Method Summary

ILibrarySpecification	findChildLibrarySpecification(org.apache.hivemind.Resource libraryResource, String path, org.apache.hivemind.Location location) Finds a child library specification for some parent library specification.
IComponentSpecification	getComponentSpecification(org.apache.hivemind.Resource libraryResource, String specificationPath, org.apache.hivemind.Location location) Retrieves a component specification, parsing it as necessary.
IComponentSpecification	getPageSpecification(org.apache.hivemind.Resource libraryResource, String specificationPath, org.apache.hivemind.Location location) Retrieves a page specification, parsing it as necessary.

Method Detail

findChildLibrarySpecification

ILibrarySpecification findChildLibrarySpecification(org.apache.hivemind.Resource libraryResource,
                                                    String path,
                                                    org.apache.hivemind.Location location)

Finds a child library specification for some parent library specification.

Parameters:

libraryResource - the Resource from which the parent library (or application) specification was loaded

path - the relative path from the parent specification resource to the library specification. As a special case, a path starting with a leading slash is assumed to be on the classpath.

location - TODO

Returns:

the library specification.

getPageSpecification

IComponentSpecification getPageSpecification(org.apache.hivemind.Resource libraryResource,
                                             String specificationPath,
                                             org.apache.hivemind.Location location)

Retrieves a page specification, parsing it as necessary.

Parameters:

libraryResource - the base resource for resolving the path to the page specification; this will be the resource for the library (or application) specification

specificationPath - the path to the specification to be parsed

location - used to report errors

Throws:

org.apache.hivemind.ApplicationRuntimeException - if the specification doesn't exist, is unreadable or invalid.

getComponentSpecification

IComponentSpecification getComponentSpecification(org.apache.hivemind.Resource libraryResource,
                                                  String specificationPath,
                                                  org.apache.hivemind.Location location)

Retrieves a component specification, parsing it as necessary.

Parameters:

libraryResource - the base resource for resolving the path to the page specification; this will be the resource for the library (or application) specification

specificationPath - the path to the specification to be parsed

location - used to report errors

Throws:

org.apache.hivemind.ApplicationRuntimeException - if the specification doesn't exist, is unreadable or invalid.
