Method Details

getAttributeNames

public String[] getAttributeNames()

Description copied from class: AbstractBuildable

Lists all the buildFile (XML) attribute names for this component. If this component is ALSO an AbstractConfigurable, then this list of attributes determines the appropriate attribute order for AbstractConfigurable.getAttributeDescriptions() and AbstractConfigurable.getAttributeTypes().

Specified by:

getAttributeNames in interface AutoConfigurable

Specified by:

getAttributeNames in class AbstractBuildable

Returns:

a list of all buildFile (XML) attribute names for this component

getAttributeDescriptions

public String[] getAttributeDescriptions()

Description copied from interface: AutoConfigurable

Return an array of Strings describing the attributes of this object. These strings are used as prompts in the Properties window for this object.

Specified by:

getAttributeDescriptions in interface AutoConfigurable

Specified by:

getAttributeDescriptions in class AbstractConfigurable

Returns:

an array of Strings describing the buildFile (XML) attributes of this component. These strings are used as prompts in the Properties window for this object, when the component is configured in the Editor. The order of descriptions should be the same as the order of names in AbstractBuildable.getAttributeNames()

getAttributeTypes

public Class<?>[] getAttributeTypes()

Description copied from interface: AutoConfigurable

Returns:

the Class for the buildFile (XML) attributes of this component. Valid classes include: String, Integer, Double, Boolean, Image, Color, and KeyStroke, along with any class for which a Configurer exists in VASSAL.configure. The class determines, among other things, which type of AutoConfigurer will be used to configure the attribute when the object is configured in the Editor. The order of classes should be the same as the order of names in AbstractBuildable.getAttributeNames()
