Class Feature.Builder
- All Implemented Interfaces:
AutoCloseable
- Enclosing class:
Feature
Feature
object.
Make sure to
- configure the
dataType()
before callingvalue()
- configure the
id()
anddataType()
before finishing theFeature
usingbuild()
Otherwise a java.lang.IllegalStateException will be thrown.

build
Build the feature using the settings configured.After this method is invoked once, this builder can no longer be used.
- Returns:
- the feature
- Throws:
IllegalStateException
- if the id or dataType are not configured
-
id
Configures the id of the feature being built.A feature id should be unique across a model.
This method is not mandatory, though Features in a model must have an id. It is allowed to temporarily have features without id, for example during
Feature
creation. As soon as such a temporaryFeature
isadded
to a model, it must beassigned
anid
though.When no id is set,
Feature#getId
will throw an exception.- Parameters:
id
- the id- Returns:
- this builder
-
resetId
Resets the id.Calling this method will cause the built
Feature
to have no id, thus throwing an exception when callingFeature#getId
.Features in a model must have an id. It is allowed to temporarily have features without id, for example during
Feature
creation. As soon as such a temporaryFeature
isadded
to a model, it must beassigned
anid
though.Note that for a newly created
Feature.Builder
using theFeature#newBuilder()
method, the id will be empty by default. This method is less useful in that case. It is mainly useful when using theFeature#asBuilder()
method.- Returns:
- this builder
- Since:
- 2023.1
-
dataType
Configures the dataType of the feature being built.- Parameters:
dataType
- the data type- Returns:
- this builder
-
value
@NotNull public <T> Feature.Builder value(@NotNull DataPropertyPath propertyPath, @NotNull T value) throws IllegalArgumentException Sets the value associated with the given property.Example
featureBuilder.value(booleanPropertyPath, booleanValue); featureBuilder.value(intPropertyPath, intValue); featureBuilder.value(longPropertyPath, longValue); featureBuilder.value(floatPropertyPath, floatValue); featureBuilder.value(doublePropertyPath, doubleValue); featureBuilder.value(stringPropertyPath, stringValue); featureBuilder.value(geometryPropertyPath, geometry);
- Type Parameters:
T
- the supported types arejava.lang.Boolean
,java.lang.Integer
,java.lang.Long
,java.lang.Float
,java.lang.Double
,java.lang.String
andGeometry
- Parameters:
propertyPath
- the property for which to set the valuevalue
- the value- Returns:
- this builder
- Throws:
IllegalArgumentException
- when the dataType has not been configured yet, the property is not of a known type, or if it doesn't exist in theDataType
.
-
resetValue
@NotNull public Feature.Builder resetValue(@NotNull DataPropertyPath propertyPath) throws IllegalArgumentException Resets the value associated with the given property.Calling this method will cause the built
Feature
to return an empty optional for the given property.Note that for a newly created
Feature.Builder
using theFeature#newBuilder()
method, all values will be empty by default. This method is less useful in that case. It is mainly useful when using theFeature#asBuilder()
method.- Parameters:
propertyPath
- the property for which to reset the value- Returns:
- this builder
- Throws:
IllegalArgumentException
- when the dataType has not been configured yet, the property is not of a known type, or if it doesn't exist in theDataType
.
