Synchronize Timed Structure Starts (G Dataflow)

Last Modified: January 12, 2018

Synchronizes the start of timed structures you specify. This node adds the names of the timed structures to a synchronization group that waits until all timed structures in the group are ready to execute before running.

Timed structures in a synchronization group wait until all the timed structures in the group are ready to execute before running.

Programming Patterns
connector_pane_image
datatype_icon

clear

Boolean that determines if the node removes all existing timed structures from the synchronization group before adding the timed structures you specify.

True Clears the synchronization group before adding timed structures you specify.
False Does not clear the synchronization group.

Default: False

datatype_icon

replace

Boolean that determines whether the node will remove a timed structure from any synchronization group it belongs to before adding it to the synchronization group you specify.

True Timed structures are removed from any synchronization group they already belong to.
False Timed structures are not removed from any existing synchronization group. The node returns an error if a timed structure you specify in timed structure names in is a member of another group.

Default: True

datatype_icon

synchronization group name

Name to assign to the group of timed structures you want to synchronize.

Default: empty string

datatype_icon

timeout ms

Time, in milliseconds, that a timed structure waits on other members of the synchronization group to arrive at the synchronization point. If any of the timed structures in the group do not arrive in time, the timed structure returns an error. A value of -1 indicates to wait indefinitely.

Default: 1000

datatype_icon

timed structure names in

Names of the timed structures you want to synchronize. By default, the node deletes the timed structure from any group it already belongs to and adds it to the group you specify in synchronization group name. If you set replace to False and a timed structure you specify in timed structure names in is a member of another group, the node returns an error to indicate that it could not add the timed structure to the synchronization group.

Default: empty string array

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

timed structures names out

Names of all timed structures in the group after the node adds the names to the synchronization group you specify.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
