TemplexPlugin

TemplexPlugin - Plug-in support for the Templex interpreter.

Inputs

ents: an entity table.

src: a value table.

begin: a procedure to be called on the begin event (optional).

onrecord: a procedure to be called on the onrecord event.

end: a procedure to be called on the end event (optional).

opt_str: specify to pass a user-defined argument string (optional).

script: the file that contains the event procedure definitions.

Outputs

answer: a value table.

Notes

•	The entities in ents must match the binding of the values in src. For example, if src contains elemental scalars, ents must contain elements from the same pool.

•	The onrecord procedure is mandatory, begin and end procedures are optional.

Expression Builder

Requires *RegisterResultMathPlugin entry in preference file. See the Configuration section.

Example

<call name="TemplexPlugin" ents="ent_tab" src="src_tab"

begin="begin_proc" onrecord="record_proc"

end="end_proc"

script="templex_script_filepath"

answer="ans_tab " />

The query and action events that are added to the Templex interpreter accept string arguments (case insensitive), and are as follows:

Query/Action Function

Description

GetTableInfo

GetTableInfo supports table queries and accepts a single argument:

•	label – returns the table label.

•	domain – returns the table domain (“real” or “complex”).

GetTableInfo can be called in the Begin and End events.

GetRecordInfo

GetRecordInfo supports record queries and accepts the following arguments:

•	id: returns the entity ID attached to the value record.

•	partid: returns the part ID attached to the element (returns 0 for values not bound to elements).

•	config: returns the element configuration number.

•	data: returns the values in the record as a space-separated number.

•	tensor: valid for tensor value records only and accepts a 2nd parameter to extract invariants:

o	p1 – major principal

o	p2 – mid principal

o	p3 – minor principal

o	von – vonMises

•	vector: valid for vector values records only and accepts a 2nd parameter to extract invariants:

o	mag – vector magnitude.

GetRecordInfo can be called in the OnRecord event only.

AddRecord

AddRecord sends values to the destination table and accepts a string with an ID, followed by a space-separated list of values. For example, when adding a vector value, the call would appear as:

AddRecord “ent_id vec_val”

where:

ent_id is a variable that evaluates to the ID.

vec_val is a variable that evaluates to 3 vector components.

GetOption

GetOption(key)

Returns the string passed in the argument “opt_str” if specified, or the optional argument associated with key.

ThrowException

ThrowException sends a message to the controlling application and terminates execution of the plug-in operation. The syntax is as follows:

ThrowException $err_string

When a scripted plugin is run from HyperView, the exception string is output in the tk console window.
