Method Detail

init

public void init(Operator operator)
          throws UserError

Description copied from interface: AttributeFilterCondition

Initializes the condition before checking anything. If checking depends on parameters, their values might be retrieved in this method.

Specified by:

init in interface AttributeFilterCondition

Overrides:

init in class AbstractAttributeFilterCondition

Throws:

UserError

beforeScanCheck

public AttributeFilterCondition.ScanResult beforeScanCheck(Attribute attribute)
                                                    throws UserError

Description copied from interface: AttributeFilterCondition

This method initializes this condition and resets all counters. It returns REMOVE, if the attribute can be removed without checking examples. If it has been removed, no checking during examples will occur. If it returns UNCHECKED, this Attribute Filter needs a full check and hence the attribute cannot be deleted or kept. Distinguishing this is important, because of the inverting, which otherwise might remove attributes although they only have been kept for later checking.

Parameters:

attribute - this is the attribute, the filter will have to check for.

Throws:

UserError

getParameterTypes

public java.util.List<ParameterType> getParameterTypes(Operator operator)

Description copied from class: AbstractAttributeFilterCondition

Just returns an empty list. Subclasses might add parameters

Specified by:

getParameterTypes in interface AttributeFilterCondition

Overrides:

getParameterTypes in class AbstractAttributeFilterCondition
