Class HeadersRequestCondition

Constructor Detail

• HeadersRequestCondition

  public HeadersRequestCondition​(String... headers)

  Create a new instance from the given header expressions. Expressions with header names 'Accept' or 'Content-Type' are ignored. See ConsumesRequestCondition and ProducesRequestCondition for those.

  Parameters:

  headers - media type expressions with syntax defined in RequestMapping.headers(); if 0, the condition will match to every request

Method Detail

• getExpressions

  public Set<NameValueExpression<String>> getExpressions()

  Return the contained request header expressions.

• getContent

  protected Collection<org.springframework.web.reactive.result.condition.HeadersRequestCondition.HeaderExpression> getContent()

  Description copied from class: AbstractRequestCondition
  Return the discrete items a request condition is composed of.

  For example URL patterns, HTTP request methods, param expressions, etc.

  Specified by:

  getContent in class AbstractRequestCondition<HeadersRequestCondition>

  Returns:

  a collection of objects (never null)

• getToStringInfix

  protected String getToStringInfix()

  Description copied from class: AbstractRequestCondition
  The notation to use when printing discrete items of content.

  For example " || " for URL patterns or " && " for param expressions.

  Specified by:

  getToStringInfix in class AbstractRequestCondition<HeadersRequestCondition>

• combine

  public HeadersRequestCondition combine​(HeadersRequestCondition other)

  Returns a new instance with the union of the header expressions from "this" and the "other" instance.

  Parameters:

  other - the condition to combine with.

  Returns:

  a request condition instance that is the result of combining the two condition instances.

• getMatchingCondition

  @Nullable
  public HeadersRequestCondition getMatchingCondition​(ServerWebExchange exchange)

  Returns "this" instance if the request matches all expressions; or null otherwise.

  Returns:

  a condition instance in case of a match or null otherwise.

• compareTo

  public int compareTo​(HeadersRequestCondition other,
                       ServerWebExchange exchange)

  Compare to another condition based on header expressions. A condition is considered to be a more specific match, if it has:

  1. A greater number of expressions.
  2. A greater number of non-negated expressions with a concrete value.

  It is assumed that both instances have been obtained via getMatchingCondition(ServerWebExchange) and each instance contains the matching header expression only or is otherwise empty.
