Constructor Detail

DefaultParserHelper

public DefaultParserHelper(ICondition condition,
                           OAVTypeModel tmodel)

Create a BDI parser helper.

Parameters:

condition - The predefined condition.

state - The state.

returnvar - The return value variable (if return value condition).

Method Detail

getVariable

public Variable getVariable(java.lang.String name)

Get a variable with a given name.

Specified by:

getVariable in interface IParserHelper

Parameters:

name - The variable name.

Returns:

The variable.

addVariable

public void addVariable(Variable var)

Add a variable.

Specified by:

addVariable in interface IParserHelper

Parameters:

var - The variable.

isPseudoVariable

public boolean isPseudoVariable(java.lang.String name)

Test, if a name refers to a pseudo variable (e.g. $beliefbase).

Specified by:

isPseudoVariable in interface IParserHelper

Parameters:

name - The variable name.

Returns:

True, if the name is a pseudo variable.

getConditions

public java.util.List getConditions()

Get the conditions after parsing.

Specified by:

getConditions in interface IParserHelper

getBuildContext

public BuildContext getBuildContext()

Get the build context.

Specified by:

getBuildContext in interface IParserHelper

getReplacementType

public java.lang.Object[] getReplacementType(OAVObjectType type)

Get the replacement type for an object type in an existential declaration E.g. when a flyweight should be replaced by the real state type (IGoal $g instead of goal $g)

Specified by:

getReplacementType in interface IParserHelper

Parameters:

type - The type to be replaced.

Returns:

a tuple containing the replacement type and the replacement value source (e.g. a function call recreating the flyweight from the state object).
