public boolean isBlocked()

Description copied from interface: IDecorable

Is this element blocked (or does it contain blocked elements).

Specified by:

isBlocked in interface IDecorable

Returns:

true If this element is blocked, false if this element isn't or cannot be blocked.

isBlockedDiffVersion

public boolean isBlockedDiffVersion()

Description copied from interface: IDecorable

Is this element blocked (or does it contain blocked elements), that have a different version.

Specified by:

isBlockedDiffVersion in interface IDecorable

Returns:

true If this element is blocked, false if this element isn't or cannot be blocked.

isIgnored

public boolean isIgnored()

Description copied from interface: IDecorable

Is this element is ignored.

Specified by:

isIgnored in interface IDecorable

Returns:

true If this element is ignored, false if this element isn't or cannot be ignored.

hasUnresolved

public boolean hasUnresolved()

Description copied from interface: IDecorable

Does this element have unresolved references.

Specified by:

hasUnresolved in interface IDecorable

Returns:

true If this element has unresolved, false if this element isn't or cannot have unresolved.

isUnreferenced

public boolean isUnreferenced()

Description copied from interface: IDecorable

Is this element referred to by anyone?

Specified by:

isUnreferenced in interface IDecorable

Returns:

true if this element has no references to it (other than possibly itself), otherwise false.

supportingDecorations

Specified by:

supportingDecorations in interface IDecorable

Returns:

true if this node is currently supporting decorations, otherwise false

hasWontLoad

public boolean hasWontLoad()

Description copied from interface: IDecorable

Will this not load or does this element contain elements that won't load. Elements typically won't load if something they depend on won't load.

Specified by:

hasWontLoad in interface IDecorable

Returns:

true if this node has elements that won't load (possibly itself), otherwise false

getIconName

public Image getIconName()

Description copied from interface: ITree

The associated Icon.

Specified by:

Returns:

The Icon for this node.

hasChildren
