/**
|
82 |
* Defines the properties of a collection of Features, as a result of a query
|
83 |
* through a FeatureStore.
|
84 |
*
|
85 |
* A FeatureQuery is always defined by a FeatureType, or by the list of
|
86 |
* attribute names of the FeatureStore to return.
|
87 |
*
|
88 |
* The filter allows to select Features whose properties have values with the
|
89 |
* characteristics defined by the filter.
|
90 |
*
|
91 |
* The order is used to set the order of the result FeatureCollection, based on
|
92 |
* the values of the properties of the Features.
|
93 |
*
|
94 |
* The scale parameter can be used by the FeatureStore as a hint about the
|
95 |
* quality or resolution of the data needed to view or operate with the data
|
96 |
* returned. As an example, the FeatureStore may use the scale to return only a
|
97 |
* representative subset of the data, or maybe to return Features with less
|
98 |
* detail, like a point or a line instead of a polygon.
|
99 |
*
|
100 |
* If an implementation of FeatureStore is able to get other parameters to
|
101 |
* customize the behavior of the getDataCollection methods, there is an option
|
102 |
* to set more parameters through the setAttribute method.
