Field Summary

static int	DEFAULT_OPTIONS Default expansion/contraction options.
static int	FAST_COORDS Fast coordinate calculation in expand.
static int	MDL_EXPAND MDL like multiple group expansion flag.
static int	NONRECURSIVE_EXPAND Recursive expansion of child groups.
static int	REVERSIBLE_EXPAND Reversible expansion or contraction.

Method Detail

contract

boolean contract(int opts)

Contracts the S-group.

Parameters:

opts - contraction options (currently neglected)

Returns:

true if the operation was successful, false if the group cannot be contracted

See Also:

DEFAULT_OPTIONS, REVERSIBLE_EXPAND

expand

boolean expand(int opts)

Expands the S-group.

Parameters:

opts - expansion options

Returns:

true if the operation was successful, false if the group cannot be expanded

See Also:

DEFAULT_OPTIONS, MDL_EXPAND, REVERSIBLE_EXPAND

isExpanded

boolean isExpanded()

Is this S-group expanded?

Returns:

true if expanded, false if not
