withTemplateParameters

public Traverson.TraversalBuilder withTemplateParameters(Map<String,Object> parameters)

Adds the given operations parameters to the traversal. If a link discovered by the traversal is templated, the given parameters will be used to expand the operations into a resolvable URI.

Parameters:

parameters - can be null.

Returns:

withHeaders

public Traverson.TraversalBuilder withHeaders(org.springframework.http.HttpHeaders headers)

The HttpHeaders that shall be used for the requests of the traversal.

Parameters:

headers - can be null.

Returns:

toObject

public <T> T toObject(Class<T> type)

Executes the traversal and marshals the final response into an object of the given type.

Parameters:

type - must not be null.

Returns:

toObject

public <T> T toObject(org.springframework.core.ParameterizedTypeReference<T> type)

Executes the traversal and marshals the final response into an object of the given ParameterizedTypeReference.

Parameters:

type - must not be null.

Returns:

toObject

public <T> T toObject(String jsonPath)

Executes the traversal and returns the result of the given JSON Path expression evaluated against the final representation.

Parameters:

jsonPath - must not be null or empty.

Returns:

toEntity

public <T> org.springframework.http.ResponseEntity<T> toEntity(Class<T> type)

Returns the raw ResponseEntity with the representation unmarshalled into an instance of the given type.

Parameters:

type - must not be null.
