Modifier and Type	Method and Description
Set<ValidationMessage>	validate(com.fasterxml.jackson.databind.JsonNode rootNode) Validate the given root JsonNode, starting at the root of the data path.
Set<ValidationMessage>	validate(com.fasterxml.jackson.databind.JsonNode node, com.fasterxml.jackson.databind.JsonNode rootNode, String at) Validate the given JsonNode, the given node is the child node of the root node at given data path.
Set<ValidationMessage>	walk(com.fasterxml.jackson.databind.JsonNode node, com.fasterxml.jackson.databind.JsonNode rootNode, String at, boolean shouldValidateSchema) This method gives the capability to walk through the given JsonNode, allowing functionality beyond validation like collecting information,handling cross cutting concerns like logging or instrumentation.

Method Detail

validate

public Set<ValidationMessage> validate(com.fasterxml.jackson.databind.JsonNode rootNode)

Description copied from interface: JsonValidator

Validate the given root JsonNode, starting at the root of the data path.

Specified by:

validate in interface JsonValidator

Parameters:

rootNode - JsonNode

Returns:

A list of ValidationMessage if there is any validation error, or an empty list if there is no error.

validate

public Set<ValidationMessage> validate(com.fasterxml.jackson.databind.JsonNode node,
                                       com.fasterxml.jackson.databind.JsonNode rootNode,
                                       String at)

Description copied from interface: JsonValidator

Validate the given JsonNode, the given node is the child node of the root node at given data path.

Specified by:

validate in interface JsonValidator

Parameters:

node - JsonNode

rootNode - JsonNode

at - String

Returns:

A list of ValidationMessage if there is any validation error, or an empty list if there is no error.

walk

public Set<ValidationMessage> walk(com.fasterxml.jackson.databind.JsonNode node,
                                   com.fasterxml.jackson.databind.JsonNode rootNode,
                                   String at,
                                   boolean shouldValidateSchema)

Description copied from interface: JsonSchemaWalker

This method gives the capability to walk through the given JsonNode, allowing functionality beyond validation like collecting information,handling cross cutting concerns like logging or instrumentation. This method also performs the validation if shouldValidateSchema is set to true.

BaseJsonValidator.walk(JsonNode, JsonNode, String, boolean) provides a default implementation of this method. However validators that parse sub-schemas should override this method to call walk method on those sub-schemas.

Specified by:

walk in interface JsonSchemaWalker

Parameters:

node - JsonNode

rootNode - JsonNode

at - String

shouldValidateSchema - boolean

Returns:

a set of validation messages if shouldValidateSchema is true.
