Method Detail

_deserialize

protected Object _deserialize(String value,
                              DeserializationContext ctxt)
                       throws IOException

Description copied from class: FromStringDeserializer

Main method from trying to deserialize actual value from non-empty String.

Specified by:

_deserialize in class FromStringDeserializer<Object>

Throws:

IOException

getEmptyValue

public Object getEmptyValue(DeserializationContext ctxt)
                     throws JsonMappingException

Description copied from class: JsonDeserializer

Method called to determine value to be used for "empty" values (most commonly when deserializing from empty JSON Strings). Usually this is same as JsonDeserializer.getNullValue(com.fasterxml.jackson.databind.DeserializationContext) (which in turn is usually simply Java null), but it can be overridden for specific types. Or, if type should never be converted from empty String, method can also throw an exception.

This method may be called once, or multiple times, depending on what JsonDeserializer.getEmptyAccessPattern() returns.

Default implementation simply calls JsonDeserializer.getNullValue(com.fasterxml.jackson.databind.DeserializationContext) and returns value.

Overrides:

getEmptyValue in class JsonDeserializer<Object>

Throws:

JsonMappingException

_deserializeFromEmptyStringDefault

protected Object _deserializeFromEmptyStringDefault(DeserializationContext ctxt)
                                             throws IOException

Overrides:

_deserializeFromEmptyStringDefault in class FromStringDeserializer<Object>

Throws:

IOException

_shouldTrim

protected boolean _shouldTrim()

Overrides:

_shouldTrim in class FromStringDeserializer<Object>

_firstHyphenOrUnderscore

protected int _firstHyphenOrUnderscore(String str)
