Method Details

getWindowHelicity

public int getWindowHelicity(Object bank,
 byte delayWindows)

Window delay correction, for any pattern type.

Parameters:

bank - instance of HEL::decoder from the event of interest

delayWindows - number of delay windows

Returns:

delay-corrected helicity for the event of interest

checkPatterns

public boolean checkPatterns(Object bank)

Parameters:

bank - the HEL::decoder bank to check

Returns:

whether its pattern sequence looks good

checkHelicities

public boolean checkHelicities(Object bank)

Parameters:

bank - the HEL::decoder bank to check

Returns:

whether its helicity sequence looks good

check

public boolean check(Object bank)

Run all available integrity checking on a HEL::decoder bank

Parameters:

bank - the HEL::decoder bank to check

Returns:

whether everything looks good

toString

public static String toString(org.jlab.jnp.hipo4.data.Bank b)

Get a string representation of a HEL::decoder bank for human consumption.

Parameters:

b - the HEL::decoder bank to stringify

Returns:
