Field Detail

instance

public static final StringArraySerializer instance

_elementSerializer

protected final JsonSerializer<Object> _elementSerializer
Value serializer to use, if it's not the standard one (if it is we can optimize serialization a lot)

Constructor Detail

StringArraySerializer

protected StringArraySerializer()

StringArraySerializer

public StringArraySerializer(StringArraySerializer src,
                             BeanProperty prop,
                             JsonSerializer<?> ser)
Method Detail

_withValueTypeSerializer

public ContainerSerializer<?> _withValueTypeSerializer(TypeSerializer vts)
Strings never add type info; hence, even if type serializer is suggested, we'll ignore it...

Specified by:
_withValueTypeSerializer in class ContainerSerializer<String[]>

createContextual

public JsonSerializer<?> createContextual(SerializerProvider provider,
                                          BeanProperty property)
                                   throws JsonMappingException
Description copied from interface: ContextualSerializer
Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property. Note that instance that this method is called on is typically shared one and as a result method should NOT modify this instance but rather construct and return a new instance. This instance should only be returned as-is, in case it is already suitable for use.

Specified by:
createContextual in interface ContextualSerializer
Parameters:
provider - Serializer provider to use for accessing config, other serializers
property - Method or field that represents the property (and is used to access value to serialize). Should be available; but there may be cases where caller can not provide it and null is passed instead (in which case impls usually pass 'this' serializer as is)
Returns:
Serializer to use for serializing values of specified property; may be this instance or a new instance.
Throws:
JsonMappingException

getContentType

public JavaType getContentType()
Description copied from class: ContainerSerializer
Accessor for finding declared (static) element type for type this serializer is used for.

Specified by:
getContentType in class ContainerSerializer<String[]>

getContentSerializer

public JsonSerializer<?> getContentSerializer()
Description copied from class: ContainerSerializer
Accessor for serializer used for serializing contents (List and array elements, Map values etc) of the container for which this serializer is used, if it is known statically. Note that for dynamic types this may return null; if so, caller has to instead use ContainerSerializer.getContentType() and SerializerProvider.findValueSerializer(java.lang.Class, com.fasterxml.jackson.databind.BeanProperty).

Specified by:
getContentSerializer in class ContainerSerializer<String[]>

isEmpty

public boolean isEmpty(String[] value)
Description copied from class: JsonSerializer
Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).

Default implementation will consider only null values to be empty.

Specified by:
isEmpty in class ContainerSerializer<String[]>

hasSingleElement

public boolean hasSingleElement(String[] value)
Description copied from class: ContainerSerializer
Method called to determine if the given value (of type handled by this serializer) contains exactly one element.

Note: although it might seem sensible to instead define something like "getElementCount()" method, this would not work well for containers that do not keep track of size (like linked lists may not).

Specified by:
hasSingleElement in class ContainerSerializer<String[]>

serializeContents

public void serializeContents(String[] value,
                              com.fasterxml.jackson.core.JsonGenerator jgen,
                              SerializerProvider provider)
                       throws IOException,
                              com.fasterxml.jackson.core.JsonGenerationException
Specified by:
serializeContents in class ArraySerializerBase<String[]>
Throws:
IOException
com.fasterxml.jackson.core.JsonGenerationException

getSchema

public JsonNode getSchema(SerializerProvider provider,
                          Type typeHint)
Description copied from class: StdSerializer
Default implementation simply claims type is "string"; usually overriden by custom serializers.

Specified by:
getSchema in interface SchemaAware
Overrides:
getSchema in class StdSerializer<String[]>
Parameters:
provider - The serializer provider.
typeHint - A hint about the type.
Returns:
Json-schema for this serializer.
