Method Details

getLayer

public int getLayer()

Returns:

the layer (1...6)

setLayer

public void setLayer(int _Layer)

Sets the layer

Parameters:

_Layer -

getStrip

public int getStrip()

Returns:

the strip number (1...256)

setStrip

public void setStrip(int _Strip)

Sets the strip number

Parameters:

_Strip -

getEnergy

public double getEnergy()

the Edep in MeV

setEnergy

public void setEnergy(double _Edep)

Sets the Edep

Parameters:

_Edep -

getTime

public double getTime()

setTime

compareTo

public int compareTo(Hit arg)

Specified by:

compareTo in interface Comparable<Hit>

Parameters:

Returns:

an int used to sort a collection of hits by wire number. Sorting by wire is used in clustering.

equal

Parameters:

otherHit -

Returns:

a boolean comparing 2 hits based on basic descriptors; returns true if the hits are the same

isClose

public boolean isClose(Hit other)

Parameters:

other -

Returns:

a boolean comparing 2 hits based on basic descriptors; returns true if the hits are the same

getClusterIndex

public int getClusterIndex()

setClusterIndex

public void setClusterIndex(int _AssociatedClusterIndex)

fetchHits

public static List<Hit> fetchHits(DataEvent event,
 IndexedTable timecuts,
 IndexedTable statuses)

toString

public String toString()

Overrides:

toString in class Object

Returns:

print statement with hit information
