Class JsonSchema

java.lang.Object

com.github.fge.jsonschema.main.JsonSchema

@Immutable
public final class JsonSchema
extends Object

Single-schema instance validator

This is the class you will use the most often. It is, in essence, a JsonValidator initialized with a single JSON Schema. Note however that this class still retains the ability to resolve JSON References.

It has no public constructors: you should use the appropriate methods in JsonSchemaFactory to obtain an instance of this class.

Method Detail

validate

public com.github.fge.jsonschema.core.report.ProcessingReport validate(JsonNode instance,
                                                                       boolean deepCheck)
                                                                throws com.github.fge.jsonschema.core.exceptions.ProcessingException

Validate an instance and return a processing report

Parameters:

instance - the instance to validate

deepCheck - validate children even if container (array, object) is invalid

Returns:

a processing report

Throws:

com.github.fge.jsonschema.core.exceptions.ProcessingException - a processing error occurred during validation

Since:

2.1.8

validate

public com.github.fge.jsonschema.core.report.ProcessingReport validate(JsonNode instance)
                                                                throws com.github.fge.jsonschema.core.exceptions.ProcessingException

Validate an instance and return a processing report

This calls validate(JsonNode, boolean) with false as a third argument.

Parameters:

instance - the instance to validate

Returns:

a processing report

Throws:

com.github.fge.jsonschema.core.exceptions.ProcessingException - a processing error occurred during validation

validateUnchecked

public com.github.fge.jsonschema.core.report.ProcessingReport validateUnchecked(JsonNode instance,
                                                                                boolean deepCheck)

Validate an instance and return a processing report (unchecked version)

Unchecked validation means that conditions which would normally cause the processing to stop with an exception are instead inserted into the resulting report.

Warning: this means that anomalous events like an unresolvable JSON Reference, or an invalid schema, are masked!

Parameters:

instance - the instance to validate

deepCheck - validate children even if container (array, object) is invalid

Returns:

a report (a ListProcessingReport if an exception was thrown during processing)

Since:

2.1.8

See Also:

ProcessingResult.uncheckedResult(Processor, ProcessingReport, MessageProvider), JsonValidator.validate(JsonNode, JsonNode, boolean)

validateUnchecked

public com.github.fge.jsonschema.core.report.ProcessingReport validateUnchecked(JsonNode instance)

Validate an instance and return a processing report (unchecked version)

This calls validateUnchecked(JsonNode, boolean) with false as a third argument.

Parameters:

instance - the instance to validate

Returns:

a report (a ListProcessingReport if an exception was thrown during processing)

validInstance

public boolean validInstance(JsonNode instance)
                      throws com.github.fge.jsonschema.core.exceptions.ProcessingException

Check whether an instance is valid against this schema

Parameters:

instance - the instance

Returns:

true if the instance is valid

Throws:

com.github.fge.jsonschema.core.exceptions.ProcessingException - an error occurred during processing

validInstanceUnchecked

public boolean validInstanceUnchecked(JsonNode instance)

Check whether an instance is valid against this schema (unchecked version)

The same warnings apply as described in validateUnchecked(JsonNode).

Parameters:

instance - the instance to validate

Returns:

true if the instance is valid
