Method Detail

getAbsoluteClassPathElements

List getAbsoluteClassPathElements()

Get a list of elements that comprise the class path for this component. Each element represents either a directory (containing class files) or a jar/zip file. The elements are absolute paths and are returned with a forward slash as their file separators.

Returns:

a list of String objects containing class path elements.

getDescription

String getDescription()

Return the description of the component.

Returns:

the description of the component from the installation descriptor.

getWorkspaceRoot

String getWorkspaceRoot()

Return the workspace root directory for the component.

Returns:

the workspace root directory path.

isBinding

boolean isBinding()

Return an indication as to whether the component being installed is a Binding Component.

Returns:

true if the component is a BC, false if not.

isBootstrapClassLoaderSelfFirst

boolean isBootstrapClassLoaderSelfFirst()

Return an indication as to whether the bootstrap class loader should use the normal hierarchy (parent-first) or an inverted hierarchy (self-first).

Returns:

true if the bootstrap class loader should use the self-first hierarchy, false if it should use parent-first.

isComponentClassLoaderSelfFirst

boolean isComponentClassLoaderSelfFirst()

Return an indication as to whether the component class loader should use the normal hierarchy (parent-first) or an inverted hierarchy (self-first).

Returns:

true if the component class loader should use the self-first hierarchy, false if it should use parent-first.

isEngine

boolean isEngine()

Return an indication as to whether the component being installed is a Service Engine.

Returns:

true if the component is a SE, false if not.

setContext

void setContext(ComponentContext context)

Set the reference to the ComponentContext for this component.

Parameters:

context - is the component context.
