Annotation Type StringProperty

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

Indicates that a field in an PipelineComponentConfiguration is a string configuration property. Use this annotation with PipelineComponentConfiguration member variables of type java.lang.String, arrays of java.lang.String, or a Collection of type java.lang.String.

For multiple value Strings, this annotation can be used with String arrays, Collections, Lists, Sets, or any concrete Collection implementation with a public, zero argument constructor.

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

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

 @StringProperty(name="myString" displayName="My String",
        description="My String description", defaultValue="value1",
        isRequired=true, isAlwaysVisible=true, configGroup="Basic Options",
        maxLength=6, isMultiLine=false,
        possibleValues={
                @EnumValue(value="value1", label="label1"),
                @EnumValue(value="value2", label="label2"),
                @EnumValue(value="value3", label="label3")}
 )
 private String myStringField;

EnumValue[]	possibleValues Specifies the set of possible values for this configuration property.

name

public abstract String name

The name of the configuration property. This will be used in crawl configurations sent through the CAS Server API and crawl configuration files used by cas-cmd. If not specified, name defaults 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.

Default:

false

possibleValues

public abstract EnumValue[] possibleValues

Specifies the set of possible values for this configuration property. An empty set indicates that valid values aren't enumerated.

Default:

{}

description

public abstract String description

A description of the configuration property.

Default:

""

displayName

public abstract String displayName

The display name of the configuration property shown in CAS Console. If not specified, displayName defaults to the configuration property's name.

Default:

""

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. An empty string indicates the property has no default value.

Default:

""

isPassword

public abstract boolean isPassword

Specifies whether or the configuration property is a password. Password properties are masked in CAS Console and are not returned by the CAS Server when fetching crawl configurations.

Default:

false

isAlwaysVisible

public abstract boolean isAlwaysVisible

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

Default:

false

maxLength

public abstract int maxLength

Specifies the maximum length of the configuration property value. This must be a positive integer.

Default:

255

isMultiLine

public abstract boolean isMultiLine

Specifies that the configuration property is a multi-line String. If true, CAS Console renders the property with a multi-line text editor rather than a single-line text editor.

Default:

false

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.
