Detailed Description

class Dt1DTableFn:

Dt1DTableFn holds a 1D table function. The data is represented in arbitrary increments. Methods are provided for looking up linearly interpolated values and integrating over a specified range. The time for a table lookup grows like log(n), where n is the number of data points.

init for 0-D table

virtual bool Dt1DTableFn::init	(	const DtU32	n,
		const DtReal *	domain,
		const DtReal *	data
	)		[virtual]

init for regular 1-D table with DtReal pointer n is the number of data points, domain and data are the corresponding domain and range values for the data points.

		const DtNLengthRealVector &	domain,
		const DtNLengthRealVector &	data
	)		[virtual]

init for regular 1-D table with vector data.

virtual const char* Dt1DTableFn::readerWriterType

(

)

const [virtual]

Used to supply a string type that this reader writer type is.

This can be used in place of dynamic-casting. Also used by the opd editor to determine which type of control to create

Reimplemented from DtBaseTableFunction.

virtual DtReal Dt1DTableFn::lookup	(	DtReal	coordinate1,
			...
	)		const [virtual]

Look up data.

Implements DtBaseTableFunction.

virtual DtReal Dt1DTableFn::lookup

(

const DtReal *

coordinates

)

const [virtual]

Implements DtBaseTableFunction.

virtual DtReal Dt1DTableFn::integrate	(	DtReal	lower,
		DtReal	upper,
			...
	)		const [virtual]

Integrate the function from the lower to the upper bound.

Implements DtBaseTableFunction.

virtual void Dt1DTableFn::getSelf	(	DtlObjPtr	args,
		const DtFilename &	searchPath,
		const DtVariableBindingsList &	variableBindings
	)		[virtual]

getSelf just calls the parent then calls the appropriate init().

virtual void Dt1DTableFn::putData	(	FILE *	fp,
		int	indentLevel = 0
	)		[virtual]

Write/get data.

Implements DtBaseTableFunction.

virtual DtlObjPtr Dt1DTableFn::getData	(	DtlObjPtr	args,
		const DtFilename &	searchPath,
		const DtVariableBindingsList &	variableBindings
	)		[virtual]

Implements DtBaseTableFunction.

DtU32 Dt1DTableFn::findIndex

(

DtReal

num

)

const [protected]

Find an index for a real value greater than the lowest domain value.

Uses a binary search to find it. The index is the point with the largest domain that is less than the value.
