Interface IRuntimeClasspathEntry

All Known Subinterfaces:

IRuntimeClasspathEntry2

public interface IRuntimeClasspathEntry

Represents an entry on a runtime classpath. A runtime classpath entry may refer to one of the following:

• A Java project (type PROJECT) - a project entry refers to all of the built classes in a project, and resolves to the output location(s) of the associated Java project.
• An archive (type ARCHIVE) - an archive refers to a jar, zip, or folder in the workspace or in the local file system containing class files. An archive may have attached source.
• A variable (type VARIABLE) - a variable refers to a classpath variable, which may refer to a jar.
• A library (type CONTAINER) - a container refers to classpath container variable which refers to a collection of archives derived dynamically, on a per project basis.
• A contributed classpath entry (type OTHER) - a contributed classpath entry is an extension contributed by a plug-in. The resolution of a contributed classpath entry is client defined. See IRuntimeClasspathEntry2.

Clients may implement this interface for contributed a classpath entry types (i.e. type OTHER). Note, contributed classpath entries are new in 3.0, and are only intended to be contributed by the Java debugger.

Since:

2.0

Method Detail

getType

public int getType()

Returns this classpath entry's type. The type of a runtime classpath entry is identified by one of the following constants:

• PROJECT
• ARCHIVE
• VARIABLE
• CONTAINER
• OTHER

Since 3.0, a type of OTHER may be returned.

Returns:

this classpath entry's type

getMemento

public String getMemento()
                  throws CoreException

Returns a memento for this classpath entry.

Since 3.0, the memento for a contributed classpath entry (i.e. of type OTHER), must be in the form of an XML document, with the following element structure:

The id attribute is the unique identifier of the extension that contributed this runtime classpath entry type, via the extension point org.eclipse.jdt.launching.runtimeClasspathEntries. The memento element will be used to initialize a restored runtime classpath entry, via the method IRuntimeClasspathEntry2.initializeFrom(Element memento). The attributes of the memento element are client defined.

Returns:

a memento for this classpath entry

Throws:

CoreException - if an exception occurs generating a memento

getPath

public IPath getPath()

Returns the path associated with this entry, or null if none. The format of the path returned depends on this entry's type:

• PROJECT - a workspace relative path to the associated project.
• ARCHIVE - the absolute path of the assoicated archive, which may or may not be in the workspace.
• VARIABLE - the path corresponding to the associated classpath variable entry.
• CONTAINER - the path corresponding to the associated classpath container variable entry.
• OTHER - the path returned is client defined.

Since 3.0, this method may return null.

Returns:

the path associated with this entry, or null

See Also:

IClasspathEntry.getPath()

getResource

public IResource getResource()

Returns the resource associated with this entry, or null if none. A project, archive, or folder entry may be associated with a resource.

Returns:

the resource associated with this entry, or null

getSourceAttachmentPath

public IPath getSourceAttachmentPath()

Returns the path to the source archive associated with this entry, or null if this classpath entry has no source attachment.

Only archive and variable entries may have source attachments. For archive entries, the path (if present) locates a source archive. For variable entries, the path (if present) has an analogous form and meaning as the variable path, namely the first segment is the name of a classpath variable.

Returns:

the path to the source archive, or null if none

setSourceAttachmentPath

public void setSourceAttachmentPath(IPath path)

Sets the path to the source archive associated with this entry, or null if this classpath entry has no source attachment.

Only archive and variable entries may have source attachments. For archive entries, the path refers to a source archive. For variable entries, the path has an analogous form and meaning as the variable path, namely the first segment is the name of a classpath variable.

Note that an empty path (Path.EMPTY) is considered null.

Parameters:

path - the path to the source archive, or null if none

getSourceAttachmentRootPath

public IPath getSourceAttachmentRootPath()

Returns the path within the source archive where package fragments are located. An empty path indicates that packages are located at the root of the source archive. Returns a non-null value if and only if getSourceAttachmentPath returns a non-null value.

Returns:

root path within the source archive, or null if not applicable

setSourceAttachmentRootPath

public void setSourceAttachmentRootPath(IPath path)

Sets the path within the source archive where package fragments are located. A root path indicates that packages are located at the root of the source archive. Only valid if a source attachment path is also specified.

Note that an empty path (Path.EMPTY) is considered null.

Parameters:

path - root path within the source archive, or null

getClasspathProperty

public int getClasspathProperty()

Returns a constant indicating where this entry should appear on the runtime classpath by default. The value returned is one of the following:

• STANDARD_CLASSES - a standard entry does not need to appear on the runtime classpath
• BOOTSTRAP_CLASSES - a bootstrap entry should appear on the boot path
• USER_CLASSES - a user entry should appear on the path containing user or application classes

Returns:

where this entry should appear on the runtime classpath

setClasspathProperty

public void setClasspathProperty(int location)

Sets whether this entry should appear on the bootstrap classpath, the user classpath, or whether this entry is a standard bootstrap entry that does not need to appear on the classpath. The location is one of:

• STANDARD_CLASSES - a standard entry does not need to appear on the runtime classpath
• BOOTSTRAP_CLASSES - a bootstrap entry should appear on the boot path
• USER_CLASSES - a user entry should appear on the path conatining user or application classes

Parameters:

location - a classpat property constant

getLocation

public String getLocation()

Returns an absolute path in the local file system for this entry, or null if none, or if this entry is of type CONTAINER.

Returns:

an absolute path in the local file system for this entry, or null if none

getSourceAttachmentLocation

public String getSourceAttachmentLocation()

Returns an absolute path in the local file system for the source attachment associated with this entry entry, or null if none.

an absolute path in the local file system for the source attachment associated with this entry entry, or null if none

getSourceAttachmentRootLocation

public String getSourceAttachmentRootLocation()

Returns a path relative to this entry's source attachment path for the root location containing source, or null if none.

Returns:

a path relative to this entry's source attachment path for the root location containing source, or null if none

getVariableName

public String getVariableName()

Returns the first segment of the path associated with this entry, or null if this entry is not of type VARIABLE or CONTAINER.

Returns:

the first segment of the path associated with this entry, or null if this entry is not of type VARIABLE or CONTAINER

public IClasspathEntry getClasspathEntry()

Returns a classpath entry equivalent to this runtime classpath entry, or null if none.

Since 3.0, this method may return null.

Returns:

a classpath entry equivalent to this runtime classpath entry, or null

Since:

2.1

getJavaProject

public IJavaProject getJavaProject()

Returns the Java project associated with this runtime classpath entry or null if none. Runtime classpath entries of type CONTAINER may be associated with a project for the purposes of resolving the entries in a container.

Returns:
