Constructor Detail

EvidenceVerifyCallback

public EvidenceVerifyCallback(Evidence evidence)

Construct a new instance of this Callback.

Parameters:

evidence - the evidence to be verified

Method Detail

getEvidence

public Evidence getEvidence()

Get the evidence being verified.

Returns:

the evidence being verified

getEvidence

public <C extends Evidence> C getEvidence(Class<C> evidenceType)

Get the acquired evidence, if it is set and of the given type, and if so, return the evidence cast to the type.

Type Parameters:

C - the evidence type

Parameters:

evidenceType - the evidence type class (must not be null)

Returns:

the evidence, or null if the criteria wasn't met

getEvidence

public <C extends Evidence> C getEvidence(Class<C> evidenceType,
                                          String algorithmName)

Get the acquired evidence, if it is set and of the given type and algorithm, and if so, return the evidence cast to the type.

Type Parameters:

C - the evidence type

Parameters:

evidenceType - the evidence type class (must not be null)

algorithmName - the algorithm name

Returns:

the evidence, or null if the criteria are not met

applyToEvidence

public <C extends Evidence,R> R applyToEvidence(Class<C> evidenceType,
                                                      Function<C,R> function)

Apply the given function to the acquired evidence, if it is set and of the given type.

Type Parameters:

C - the evidence type

R - the return type

Parameters:

evidenceType - the evidence type class (must not be null)

function - the function to apply (must not be null)

Returns:

the result of the function, or null if the criteria are not met

applyToEvidence

public <C extends Evidence,R> R applyToEvidence(Class<C> evidenceType,
                                                      String algorithmName,
                                                      Function<C,R> function)

Apply the given function to the acquired evidence, if it is set and of the given type and algorithm.

Type Parameters:

C - the evidence type

R - the return type

Parameters:

evidenceType - the evidence type class (must not be null)

algorithmName - the algorithm name

function - the function to apply (must not be null)

Returns:

the result of the function, or null if the criteria are not met

setVerified

public void setVerified(boolean verified)

Set if the evidence referenced here has been verified.

Parameters:

verified - the verification state of the evidence

isVerified

public boolean isVerified()

Get the verification state for the evidence referenced here.

Returns:

true if the evidence has been verified, false otherwise

isOptional

public boolean isOptional()

This Callback is not optional as verification is required.

Specified by:

isOptional in interface ExtendedCallback

Returns:

true if the callback is optional, false if it is mandatory

needsInformation

public boolean needsInformation()

This Callback needs to know if evidence validation was successful.

Specified by:

needsInformation in interface ExtendedCallback

Returns:

true if the callback is requesting information, false if it is only providing information
