Method Summary

Modifier and Type	Method and Description

Data	derivative(MathType[] derivType_s, int error_mode) return the tuple of derivatives of this Function with respect to all RealType components of its domain RealTuple; set result MathTypes of tuple components to derivType_s; propogate errors according to error_mode
Data	derivative(RealTuple location, RealType[] d_partial_s, MathType[] derivType_s, int error_mode) return the tuple of derivatives of this Function with respect to the RealTypes in d_partial_s; the RealTypes in d_partial_s may occur in this Function's domain RealTupleType, or, if the domain has a CoordinateSystem, in its Reference RealTupleType; set result MathTypes of tuple components to derivType_s; propogate errors according to error_mode
Function	derivative(RealType d_partial, int error_mode) return the derivative of this Function with respect to d_partial; d_partial may occur in this Function's domain RealTupleType, or, if the domain has a CoordinateSystem, in its Reference RealTupleType; propogate errors according to error_mode
Function	derivative(RealType d_partial, MathType derivType, int error_mode) return the derivative of this Function with respect to d_partial; set result MathType to derivType; d_partial may occur in this Function's domain RealTupleType, or, if the domain has a CoordinateSystem, in its Reference RealTupleType; propogate errors according to error_mode
Data	evaluate(Real domain) Evaluate this Function at domain; for 1-D domains use default modes for resampling (Data.WEIGHTED_AVERAGE) and errors (Data.NO_ERRORS)
Data	evaluate(Real domain, int sampling_mode, int error_mode) Evaluate this Function, for 1-D domains, with non-default modes for resampling and errors
Data	evaluate(RealTuple domain) Evaluate this Function at domain; use default modes for resampling (Data.WEIGHTED_AVERAGE) and errors (Data.NO_ERRORS)

Unit[]	getDomainUnits() Get the default Units of the Real components of the domain.
Field	resample(Set set) Return a Field of Function values at the samples in set using default sampling_mode (WEIGHTED_AVERAGE) and error_mode (NO_ERRORS); This combines unit conversions, coordinate transforms, resampling and interpolation
Field	resample(Set set, int sampling_mode, int error_mode) can decide whether to return the local FieldImpl returned by ((FunctionImpl) AdaptedData).resample, or whether to return a RemoteFunctionImpl adapted for that FieldImpl; the same is true for the methods: extract, binary, unary, evaluate and getSample (as long as their return value is an instanceof Field)
