public class FindIntersection

extends constructFamilyBeacon

implements constants

FindIntersection(EuWrapper, EuLab)

This constructor tries, given tentative information from a user, to find an input mode.

FindIntersection(EuWrapper, EuWrapper, EuArguments, int)

This constructor tries, given full information for a LEA program, to find an input and an output mode and checks that no arguments are passed.

checkSegment(int)

Throws an exception in segment is not PREMISE or SOLUTION.

findAllConstructs(EuWrapper, EuLab)

Constructs a circle and places it in the provided EuWrapper.

numberOfModes(int)

subTypeChecks(EuWrapper, int, int)

theMode(int, int)

weedWithBeacon(EuWrapper)

Weeds using pointWeeder();

 public FindIntersection(EuWrapper in,
                         EuWrapper out,
                         EuArguments args,
                         int beacon) throws LeaSyntaxException

This constructor tries, given full information for a LEA program, to find an input and an output mode and checks that no arguments are passed. Also checks that no beacons are passed.

Parameters:

in - the input @see EuWrapper

out - the output @see EuWrapper

args - arguments

beacon - a beacon, or 0 if no such was requested

 public FindIntersection(EuWrapper sel,
                         EuLab lab) throws LeaSyntaxException

This constructor tries, given tentative information from a user, to find an input mode.

Parameters:

sel - the user selections in a @see EuWrapper

lab - the current EuLab

 public String name()

Returns:

The LEA name of this command

Overrides:

name in class EuMove

 public int number()

Returns:

A number representing this move internally

Overrides:

number in class EuMove

 protected void weedWithBeacon(EuWrapper findings) throws LeaRuntimeException, LeaInternalException

Weeds using pointWeeder();

Parameters:

outputmode - an output mode or 0 if none has been determined

findings - a EuWrapper in STOP phase

Overrides:

weedWithBeacon in class constructFamily

 protected void findAllConstructs(EuWrapper results,
                                  EuLab lab) throws LeaRuntimeException

Constructs a circle and places it in the provided EuWrapper.

Parameters:

results - a EuWrapper which must be in the DRIVE_E phase.

lab - the EuLab in which to get the objects with which to construct

Throws: LeaRuntimeException

if radius is not set

Overrides:

findAllConstructs in class constructFamily

 protected int numberOfModes(int io)

Parameters:

io - either INPUT or OUTPUT (ignored)

Returns:

there are 2 input and 2 output modes

Overrides:

numberOfModes in class constructFamily

 protected int theMode(int i,
                       int io)

Parameters:

i - the number of the mode

io - either INPUT or OUTPUT

Returns:

a mask of the specified input or output mode

Overrides:

theMode in class constructFamily

 protected boolean subTypeChecks(EuWrapper sel,
                                 int i,
                                 int io)

Parameters:

sel - a EuWrapper in DRIVE_I or PARK mode

i - the number of the mode

io - either INPUT or OUTPUT

Returns:

true if subtype specifications are met, and they always are

Overrides:

subTypeChecks in class constructFamily

 protected void checkSegment(int segment) throws LeaRuntimeException

Throws an exception in segment is not PREMISE or SOLUTION.

Parameters:

segment - the current segment

Throws: LeaRuntimeException

if not PREMISE or SOLUTION

Overrides:

checkSegment in class constructFamily
