Method Detail

isMethodMatch

public boolean isMethodMatch(@NonNull
                             io.micronaut.inject.ast.MethodElement methodElement,
                             @NonNull
                             MatchContext matchContext)

Checks whether the given method is a match.

Specified by:

isMethodMatch in interface MethodCandidate

Overrides:

isMethodMatch in class AbstractPatternBasedMethod

Parameters:

methodElement - The method element

matchContext -

Returns:

True if it is

hasQueryAnnotation

protected boolean hasQueryAnnotation(@NonNull
                                     io.micronaut.inject.ast.MethodElement methodElement)

Method that checks for the presence of the query annotation.

Parameters:

methodElement - The method element

Returns:

True if a query annotation is present

buildMatchInfo

public MethodMatchInfo buildMatchInfo(@NonNull
                                      MethodMatchContext matchContext)

Description copied from interface: MethodCandidate

Builds the method info. The method MethodCandidate.isMethodMatch(MethodElement, MatchContext) should be invoked and checked prior to calling this method.

Specified by:

buildMatchInfo in interface MethodCandidate

Parameters:

matchContext - The match context

Returns:

The method info or null if it cannot be built. If the method info cannot be built an error will be reported to the passed MethodMatchContext
