Method Detail

getInstance

public static TechnologyRegistry getInstance()

Returns an instance of the technology registry.

registerTechnology

public void registerTechnology(java.lang.String key,
                               java.lang.String name,
                               java.lang.String description)

Registers a top-level technology with the technology registry.

Parameters:

key - a well-defined string that identifies the technology programmatically; the key is used to bind items in the gallery to a technology.

name - a translatable string that identifies the technology in the user interface.

description - a translatable string that describes the purpose of the technology in the user interface.

registerTechnology

public void registerTechnology(java.lang.String key,
                               java.lang.String name,
                               java.lang.String description,
                               TechId parent)

Registers a child technology with the technology registry.

Parameters:

key - a well-defined string that identifies the technology programmatically; the key is used to bind items in the gallery to a technology.

name - a translatable string that identifies the technology in the user interface.

description - a translatable string that describes the purpose of the technology in the user interface.

parent - the parent technology.

registerTechnology

public void registerTechnology(java.lang.String key,
                               java.lang.String name,
                               java.lang.String description,
                               TechId[] dependencies)

Registers a dependent technology with the technology registry.

Parameters:

key - a well-defined string that identifies the technology programmatically; the key is used to bind items in the gallery to a technology.

name - a translatable string that identifies the technology in the user interface.

description - a translatable string that describes the purpose of the technology in the user interface.

dependencies - the technologies upon which the registered technology depends.

registerPseudoTechnology

public void registerPseudoTechnology(java.lang.String key,
                                     PseudoTechnologyCallback callback)

Registers a pseudo-technology with the technology registry. Pseudo-technologies are not visible in the user interface.

Parameters:

key - a well-defined string that identifies the technology programmatically; the key is used to bind items in the gallery to a technology.

callback - the callback object used to determine the visibility of gallery items tagged with the specified technology key.

Parameters:

key - a string that identifies a technology.

getTechId

public TechId getTechId(java.lang.String key)

Looks up a registered technology given the technology key.

Parameters:

key - a string that identifies a technology.

Returns:

the TechId for the specified technology, or null if no technology is registered with the specified identifier.

getAllTechIds

public TechId[] getAllTechIds()

Returns all registered technologies.

Returns:

an array of TechId instances comprising all registered technologies.

getVisibleTechIds

public TechId[] getVisibleTechIds()

Returns all visible registered technologies.

Returns:

an array of TechId instances comprising those registered technologies that are visible.

getDependenciesFor

public TechId[] getDependenciesFor(TechId techId)

Returns all of the registered technologies upon which the specified technology depends, either directly or indirectly.

Returns:

an array containing all the technologies upon which the specified technology depends.

getDependentsFor

public TechId[] getDependentsFor(TechId techId)

Returns all of the registered technologies that depend, either directly or indirectly, on the specified technology.

Returns:

an array containing all the technologies that depend on the specified technology.
