Method Detail

getControlledPackageMapping

public java.util.Map<java.lang.String,ControlledPackageType> getControlledPackageMapping()

Description copied from interface: ComponentClassResolver

Used to identify which packages are controlled packages (from which components are loaded). Future expansion may allow for additional packages which are live reloaded but not components (or perhaps are transformed, but not as components).

Specified by:

getControlledPackageMapping in interface ComponentClassResolver

Returns:

a mapping from package name to ControlledPackageType.

objectWasInvalidated

public void objectWasInvalidated()

When the class loader is invalidated, clear any cached page names or component types.

Specified by:

objectWasInvalidated in interface InvalidationListener

resolvePageNameToClassName

public java.lang.String resolvePageNameToClassName(java.lang.String pageName)

Description copied from interface: ComponentClassResolver

Converts a logical page name (such as might be encoded into a URL) into a fully qualified class name. The case of the page name is irrelevant.

Specified by:

resolvePageNameToClassName in interface ComponentClassResolver

Parameters:

pageName - page name

Returns:

fully qualified class name for the page

isPageName

public boolean isPageName(java.lang.String pageName)

Description copied from interface: ComponentClassResolver

For a particular path, determines if the path is a logical page name. The check is case insensitive.

Specified by:

isPageName in interface ComponentClassResolver

Parameters:

pageName - potential logical page name

Returns:

true if the page name is valid

isPage

public boolean isPage(java.lang.String pageClassName)

Description copied from interface: ComponentClassResolver

Returns true if the class name is specifically a page class, and not a component, mixin or base class.

Specified by:

isPage in interface ComponentClassResolver

Returns:

true if a page class

getPageNames

public java.util.List<java.lang.String> getPageNames()

Description copied from interface: ComponentClassResolver

Returns a list of all page names, in sorted order. These are the "canonical" page names.

Specified by:

getPageNames in interface ComponentClassResolver

getComponentNames

public java.util.List<java.lang.String> getComponentNames()

Description copied from interface: ComponentClassResolver

Returns a list of all component names, in sorted order. These are the "canonical" component names.

Specified by:

getComponentNames in interface ComponentClassResolver

getMixinNames

public java.util.List<java.lang.String> getMixinNames()

Description copied from interface: ComponentClassResolver

Returns a list of all mixin names, in sorted order. These are the "canonical" mixin names.

Specified by:

getMixinNames in interface ComponentClassResolver

resolveComponentTypeToClassName

public java.lang.String resolveComponentTypeToClassName(java.lang.String componentType)

Description copied from interface: ComponentClassResolver

Converts a component type (a logical component name such as might be used inside a template or annotation) into a fully qualified class name. Case is ignored in resolving the name.

Specified by:

resolveComponentTypeToClassName in interface ComponentClassResolver

Parameters:

componentType - a logical component type

Returns:

fully qualified class name

resolveMixinTypeToClassName

public java.lang.String resolveMixinTypeToClassName(java.lang.String mixinType)

Description copied from interface: ComponentClassResolver

Converts a logical mixin type (as with component types) into a fully qualified class name. Case is ignored when resolving the name.

Specified by:

resolveMixinTypeToClassName in interface ComponentClassResolver

Parameters:

mixinType - a logical mixin type

Returns:

fully qualified class name

resolvePageClassNameToPageName

public java.lang.String resolvePageClassNameToPageName(java.lang.String pageClassName)

Description copied from interface: ComponentClassResolver

Converts a fully qualified page class name into a page name (often, for inclusion as part of the URI). This value may later be passed to ComponentClassResolver.resolvePageNameToClassName(String).

Specified by:

resolvePageClassNameToPageName in interface ComponentClassResolver

Parameters:

pageClassName - fully qualified name of a page class

Returns:

equivalent logical page name

canonicalizePageName

public java.lang.String canonicalizePageName(java.lang.String pageName)

Description copied from interface: ComponentClassResolver

Returns the canonical form of a page name. The canonical form uses character case matching the underlying class name.

Specified by:

canonicalizePageName in interface ComponentClassResolver

getFolderToPackageMapping

public java.util.Map<java.lang.String,java.lang.String> getFolderToPackageMapping()

Description copied from interface: ComponentClassResolver

A mapping from virtual folder name to a package name (used for converting classpath Assets to client URLs). This is derived from the contributed LibraryMappings. It is allowed to contribute multiple root packages as a single folder name. In this case, the best common package name is used. For example, if both com.example.main and com.example.extras is mapped to folder "example", then the package mapping for "example" will be com.example.

Specified by:

getFolderToPackageMapping in interface ComponentClassResolver

ClasspathAssetAliasManager

getLibraryNames

Specified by:

getLibraryNames in interface ComponentClassResolver

Returns:

sorted names of libraries

getLibraryNameForClass

public java.lang.String getLibraryNameForClass(java.lang.String className)

Description copied from interface: ComponentClassResolver

Specified by:

getLibraryNameForClass in interface ComponentClassResolver

Returns:

library name

getLibraryMappings

public java.util.Collection<LibraryMapping> getLibraryMappings()

Description copied from interface: ComponentClassResolver
