Class JsonSchemaFactory

java.lang.Object

com.github.fge.jsonschema.main.JsonSchemaFactory

All Implemented Interfaces:

Frozen<JsonSchemaFactoryBuilder>

@Immutable
public final class JsonSchemaFactory
extends Object
implements Frozen<JsonSchemaFactoryBuilder>

The main validator provider

From an instance of this factory, you can obtain the following:

• a SyntaxValidator, to validate schemas;
• a JsonValidator, to validate an instance against a schema;
• a JsonSchemaImpl, to validate instances against a fixed schema.

Method Detail

byDefault

public static JsonSchemaFactory byDefault()

Return a default factory

This default factory has validators for both draft v4 and draft v3. It defaults to draft v4.

Returns:

a factory with default settings

JsonSchemaFactoryBuilder.JsonSchemaFactoryBuilder()

newBuilder

public static JsonSchemaFactoryBuilder newBuilder()

Return a factory builder

Returns:

a JsonSchemaFactoryBuilder

getValidator

public JsonValidator getValidator()

Return the main schema/instance validator provided by this factory

Returns:

a JsonValidator

getSyntaxValidator

public SyntaxValidator getSyntaxValidator()

Return the syntax validator provided by this factory

Returns:

a SyntaxValidator

getJsonSchema

public JsonSchema getJsonSchema(JsonNode schema)
                         throws ProcessingException

Build an instance validator tied to a schema

Note that the validity of the schema is not checked. Use getSyntaxValidator() if you are not sure.

Parameters:

schema - the schema

Returns:

a JsonSchema

Throws:

ProcessingException - schema is a MissingNode

NullPointerException - schema is null

getJsonSchema

public JsonSchema getJsonSchema(JsonNode schema,
                                String ptr)
                         throws ProcessingException

Build an instance validator tied to a subschema from a main schema

Note that the validity of the schema is not checked. Use getSyntaxValidator() if you are not sure.

Parameters:

schema - the schema

ptr - a JSON Pointer as a string

Returns:

a JsonSchema

Throws:

ProcessingException - ptr is not a valid JSON Pointer, or resolving the pointer against the schema leads to a MissingNode

NullPointerException - schema is null, or pointer is null

getJsonSchema

public JsonSchema getJsonSchema(String uri)
                         throws ProcessingException

Build an instance validator out of a schema loaded from a URI

Parameters:

uri - the URI

Returns:

a JsonSchema

Throws:

ProcessingException - failed to load from this URI

NullPointerException - URI is null

getProcessor

public Processor<FullData,FullData> getProcessor()

Return the raw validation processor

This will allow you to chain the full validation processor with other processors of your choice. Useful if, for instance, you wish to add post checking which JSON Schema cannot do by itself.

Returns:

the processor.

thaw

public JsonSchemaFactoryBuilder thaw()

Return a thawed instance of that factory

Specified by:

thaw in interface Frozen<JsonSchemaFactoryBuilder>

Returns:

a JsonSchemaFactoryBuilder
