metadata - the meta data

Returns:

if the item should be skipped

shouldSkip

public boolean shouldSkip(AnnotatedTypeMetadata metadata,
                          ConfigurationCondition.ConfigurationPhase phase)

Determine if an item should be skipped based on @Conditional annotations.

Parameters:

metadata - the meta data

phase - the phase of the call

Returns:

if the item should be skipped
