Method Summary

Modifier and Type	Method and Description
Predicate	containsAnyOf(Collection<T> possibleCandidates) Builds a predicate which tests that the value of this operand contains any of the given possibleCandidates.
Predicate	containsAnyOf(T possibleCandidate) Builds a predicate which tests that the value of this operand contains the given possibleCandidate.
Predicate	containsAnyOf(T possibleCandidate1, T possibleCandidate2) Builds a predicate which tests that the value of this operand contains the given possibleCandidate1 or possibleCandidate2.
Predicate	containsAnyOf(T possibleCandidate1, T possibleCandidate2, T possibleCandidate3) Builds a predicate which tests that the value of this operand contains the given possibleCandidate1, possibleCandidate2, or possibleCandidate3
Predicate	containsAnyOf(T possibleCandidate1, T possibleCandidate2, T possibleCandidate3, T... morePossibleCandidates) Builds a predicate which tests that the value of this operand contains the given possibleCandidate1, possibleCandidate2, possibleCandidate3, or any of morePossibleCandidates.
Predicate	isEmpty() Builds a predicate which tests that the value of this operand contains no candidates.

Constructor Detail

CandidateOperand

public CandidateOperand(IdentityLinkType linkType)

Creates a new operand instance.

Parameters:

linkType - the type of identity links for all predicates to be built

Method Detail

containsAnyOf

public Predicate containsAnyOf(T possibleCandidate)

Builds a predicate which tests that the value of this operand contains the given possibleCandidate.

Parameters:

possibleCandidate - the expected candidate

Returns:

the new predicate instance

containsAnyOf

public Predicate containsAnyOf(T possibleCandidate1,
                               T possibleCandidate2)

Builds a predicate which tests that the value of this operand contains the given possibleCandidate1 or possibleCandidate2.

Parameters:

possibleCandidate1 - the first possible candidate

possibleCandidate2 - the second possible candidate

Returns:

the new predicate instance

containsAnyOf

public Predicate containsAnyOf(T possibleCandidate1,
                               T possibleCandidate2,
                               T possibleCandidate3)

Builds a predicate which tests that the value of this operand contains the given possibleCandidate1, possibleCandidate2, or possibleCandidate3

Parameters:

possibleCandidate1 - the first possible candidate

possibleCandidate2 - the second possible candidate

possibleCandidate3 - the third possible candidate

Returns:

the new predicate instance

containsAnyOf

public Predicate containsAnyOf(T possibleCandidate1,
                               T possibleCandidate2,
                               T possibleCandidate3,
                               T... morePossibleCandidates)

Builds a predicate which tests that the value of this operand contains the given possibleCandidate1, possibleCandidate2, possibleCandidate3, or any of morePossibleCandidates.

Parameters:

possibleCandidate1 - the first possible candidate

possibleCandidate2 - the second possible candidate

possibleCandidate3 - the third possible candidate

morePossibleCandidates - more possible candidates

Returns:

the new predicate instance

containsAnyOf

public Predicate containsAnyOf(Collection<T> possibleCandidates)

Builds a predicate which tests that the value of this operand contains any of the given possibleCandidates.

Parameters:

possibleCandidates - the possible candidates (tested with OR semantics)

Returns:

the new predicate instance

isEmpty

public Predicate isEmpty()

Builds a predicate which tests that the value of this operand contains no candidates.

Returns:

the new predicate instance
