Detailed Description

<font size="-1" color="#FF0000">**For internal use only** </font> A version of IndexedPropertySupport that caches the property value to avoid that the underlying Bean has to handle bursts of getValue() calls. The caching strategy is given at construction time.

Object cern::gp::nodes::impl::CacheableIndexedPropertySupport::getIndexedValue

(

int

index

)

throws IllegalAccessException, IllegalArgumentException, InvocationTargetException [inline]

overrides getIndexedValue, and caches the value

References cachedValue, cachingStrategy, cern::gp::nodes::cache::CachingStrategy::isCacheValid(), and cern::gp::nodes::cache::CachingStrategy::validateCache().

PropertyEditor cern::gp::nodes::impl::CacheableIndexedPropertySupport::getPropertyEditor

(

)

[inline]

Returns an instance of property editor for this property. The implementation reconizes a special type of PropertyEditor that implements cern.gp.beans.BeanDependentPropertyEditor and invoke their initialization method.

Returns:

the property editor or null if there should not be any editor.
