Method Details

getNamedBean

NamedBeanHandle<?> getNamedBean()

getBean

public NamedBean getBean()

getType

public int getType()

getPropertyName

public String getPropertyName()

getVarType

public Conditional.Type getVarType()

getDevName

public String getDevName()

addConditional

setEnabled

public void setEnabled(boolean state)

calculateClient

public void calculateClient(int idx,
 PropertyChangeEvent evt)

propertyChange

public void propertyChange(PropertyChangeEvent evt)

When _enabled is false, Conditional.calculate will compute the state of the conditional, but will not trigger its actions. When _enabled is true, Conditional.calculates its state and trigger its actions if its state has changed.
