Returns:

an Object that represents an actual implementation of this strategy inside an underlying selected solver.

getName

java.lang.String getName()

Returns the name of this strategy.

Returns:

the name of this strategy.

getObject

java.lang.Object getObject()

This method may be used to get an attached Business Object for this object.

Returns:

the Business Object attached to this object.

getSolver

Solver getSolver()

Returns a solver to which this strategy belongs.

Returns:

a solver to which this strategy belongs.

getType

SearchStrategy.SearchStrategyType getType()

Returns a type of this Search Strategy

Returns:

SearchStrategyType

getValueSelector

ValueSelector getValueSelector()

Returns a value selector that was set for this strategy

getVarReals

VarReal[] getVarReals()

Returns a an array of real variables that is in use by this strategy

getVars

Var[] getVars()

Returns a an array of integer variables that is in use by this strategy

getVarSelector

VarSelector getVarSelector()

Returns a variable selector that was set for this strategy

run

boolean run()

This method is used by CUSTOM strategies such as SearchStrategyLog to define its execution logic

Returns:

boolean

setImpl

void setImpl(java.lang.Object impl)

Sets the name of this strategy.

Parameters:

name - the name for this strategy.

setObject

void setObject(java.lang.Object obj)

This method may be used to attach a business object to this object.

Parameters:

obj - the business object being attached.

setType

void setType(SearchStrategy.SearchStrategyType type)

Sets a type of this Search Strategy
