public abstract class AbstractBuildable
extends AbstractImageFinder
implements Buildable, ValidityChecker, PropertyNameSource

Abstract implementation of the Buildable interface. To make a Buildable component, in other words a component which can be read from the XML buildFile along with a set of attributes, extend this class -- or more likely AbstractConfigurable if the component is also to be editable/configurable in the Editor window. You'll need to implement the methods and specify the Buildable attributes of this class, and the build process is handled automatically.

AbstractBuildable

public AbstractBuildable()

Method Details

build

public void build(Element e)

Build this component by getting all XML attributes of the XML element and calling setAttribute(java.lang.String, java.lang.Object) with the String value of the attribute

Specified by:

build in interface Buildable

Parameters:

e - the XML element containing the object data

getAttributeNames

public abstract String[] getAttributeNames()

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().

Returns:

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

setAttribute

public abstract void setAttribute(String key,
 Object value)

Sets a buildFile (XML) attribute value for this component. The key parameter will be one of those listed in getAttributeNames(). If the value parameter is a String, it will be the value returned by 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()

Parameters:

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

value - If the value parameter is a String, it will be the value returned by 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()

getAttributeValueString

public abstract String getAttributeValueString(String key)

Parameters:

key - the name of the attribute. Will be one of those listed in 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 setAttribute(java.lang.String, java.lang.Object). It is also frequently used for checking the current value of an attribute.

getComponents

@Deprecated(since="2020-08-06",
            forRemoval=true)
public <T> Enumeration<T> getComponents(Class<T> target)

Deprecated, for removal: This API element is subject to removal in a future version.

Use getComponentsOf(Class) instead.

Returns:

all build components that are an instance of the given class

getComponentsOf

public <T> List<T> getComponentsOf(Class<T> target)

Returns:

all build components that are an instance of the given class

getAllDescendantComponents

@Deprecated(since="2020-08-06",
            forRemoval=true)
public <T> Enumeration<T> getAllDescendantComponents(Class<T> target)

Deprecated, for removal: This API element is subject to removal in a future version.

Use getAllDescendantComponentsOf(Class) instead.

Recursively descend the build tree and return an enumeration of all components that are instances of the given class

Parameters:

target - Target class

Returns:

Results

getAllDescendantComponentsOf

public <T> List<T> getAllDescendantComponentsOf(Class<T> target)

Recursively descend the build tree and return a List of all components that are instances of the given class

Parameters:

target - Target class

Returns:

List of all components that are instances of the given class

getBuildElement

public Element getBuildElement(Document doc)

Specified by:

getBuildElement in interface Buildable

Parameters:

doc - XML file

Returns:

an XML element from which this component can be built

add

public void add(Buildable b)

Add a Buildable object to this object

Specified by:

add in interface Buildable

Parameters:

b - Child to attach to this buildable as a subcomponent

getBuildComponents

@Deprecated(since="2020-08-06",
            forRemoval=true)
public Enumeration<Buildable> getBuildComponents()

Deprecated, for removal: This API element is subject to removal in a future version.

Use getBuildables() instead.

Returns:

an enumeration of Buildable objects which are the direct children of this object in the Buildable containment hierarchy. The getBuildElement(org.w3c.dom.Document) method uses these objects to construct the XML element from which this object can be built.

getBuildables

public List<Buildable> getBuildables()

Returns:

a Collection of Buildable objects which are the direct children of this object in the Buildable containment hierarchy. The getBuildElement(org.w3c.dom.Document) method uses these objects to construct the XML element from which this object can be built.

validate

public void validate(Buildable target,
 ValidationReport report)

Specified by:

validate in interface ValidityChecker

getPropertyNames

public List<String> getPropertyNames()

Override this method to provide a list of properties to be exposed for use by expressions in the module.

Specified by:

getPropertyNames in interface PropertyNameSource

Returns:

Default implementation of PropertyNameSource - No properties exposed

addImageNamesRecursively

public void addImageNamesRecursively(Collection<String> s)

Adds all images used by this component AND any subcomponents to the collection

Specified by:

addImageNamesRecursively in interface ImageSearchTarget

Overrides:

addImageNamesRecursively in class AbstractImageFinder

Parameters:

s - Collection to add image names to
