resolve

public static java.lang.Object resolve(java.lang.String variableName,

resolve the value of variableName

Parameters:

variableName - Description of the Parameter

bindings - Description of the Parameter

Returns:

the value of variableName or null if undefined. it the variableName points to a ISlot, the ISlot.getSlotValue() is returned.
