isBlockedDiffVersion

public boolean isBlockedDiffVersion()

Getter method indicating whether or not this location contains blocked classes (some blocked with different versions).

Specified by:

isBlockedDiffVersion in interface IDecorable

Returns:

true If this location contains blocked classes (with different locations), otherwise false

Since:

setBlockedDiffVersion

protected void setBlockedDiffVersion(boolean blocked)

Setter method for the has blocked (with different versions) property.

Parameters:

blocked - The blocked flag.

Since:

1.0

hasUnresolved

public boolean hasUnresolved()

Getter method indicating whether or not this location contains unresolved classes.

isUnreferenced

public boolean isUnreferenced()

Description copied from interface: IDecorable

Is this element referred to by anyone?

Specified by:

isUnreferenced in interface IDecorable

Returns:

Returns:

true if this node is currently supporting decorations, otherwise false

hasWontLoad

public boolean hasWontLoad()

Specified by:

hasWontLoad in interface IDecorable

Returns:

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

getIconName
