public class Parser
extends Object

Parses and executes a sequence of tree operations represented as a comma separated sequence of commands [iIdDlLP]<int> or W where:

I<int> indicates that this value should be inserted into the structure;
D<int> deletes this value from the structure;
L<int> locates this value in the structure;
R<int> rotate at node with this key;
P<int> pauses the simulation for this many milliseconds;
W pauses the simulation and resumes when the display is static (wait)
K toggles the display of keys/nodes
+ turns on the display of keys
N toggles the use of inorder display ("neat")
! turns on the use of inorder display
[ indicates that the current structure should be saved for later recall
] recall a saved structure (can be called more than once for the same saved configuration
F the first time encountered, stores the current
configuration; thereafter, restores this saved configuration.
*<int> insert this value into the tree without animating the insertion. primarily for initializing a configuration
R repeat this entire sequence of instructions, omitting the initial prefix of "*"-insertions.

By default, when in demo mode (parameter name=demoMode" with value="true") nodes with values 2 are blue, 4 purple, 6 red and 8 orange; in this mode, all others have the default color (initially set to gray).

endOp()

hasMoreOps()
Returns true if there are additional operations to be performed in the given operation sequence.
next()
Parse and retrieve the next action to be performed; the next operation is consumed
ready()

ready
public boolean ready()
endOp
public boolean endOp()
next
public Action next() throws IOException

Parse and retrieve the next action to be performed; the next operation is consumed
hasMoreOps
public boolean hasMoreOps()

Returns true if there are additional operations to be performed in the given operation sequence.
