All Implemented Interfaces:

public class SimpleAttributePredicate
extends AbstractAttributePredicate

Predicate that evaluates an AttributeContext and checks for particular attribute/value pairs.

A map to a collection of strings is used to represent the attribute(s) and value(s) to evaluate. The values are evaluated as a disjunction (OR) and the attributes are evaluated as a conjunction (AND).

This handles only simple string-valued data.

For the special case of checking for an attribute's presence, regardless of values, the '*' value is supported. Note that this does NOT exclude pathological cases such as empty or null values. A more advanced predicate should be used to deal with such cases.

Method Detail

setAttributeValueMap

public void setAttributeValueMap(@Nonnull@NonnullElements
                        Map<String,Collection<String>> map)

Set the map of attribute/value pairs (as a map of string collections) to check for.

Parameters:

map - map of attribute/value pairs

allowNullAttributeContext

protected boolean allowNullAttributeContext()

Get the result of the predicate in the case the attribute context is null.

Overrides:

allowNullAttributeContext in class AbstractAttributePredicate

Returns:

null context result

hasMatch

protected boolean hasMatch(Map<String,IdPAttribute> attributeMap)

Abstract implementation of the condition to evaluate.

Specified by:

hasMatch in class AbstractAttributePredicate

Parameters:

attributeMap - the attributes to evaluate

Returns:

the condition result

findMatch

protected boolean findMatch(@Nonnull@NotEmpty
                String toMatch,
                @Nonnull
                IdPAttribute attribute)

Look for a matching value in an attribute.

Parameters:

toMatch - value to look for

attribute - attribute to check

Returns:

true iff the value is one of the attribute's values
