Constructor Details

Zoomer

public Zoomer()

Method Details

init

protected void init()

getConfigureTypeName

public static String getConfigureTypeName()

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

Return the Class for the attributes of this object. Valid classes are: String, Integer, Double, Boolean, Image, File, Color, and KeyStroke

Specified by:

getAttributeTypes in interface AutoConfigurable

Specified by:

getAttributeTypes in class AbstractConfigurable

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()

addTo

public void addTo(Buildable b)

Description copied from interface: Buildable

Adds this component to its parent. In order to make Buildable objects extensible, the child is responsible for adding itself to the parent. That way, Buildable subcomponents can be defined in an extension package without needing to modify the containing class.

Specified by:

addTo in interface Buildable

Parameters:

b - parent Buildable to add this component to as a subcomponent.

getAttributeValueString

public String getAttributeValueString(String key)

Description copied from interface: AutoConfigurable

Called by the Buildable.getBuildElement(org.w3c.dom.Document) method to write the attributes into an XML element

Specified by:

getAttributeValueString in interface AutoConfigurable

Specified by:

getAttributeValueString in interface Translatable

Specified by:

getAttributeValueString in class AbstractBuildable

Parameters:

key - the name of the attribute. Will be one of those listed in AbstractBuildable.getAttributeNames()

Returns:

a String representation of the XML buildFile attribute with the given name. When initializing a module, this String value will loaded from the XML and passed to AbstractBuildable.setAttribute(java.lang.String, java.lang.Object). It is also frequently used for checking the current value of an attribute.

setAttribute

public void setAttribute(String key,
 Object val)

Description copied from class: AbstractBuildable

Sets a buildFile (XML) attribute value for this component. The key parameter will be one of those listed in AbstractBuildable.getAttributeNames(). If the value parameter is a String, it will be the value returned by AbstractBuildable.getAttributeValueString(java.lang.String) for the same key. If the implementing class extends AbstractConfigurable, then value will be an instance of the corresponding Class listed in AbstractConfigurable.getAttributeTypes()

Specified by:

setAttribute in interface AutoConfigurable

Specified by:

setAttribute in interface Translatable

Specified by:

setAttribute in class AbstractBuildable

Parameters:

key - the name of the attribute. Will be one of those listed in AbstractBuildable.getAttributeNames()

val - If the value parameter is a String, it will be the value returned by AbstractBuildable.getAttributeValueString(java.lang.String) for the same key. If the implementing class extends AbstractConfigurable, then value can also be an instance of the corresponding Class listed in AbstractConfigurable.getAttributeTypes()

getAllowableConfigureComponents

public Class<?>[] getAllowableConfigureComponents()

Specified by:

getAllowableConfigureComponents in interface Configurable

Returns:

a list of valid sub-component Classes. If a Class appears in this list, then instances of that class may be added to this component from the Editor's ConfigureTree window by right-clicking on the component and selecting the appropriate "Add" option.

removeFrom

public void removeFrom(Buildable b)

Description copied from interface: Configurable

Remove this component from its parent

Specified by:

removeFrom in interface Configurable
