      gov.nasa.arc.brahms.common.data.ModelElement

All Implemented Interfaces:

gov.nasa.arc.brahms.common.IConstants, java.io.Serializable

public class InitialStatement
extends Condition

Initial statements define an initial state for an agent, object or the world, specifying the initial values for attributes or initializing the relationship between two concepts. Initial statements are turned into actual beliefs or facts when the model is initialized for a simulation run.

InitialStatement

public InitialStatement(Comparison c,
                        int truth)

Method Detail

setID

protected void setID()

Sets the unique identifier.

Overrides:

setID in class BrahmsObject

convertToStatement

public Statement convertToStatement(Concept concept)
                             throws gov.nasa.arc.brahms.common.exceptions.BrahmsException

Converts this initial statement to a Statement (AttributeStatement or RelationStatement) replacing any references to current with the specified concept.

Parameters:

concept - the concept to replace references to current, if current = null the fact is not processed and null is returned.

Returns:

Statement the result of the conversion

Throws:

gov.nasa.arc.brahms.common.exceptions.BrahmsException - if the initial statement is invalid

isOverridden

public boolean isOverridden(java.util.List<InitialStatement> statements)

Checks whether this initial statement would be overridden by one of the initial statements in a list obtained from more specific concepts

Parameters:

statements - a list of InitialStatement objects to be checked for overrides

Returns:

boolean true if this initial statement would be overridden, else false

toString

public java.lang.String toString()

Description copied from class: Condition

Returns a String representation of the condition.

Overrides:

toString in class Condition

Returns:

String the stringified condition
