EASL Code Generation Macros

Enterprise Architect provides a number of Enterprise Architect Simulation Library (EASL) code generation macros to generate code from behavioral models. These are:

EASL_INIT
EASL_GET
EASLList and
EASL_END

EASL_INIT

The EASL_INIT macro is used to initialize an EASL behavior model. The behavior model code generation is dependent on this model.

Aspect	Description
Syntax	%EASL_INIT(<<GUID>>)% where: <<GUID>> is the GUID of the Object (usually a Class element) that is the owner of the behavior model

Aspect

Description

Syntax

%EASL_INIT(<<GUID>>)%

where:

<<GUID>> is the GUID of the Object (usually a Class element) that is the owner of the behavior model

EASL_GET

The EASL_GET macro is used to retrieve a property or a collection of an EASL object. The EASL objects and the properties and collections for each object are identified in the EASL Collections and EASL Properties topics.

Aspect	Description
Syntax	$result = %EASL_GET(<<Property>>, <<Owner ID>>, <<Name>>)% where: <<Property>> is one of "Property", "Collection", "At", "Count", or "IndexOf" <<OwnerID>> is the ID of the owner object for which the property/collection is to be retrieved <<Name>> is the name of the property or Collection being accessed $result is the returned value; this is “” if not a valid property If <<Property>> is: "At", then <<OwnerID>> is the ID of a collection and <<Name>> is the index into the collection for which the item is to be retrieved "Count", then <<Owner ID>> is the ID of a collection and <<Name>> is not used; it will retrieve the item number in the collection "IndexOf", then <<Owner ID>> is the ID of a collection and <<Name>> is the ID of the item in the collection; it will retrieve the index (string format) of the item within the collection
Example	$sPropName = %EASL_GET("Property", $context, "Name")%

Aspect

Description

Syntax

$result = %EASL_GET(<<Property>>, <<Owner ID>>, <<Name>>)%

where:

<<Property>> is one of "Property", "Collection", "At", "Count", or "IndexOf"
<<OwnerID>> is the ID of the owner object for which the property/collection is to be retrieved
<<Name>> is the name of the property or Collection being accessed
$result is the returned value; this is “” if not a valid property

If <<Property>> is:

"At", then <<OwnerID>> is the ID of a collection and <<Name>> is the index into the collection for which the item is to be retrieved
"Count", then <<Owner ID>> is the ID of a collection and <<Name>> is not used; it will retrieve the item number in the collection
"IndexOf", then <<Owner ID>> is the ID of a collection and <<Name>> is the ID of the item in the collection; it will retrieve the index (string format) of the item within the collection

Example

$sPropName = %EASL_GET("Property", $context, "Name")%

EASLList

The EASLList macro is used to render each object in an EASL collection using the appropriate template.

Aspect	Description
Syntax	$result = %EASLList=<<TemplateName>> @separator=<<Separator>> @indent=<<indent>> @owner=<<OwnedID>> @collection=<<CollectionName>> @option1=<<OPTION1>> @option2=<<OPTION2>>......... @optionN=<<OPTIONN>>% where: <<TemplateName>> is the name of any behavioral model template or custom template <<Separator>> is a list separator (such as “\n”) <<indent>> is any indentation to be applied to the result <<OwnedID>> is the ID of the object that contains the required collection <<CollectionName>> is the name of the required collection <<OPTION1>...<<OPTION99>> are miscellaneous options that might be passed on the template; each option is given as an additional input parameter to the template $result is the resultant value; this is “” if not a valid collection
Example	$sStates = %EASLList="State" @separator="\n" @indent="\t" @owner=$StateMachineGUID @collection="States" @option=$sOption%

Aspect

Description

Syntax

$result = %EASLList=<<TemplateName>> @separator=<<Separator>>

@indent=<<indent>> @owner=<<OwnedID>>

@collection=<<CollectionName>> @option1=<<OPTION1>>

@option2=<<OPTION2>>......... @optionN=<<OPTIONN>>%

where:

<<TemplateName>> is the name of any behavioral model template or custom template
<<Separator>> is a list separator (such as “\n”)
<<indent>> is any indentation to be applied to the result
<<OwnedID>> is the ID of the object that contains the required collection
<<CollectionName>> is the name of the required collection
<<OPTION1>...<<OPTION99>> are miscellaneous options that might be passed on the template; each option is given as an additional input parameter to the template
$result is the resultant value; this is “” if not a valid collection

Example

$sStates = %EASLList="State" @separator="\n" @indent="\t"

@owner=$StateMachineGUID @collection="States" @option=$sOption%

EASL_END

The EASL_END macro is used to release the EASL behavior model.

Aspect	Description
Syntax	%EASL_END%
