| 874 | * INPUTS: <none> |
---|
| 875 | * OUTPUTS: <none> |
---|
| 876 | * |
---|
| 877 | * DESCRIPTION: This function works by first sending the inputs from the shell to the appropriate components |
---|
| 878 | * The first service should begin immeadiately, as should any others who have all of their input paramaters |
---|
| 879 | * When they complete, the output path is found and the data is transfered as it becomes available |
---|
| 880 | * Presumably at this point the second function has all of it's paramaters, so it begins to compute, and the cycle repeats |
---|
| 881 | * If the generated output is an overall output, it is sent on to the shell |
---|
| 882 | * "if" and "while" statements are handled by setting up a faux service that has a true input, a false input, and a boolean flag |
---|
| 883 | * If the true input is non-NULL and the flag is true, the statements execute |
---|
| 884 | * Likewise, if the false input is non-NULL and the flag is false, the statements execute |
---|
| 885 | * These flags are set during execution any time one of these faux services' inputs appear in an output statement |
---|
| 886 | * |
---|
| 887 | * |
---|
| 888 | * Rules for active missions (currently) |
---|
| 889 | * -Three inputs/outputs per service and per mission |
---|
| 890 | * -Inputs simply define a path, so multiple variables can be transmitted over the same input |
---|
| 891 | * -Each component that sends data must include the "output_finished" statement after each output is finished sending it's data |
---|
| 892 | * -All ordering constraints have been relaxed in this version; all data is stored locally and only sent when requested |
---|
| 893 | * -If support fully implemented |
---|
| 894 | * -Conditions must be boolean flags |
---|
| 895 | * -Flags are set by putting either the character string "true" or "false" on the buffer |
---|
| 896 | * -IMPORTANT: DB uses '@' to seperate individual statements; using '@' in the data stream will result in incorrect behavior |
