Checks based on the current ValidationContext.DiscriminatorContext whether the provided JsonSchema a match against against the current discriminator.

Parameters:

currentDiscriminatorContext - the currently active ValidationContext.DiscriminatorContext

discriminator - the discriminator to use for the check

discriminatorPropertyValue - the value of the discriminator/propertyName field

jsonSchema - the JsonSchema to check

registerAndMergeDiscriminator

protected static void registerAndMergeDiscriminator(ValidationContext.DiscriminatorContext currentDiscriminatorContext,
                                                    com.fasterxml.jackson.databind.node.ObjectNode discriminator,
