Classes
class	act_connection
	Connections. More...
class	ValueIdx
	This class is used to create an instance in a scope. The name comes from the fact that this is used to keep track of the index of a value within a particular type (rather than a flat data structure, one per instance) and so is not defined as a value-per-instance, but rather a value-per-type.

Function Documentation

_act_mk_raw_connection()

void _act_mk_raw_connection	(	act_connection *	c1,
		act_connection *	c2
	)

The union-find connection function. Make a simple connection, combining c1 and c2. c1 has the canonical connection pointer.

Parameters

c1	is the canonical one
c2	is the one to connect to c1

act_merge_attributes()

void act_merge_attributes	(	ValueIdx *	vx1,
		ValueIdx *	vx2,
		struct act_attr **	x,
		struct act_attr *	a
	)

Merge the attributes of two instances. The vx1 and vx2 pointers are used for error reporting only. The real merge happens between the attribute lists provided.

Parameters

vx1	is the name of one of the instances
vx2	is the name of the other instance
a	is the attribute list that should be merged
x	is the attribute list into which the attributes should be merged

act_mk_connection()

void act_mk_connection	(	UserDef *	ux,
		ActId *	id1,
		act_connection *	c1,
		ActId *	id2,
		act_connection *	c2
	)

Function used to actually make a connection. This also determines which of the two connections should be the canonical one according to the rules for an act_connection.

Parameters

id1	is the id for the first connection element
c1	is the connection pointer for id1
id2	is the id for the second connection element
c2	is the connection pointer for id2
ux	is the user-defined type, if any for the connection context. This is needed to determine which of the two is canonical.

act_print_attributes()

void act_print_attributes	(	FILE *	fp,
		act_attr *	a
	)

Print out the attribute list

Parameters

fp	is the output file
a	is the attribute list
