Field Details

externalPath

protected final org.eclipse.core.runtime.IPath externalPath

The path to the external folder (an OS path)

Constructor Details

ExternalPackageFragmentRoot

protected ExternalPackageFragmentRoot(org.eclipse.core.runtime.IPath externalPath,
 JavaProject project)

Constructs a package fragment root which is the root of the Java package directory hierarchy based on an external folder that is not contained in a IJavaProject and does not have an associated IResource.

ExternalPackageFragmentRoot

protected ExternalPackageFragmentRoot(org.eclipse.core.resources.IResource linkedFolder,
 org.eclipse.core.runtime.IPath externalPath,
 JavaProject project)

Method Details

determineKind

protected int determineKind(org.eclipse.core.resources.IResource underlyingResource)

An external class folder is always K_BINARY.

Overrides:

determineKind in class PackageFragmentRoot

equals

public boolean equals(Object o)

Returns true if this handle represents the same external folder as the given handle.

Overrides:

equals in class PackageFragmentRoot

See Also:

• Object.equals(java.lang.Object)

calculateHashCode

protected int calculateHashCode()

Overrides:

calculateHashCode in class PackageFragmentRoot

getElementName

public String getElementName()

Description copied from interface: IJavaElement

Returns the name of this element. This is a handle-only method.

Specified by:

getElementName in interface IJavaElement

Overrides:

getElementName in class PackageFragmentRoot

Returns:

the element name

See Also:

• IAdaptable

getKind

public int getKind()

Description copied from interface: IPackageFragmentRoot

Returns this package fragment root's kind encoded as an integer. A package fragment root can contain source files (i.e. files with one of the Java-like extensions, or .class files, but not both. If the underlying folder or archive contains other kinds of files, they are ignored. In particular, .class files are ignored under a source package fragment root, and source files are ignored under a binary package fragment root.

Specified by:

getKind in interface IPackageFragmentRoot

Overrides:

getKind in class PackageFragmentRoot

Returns:

this package fragment root's kind encoded as an integer

See Also:

• IPackageFragmentRoot

getPath

public org.eclipse.core.runtime.IPath getPath()

Description copied from interface: IJavaElement

Returns the path to the innermost resource enclosing this element. If this element is not included in an external library, the path returned is the full, absolute path to the underlying resource, relative to the workbench. If this element is included in an external library, the path returned is the absolute path to the archive or to the folder in the file system. This is a handle-only method.

Specified by:

getPath in interface IJavaElement

Overrides:

getPath in class PackageFragmentRoot

Returns:

the path to the innermost resource enclosing this element

See Also:

• IPackageFragmentRoot

getUnderlyingResource

public org.eclipse.core.resources.IResource getUnderlyingResource()
                                                           throws JavaModelException

Description copied from interface: IJavaElement

Returns the smallest underlying resource that contains this element, or null if this element is not contained in a resource.

Specified by:

getUnderlyingResource in interface IJavaElement

Overrides:

getUnderlyingResource in class PackageFragmentRoot

Returns:

the underlying resource, or null if none

Throws:

JavaModelException - if this element does not exist or if an exception occurs while accessing its underlying resource

See Also:

• IJavaElement

isExternal

public boolean isExternal()

Description copied from interface: IPackageFragmentRoot

Returns whether this package fragment root is external to the workbench (that is, a local file), and has no underlying resource.

This is a handle-only method.

Specified by:

isExternal in interface IPackageFragmentRoot

Overrides:

isExternal in class PackageFragmentRoot

Returns:

true if this package fragment root is external to the workbench (that is, a local file), and has no underlying resource, false otherwise

See Also:

• IPackageFragmentRoot

resource

public org.eclipse.core.resources.IResource resource(PackageFragmentRoot root)

Overrides:

resource in class PackageFragmentRoot

resourceExists

protected boolean resourceExists(org.eclipse.core.resources.IResource underlyingResource)

Description copied from class: Openable

Returns whether the corresponding resource or associated file exists

Overrides:

resourceExists in class Openable

toStringAncestors

protected void toStringAncestors(StringBuilder buffer)

Description copied from class: JavaElement

Debugging purposes

Overrides:

toStringAncestors in class JavaElement
