/**
Applies a schema to an array of data located in a JSON structure, returning
a normalized object with results in the `results` property. Additional
information can be parsed out of the JSON for inclusion in the `meta`
property of the response object. If an error is encountered during
processing, an `error` property will be added.
The input _data_ is expected to be an object or array. If it is a string,
it will be passed through `Y.JSON.parse()`.
If _data_ contains an array of data records to normalize, specify the
_schema.resultListLocator_ as a dot separated path string just as you would
reference it in JavaScript. So if your _data_ object has a record array at
_data.response.results_, use _schema.resultListLocator_ =
"response.results". Bracket notation can also be used for array indices or
object properties (e.g. "response['results']"); This is called a "path
locator"
Field data in the result list is extracted with field identifiers in
_schema.resultFields_. Field identifiers are objects with the following
properties:
* `key` : <strong>(required)</strong> The path locator (String)
* `parser`: A function or the name of a function on `Y.Parsers` used
to convert the input value into a normalized type. Parser
functions are passed the value as input and are expected to
return a value.
If no value parsing is needed, you can use path locators (strings)
instead of field identifiers (objects) -- see example below.
If no processing of the result list array is needed, _schema.resultFields_
can be omitted; the `response.results` will point directly to the array.
If the result list contains arrays, `response.results` will contain an
array of objects with key:value pairs assuming the fields in
_schema.resultFields_ are ordered in accordance with the data array
values.
If the result list contains objects, the identified _schema.resultFields_
will be used to extract a value from those objects for the output result.
To extract additional information from the JSON, include an array of
path locators in _schema.metaFields_. The collected values will be
stored in `response.meta`.
@example
// Process array of arrays
var schema = {
resultListLocator: 'produce.fruit',
resultFields: [ 'name', 'color' ]
},
data = {
produce: {
fruit: [
[ 'Banana', 'yellow' ],
[ 'Orange', 'orange' ],
[ 'Eggplant', 'purple' ]
]
}
};
var response = Y.DataSchema.JSON.apply(schema, data);
// response.results[0] is { name: "Banana", color: "yellow" }
// Process array of objects + some metadata
schema.metaFields = [ 'lastInventory' ];
data = {
produce: {
fruit: [
{ name: 'Banana', color: 'yellow', price: '1.96' },
{ name: 'Orange', color: 'orange', price: '2.04' },
{ name: 'Eggplant', color: 'purple', price: '4.31' }
]
},
lastInventory: '2011-07-19'
};
response = Y.DataSchema.JSON.apply(schema, data);
// response.results[0] is { name: "Banana", color: "yellow" }
// response.meta.lastInventory is '2001-07-19'
// Use parsers
schema.resultFields = [
{
key: 'name',
parser: function (val) { return val.toUpperCase(); }
},
{
key: 'price',
parser: 'number' // Uses Y.Parsers.number
}
];
response = Y.DataSchema.JSON.apply(schema, data);
// Note price was converted from a numeric string to a number
// response.results[0] looks like { fruit: "BANANA", price: 1.96 }
