Constructor Detail

ExtendedDataTypeFloat

public ExtendedDataTypeFloat(String id)

Constructor setting the id.

Parameters:

id - id

Method Detail

setValue

public final float[] setValue(float[] storage,
                              int i,
                              T value)

Returns an updated list/array/vector of the storage type, including a new value at given index.

Specified by:

setValue in class ExtendedDataType<T extends org.djunits.value.vfloat.scalar.AbstractFloatScalar<U,T>,O extends org.djunits.value.vfloat.vector.AbstractFloatVector<U,O>,float[]>

Parameters:

storage - storage

i - index to store next value

value - value to add

Returns:

updated list/array/vector of the storage type, including a new value at given index

initializeStorage

public final float[] initializeStorage()

Returns an initial storage object.

Specified by:

initializeStorage in class ExtendedDataType<T extends org.djunits.value.vfloat.scalar.AbstractFloatScalar<U,T>,O extends org.djunits.value.vfloat.vector.AbstractFloatVector<U,O>,float[]>

Returns:

initial storage object.

formatValue

public final String formatValue(String format,
                                T value)

Formats the value into a string. If the value is numeric, the default implementation is:

 String.format(format, value.si);
 

Specified by:

formatValue in class ExtendedDataType<T extends org.djunits.value.vfloat.scalar.AbstractFloatScalar<U,T>,O extends org.djunits.value.vfloat.vector.AbstractFloatVector<U,O>,float[]>

Parameters:

format - format

value - value

Returns:

formatted value

getOutputValue

public final T getOutputValue(O output,
                              int i)
                       throws SamplingException

Returns a specific output value. This is used to store extended data types as generic file, i.e. text file.

Specified by:

getOutputValue in class ExtendedDataType<T extends org.djunits.value.vfloat.scalar.AbstractFloatScalar<U,T>,O extends org.djunits.value.vfloat.vector.AbstractFloatVector<U,O>,float[]>

Parameters:

output - output

i - index of value to return

Returns:

the i'th output value

Throws:

SamplingException - when i is out of bounds.

getStorageValue

public T getStorageValue(float[] storage,
                         int i)
                  throws SamplingException

Returns a specific storage value. This is used to bypass conversion to the output type when trajectories are cut.

Specified by:

getStorageValue in class ExtendedDataType<T extends org.djunits.value.vfloat.scalar.AbstractFloatScalar<U,T>,O extends org.djunits.value.vfloat.vector.AbstractFloatVector<U,O>,float[]>

Parameters:

storage - storage

i - index of value to return

Returns:

the i'th output value

Throws:

SamplingException - when i is out of bounds.

convertValue

protected abstract T convertValue(float value)

Convert float to typed value.

Parameters:

value - float value

Returns:

typed value

convert

public O convert(float[] storage,
                 int size)

Convert storage type to output type.

Specified by:

convert in class ExtendedDataType<T extends org.djunits.value.vfloat.scalar.AbstractFloatScalar<U,T>,O extends org.djunits.value.vfloat.vector.AbstractFloatVector<U,O>,float[]>

Parameters:

storage - stored data

size - size of trajectory

Returns:

converted output

convert

protected abstract O convert(float[] storage)
                      throws org.djunits.value.ValueException

Convert float array to typed array.

Parameters:

storage - float array storage

Returns:

typed array

Throws:

org.djunits.value.ValueException - when float array cannot be converted
