Annotation Type DoubleProperty

@Target(value=FIELD)
 @Retention(value=RUNTIME)
public @interface DoubleProperty

Indicates that a field in an PipelineComponentConfiguration is a double configuration property. Use this annotation with PipelineComponentConfiguration member variables of type primitive double or java.lang.Double.

The CAS Server automatically validates all configuration property constraints such as isRequired, possibleValues, minValue, and maxValue.

Here is an example usage of the @DoubleProperty annotation with all parameters:

 @DoubleProperty(name="myDouble" displayName="My Double",
        description="My Double description", defaultValue="1.1",
        isRequired=true, isAlwaysVisible=true, configGroup="Basic Options",
        minValue=1.1, maxValue=3.3,
        possibleValues={
                @EnumValue(value="1.1", label="1.1 label"),
                @EnumValue(value="2.2", label="2.2 label"),
                @EnumValue(value="3.3", label="3.3 label")}
 )
 private Double myDoubleField;

Element Detail

name

public abstract String name

The name of the configuration property. This will be used in crawl configurations sent through the CAS Server Web API and crawl configuration files used by cas-cmd. If not specified, name will default to the member variable's name.

Default:

""

isRequired

public abstract boolean isRequired

Indicates whether or not the property is required. Crawl configurations must contain valid values for all required properties.

""

defaultValue

public abstract String defaultValue

The default value for the property. This value displays in CAS Console as the default value for both required and non-required configuration properties. The CAS Server also uses this value for any unspecified non-required configuration properties. The value must in the format specified by Double.valueOf(String). An empty string indicates the property has no default value.

Default:

""

isAlwaysVisible

public abstract boolean isAlwaysVisible

Indicates whether or not to always show the configuration property in the CAS Console even if the configuration property is not required.

-1.7976931348623157E308

configGroup

public abstract String configGroup

The name of the ConfigurationGroup this configuration property belongs to. This must correspond to a ConfigGroup annotation on the PipelineComponentConfiguration. Alternatively the ConfigGroup can be specified using the ConfigurationGroup.propertyOrder() annotation parameter.
