getCachePath

public String getCachePath(ImageGenerator<ParameterProvider<P>> generator,
                           ParameterProvider<P> parameterProvider)

Description copied from interface: CachingStrategy

Returns a unique path pertinent to the given generator and parameter to use for storing the generated image. Returns null if the implementation determines caching should not occur.

Specified by:

shouldRegenerate

@Deprecated
public boolean shouldRegenerate(info.magnolia.cms.core.NodeData cachedBinary,
                                            ParameterProvider<P> parameterProvider)

Deprecated. since 3.3 - use shouldRegenerate(Property, ParameterProvider) instead.

shouldRegenerate

public boolean shouldRegenerate(javax.jcr.Property cachedBinary,
                                ParameterProvider<P> parameterProvider)

The default implementation simply delegates this decision to ParameterProvider.

Specified by:

shouldRegenerate in interface CachingStrategy<P>

Returns:

true if the image should be regenerated.
