Constructor Detail

Maths

public Maths(java.util.Map<java.lang.String,java.lang.String> query)

Constructs a math config object from a URI string

Parameters:

query - String-String map containing the fields from the URI string

Maths

public Maths(Maths.Operation op,
             java.lang.Number rhs,
             java.lang.Boolean signed)

Constructs a config object with user explicitly requesting a signed or unsigned operation

Parameters:

op - Math operation to carry out on the input

rhs - Value on the right hand side fo the operation

signed - True to used signed operation, false for unsigned

Maths

public Maths(Maths.Operation op,
             DataSignal.DataToken rhs,
             java.lang.Boolean signed)

Constructs a config object with user explicitly requesting a signed or unsigned operation. This constructor is for updating a comparison filter in a feedback or feedforward loop

Parameters:

op - Math operation to carry out on the input

rhs - Token representing the sensor data to be used for the right hand side of the operation

signed - True to used signed operation, false for unsigned

Maths

public Maths(Maths.Operation op,
             java.lang.Number rhs)

Constructs a config object with inferred signed or unsigned operation

Parameters:

op - Math operation to carry out on the input

rhs - Value on the right hand side fo the operation

Maths

public Maths(Maths.Operation op,
             DataSignal.DataToken rhs)

Constructs a config object with inferred signed or unsigned operation. This constructor is for updating a comparison filter in a feedback or feedforward loop

Parameters:

op - Math operation to carry out on the input

rhs - Token representing the sensor data to be used for the right hand side of the operation
