a name of an attribute that we are looking for

Results

On success the resulted list is filled into a global array msg. Content of the array depends on an attribute type:

Type = VALUE

• msg[0] = attribute name
• msg[1] = "VALUE"
• msg[2] = exact attribute datatype
  • 0 = INTEGER
  • 1 = DOUBLE
  • 2 = STRING
  • 6 = LOCAL_TIME
  • 7 = DATE
  • 8 = DURATION
  • 9 = UUID
• msg[3] = string length in characters if msg[2] == 2
• msg[4] = Private/Public
• msg[5] = Required/Non-Required
• msg[6] = display name
• msg[7] = UI_INFO

Type = SREL

• msg[0] = attribute name
• msg[1] = "SREL"
• msg[2] = foreign factory name
• msg[3] = relation attribute of a foreign factory
• msg[4] = Private/Public
• msg[5] = Required/Non-Required
• msg[6] = display name
• msg[7] = ???
• msg[8] = UI_INFO

Type = BREL/QREL

• msg[0] = attribute name
• msg[1] = "QREL"
• msg[2] = foreign factory name
• msg[3] = WHERE query for QREL relations
• msg[4] = list of attributes used as parameters to WHERE query in msg[3]
• msg[5] = DOMSET name
• msg[6] = sorting definition
• msg[7] = list columns
• msg[8] = attribute name
• msg[9] = foreign attribute name for BREL relations
• msg[10] = UI_INFO

Type = LREL

• msg[0] = attribute name
• msg[1] = "LREL"
• msg[2] = name of intermediate relation factory (table)
• msg[3] = factory handler?
• msg[4] = attribute name
• msg[5] = UI_INFO

Examples

<source lang="javascript"> int i, num_args; send_wait( 0, top_object(), "call_attr", "cnt", "dob_attr_type_info", "last_name"); if ( msg_error()) {

   printf("Error: Can't get attributes info: %s\n", msg[0]);
   type = "VALUE";

} num_args = msg_length(); logf(SIGNIFICANT, "num_args = %s", num_args); for (i=0; i<num_args; i++)

   logf(SIGNIFICANT, "msg[%s] = %s", i, msg[i]);
