Constructor Detail

RequiredIfOthersPresent

public RequiredIfOthersPresent(String propertyName,
                               String[] otherPropertyNames)

Tests that the property is required if all "other properties" are present. Present means they are "non null."

Parameters:

otherPropertyNames - to test

RequiredIfOthersPresent

public RequiredIfOthersPresent(String propertyName,
                               String[] otherPropertyNames,
                               LogicalOperator operator)

Tests that the property is required if "other properties" are present. Present means they are "non null." The operator parameter determines how the set of other property names is handled. If AND, then all must be present before the primary proeprty will be required. If OR, then if any of the other properties are present, then the primary property will be required. the logical operator, either AND or OR.

Parameters:

otherPropertyNames - to test

operator - Either AND or OR.

RequiredIfOthersPresent

public RequiredIfOthersPresent(String propertyName,
                               String otherPropertyNames)

Tests that the property is required if all "other properties" are present. Present means they are "non null."

Parameters:

otherPropertyNames - one or more other properties, delimited by commas.

                               LogicalOperator operator)

Tests that the property is required if all or any of the "other properties" are present.

Parameters:

otherPropertyNames - one or more other properties, delimited by commas.

operator - the logical operator, either AND or OR.

Method Detail

isDependentOn

public boolean isDependentOn(String propertyName)

Description copied from class: RequiredIfTrue

Determine if this rule is dependent on the given property name. True if either the direct poperty (from the contstructor) is equal to the given name, or if the "if true" predicate is a PropertyConstraint and it is dependent on the given property.

Specified by:

isDependentOn in interface PropertyConstraint

Overrides:

isDependentOn in class RequiredIfTrue

Returns:

true if this rule is dependent on the given property

isCompoundRule

public boolean isCompoundRule()

Description copied from interface: PropertyConstraint

Does this property constraint effect more than one property?

Specified by:

isCompoundRule in interface PropertyConstraint

Overrides:

isCompoundRule in class AbstractPropertyConstraint

Returns:

true if yes, false otherwise
