Method Details

checkMisconfigured

public void checkMisconfigured(BeanInstanceMap defaultInstances)
                        throws BeanMisconfiguredException

Description copied from class: AnchorBean

Checks that a bean's properties conform to expectations.

Overrides:

checkMisconfigured in class AnchorBean<Feature<FeatureInputStack>>

Parameters:

defaultInstances - all available default instances if the DefaultInstance annotation is used

Throws:

BeanMisconfiguredException - if the bean has not been configured properly as XML

describeParameters

public String describeParameters()

Description copied from class: Feature
