StructuredBindingEditors convert structured data in a Map into an object. Typically a structured editor will pull several values out of the Map that are necessary to initialize the state of the object.
class Address {
String state
String city
}
class StructuredAddressBindingEditor implements StructuredBindingEditor {
public Object getPropertyValue(Object obj, String propertyName, Map source) {
def address = new Address()
address.state = source[propertyName + '_someState']
address.city = source[propertyName + '_someCity']
address
}
}
def binder = new SimpleDataBinder()
binder.registerStructuredEditor Address, new StructuredAddressBindingEditor()
def resident = new Resident()
def bindingSource = [:]
bindingSource.name = 'Scott'
bindingSource.homeAddress_someCity = "Scott's Home City"
bindingSource.homeAddress_someState = "Scott's Home State"
bindingSource.workAddress_someState = "Scott's Work State"
bindingSource.workAddress = 'struct'
bindingSource.homeAddress = 'struct'
binder.bind resident, bindingSource
resident.name == 'Scott'
resident.homeAddress
assert resident.homeAddress.city == "Scott's Home City"
assert resident.homeAddress.state == "Scott's Home State"
assert resident.workAddress
assert resident.workAddress.state == "Scott's Work State"
assert resident.workAddress.city == null
