/**
|
54 |
* Defines the properties of a collection of Features, as a result of a query
|
55 |
* through a FeatureStore.
|
56 |
* <p>
|
57 |
* A FeatureQuery is always defined by a FeatureType, or by the list of
|
58 |
* attribute names of the FeatureStore to return.
|
59 |
* </p>
|
60 |
* <p>
|
61 |
* The filter allows to select Features whose properties have values with the
|
62 |
* characteristics defined by the filter.
|
63 |
* </p>
|
64 |
* <p>
|
65 |
* The order is used to set the order of the result FeatureCollection, based on
|
66 |
* the values of the properties of the Features.
|
67 |
* </p>
|
68 |
* <p>
|
69 |
* The scale parameter can be used by the FeatureStore as a hint about the
|
70 |
* quality or resolution of the data needed to view or operate with the data
|
71 |
* returned. As an example, the FeatureStore may use the scale to return only a
|
72 |
* representative subset of the data, or maybe to return Features with less
|
73 |
* detail, like a point or a line instead of a polygon.
|
74 |
* </p>
|
75 |
* <p>
|
76 |
* If an implementation of FeatureStore is able to get other parameters to
|
77 |
* customize the behavior of the getDataCollection methods, there is an option
|
78 |
* to set more parameters through the setAttribute method.
|
