Method Summary

Modifier and Type	Method and Description
PatternsRequestCondition	combine(PatternsRequestCondition other) Returns a new instance with URL patterns from the current instance ("this") and the "other" instance as follows: If there are patterns in both instances, combine the patterns in "this" with the patterns in "other" using PathPattern.combine(PathPattern).

Set<String>	getDirectPaths() Return the mapping paths that are not patterns.
PatternsRequestCondition	getMatchingCondition(ServerWebExchange exchange) Checks if any of the patterns match the given request and returns an instance that is guaranteed to contain matching patterns, sorted.
Set<PathPattern>	getPatterns()

Constructor Detail

PatternsRequestCondition

public PatternsRequestCondition(PathPattern... patterns)

Creates a new instance with the given URL patterns.

Parameters:

patterns - 0 or more URL patterns; if 0 the condition will match to every request.

PatternsRequestCondition

public PatternsRequestCondition(List<PathPattern> patterns)

Creates a new instance with the given URL patterns.

Method Detail

getPatterns

public Set<PathPattern> getPatterns()

getContent

protected Collection<PathPattern> 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<PatternsRequestCondition>

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<PatternsRequestCondition>

getDirectPaths

public Set<String> getDirectPaths()

Return the mapping paths that are not patterns.

Since:

5.3

combine

public PatternsRequestCondition combine(PatternsRequestCondition other)

Returns a new instance with URL patterns from the current instance ("this") and the "other" instance as follows:

• If there are patterns in both instances, combine the patterns in "this" with the patterns in "other" using PathPattern.combine(PathPattern).
• If only one instance has patterns, use them.
• If neither instance has patterns, use an empty String (i.e. "").

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 PatternsRequestCondition getMatchingCondition(ServerWebExchange exchange)

Checks if any of the patterns match the given request and returns an instance that is guaranteed to contain matching patterns, sorted.

Parameters:

exchange - the current exchange

Returns:

the same instance if the condition contains no patterns; or a new condition with sorted matching patterns; or null if no patterns match.

compareTo

public int compareTo(PatternsRequestCondition other,
                     ServerWebExchange exchange)

Compare the two conditions based on the URL patterns they contain. Patterns are compared one at a time, from top to bottom. If all compared patterns match equally, but one instance has more patterns, it is considered a closer match.

It is assumed that both instances have been obtained via getMatchingCondition(ServerWebExchange) to ensure they contain only patterns that match the request and are sorted with the best matches on top.
