Class PropertyVariableInterpolator

java.lang.Object
  wicket.util.string.interpolator.VariableInterpolator
      wicket.util.string.interpolator.PropertyVariableInterpolator

public final class PropertyVariableInterpolator
extends VariableInterpolator

Interpolates values into strings that are produced by interpreting property expressions against a beans model.

The interpolate(String string, Object model) method takes a string such as "My name is ${name}" and a beans model such as a Person, and reflects on the object using any property expressions found inside ${} markers in the string. In this case, if the Person model had a getName() method, the results of calling that method would be substituted for ${name}. If getName() returned Jonathan, interpolate() would then return "My name is Jonathan".
