Annotation Type Depends

@Retention(value=RUNTIME)
 @Target(value={FIELD,METHOD})
public @interface Depends

Declares that a property depends on other one(s).

Applies to properties.

OpenXava uses this info in order to know when to recalculate values of a property in the user interface.
Example:

  @Depends("unitPrice")    
  public BigDecimal getUnitPriceInPesetas() {
    if (unitPrice == null) return null;
    return unitPrice.multiply(new BigDecimal("166.386")).setScale(0, BigDecimal.ROUND_HALF_UP);
  }
 

In this case if the unitPrice changes in the user interface, the value of unitPriceInPesetas is recalculated and redisplayed.
