Member Function Documentation

static vtkStringToNumeric* vtkStringToNumeric::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkDataObjectAlgorithm.

static int vtkStringToNumeric::IsTypeOf

(

const char *

name

)

[static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataObjectAlgorithm.

virtual int vtkStringToNumeric::IsA

(

const char *

name

)

[virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataObjectAlgorithm.

static vtkStringToNumeric* vtkStringToNumeric::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkDataObjectAlgorithm.

virtual vtkObjectBase* vtkStringToNumeric::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkDataObjectAlgorithm.

vtkStringToNumeric* vtkStringToNumeric::NewInstance

(

)

const

Reimplemented from vtkDataObjectAlgorithm.

void vtkStringToNumeric::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		[virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkDataObjectAlgorithm.

virtual void vtkStringToNumeric::SetForceDouble

(

bool

)

[virtual]

Convert all numeric columns to vtkDoubleArray, even if they contain only integer values. Default is off.

virtual bool vtkStringToNumeric::GetForceDouble

(

)

[virtual]

Convert all numeric columns to vtkDoubleArray, even if they contain only integer values. Default is off.

virtual void vtkStringToNumeric::ForceDoubleOn

(

)

[virtual]

Convert all numeric columns to vtkDoubleArray, even if they contain only integer values. Default is off.

virtual void vtkStringToNumeric::ForceDoubleOff

(

)

[virtual]

Convert all numeric columns to vtkDoubleArray, even if they contain only integer values. Default is off.

virtual void vtkStringToNumeric::SetDefaultIntegerValue

(

int

)

[virtual]

Set the default integer value assigned to arrays. Default is 0.

virtual int vtkStringToNumeric::GetDefaultIntegerValue

(

)

[virtual]

Set the default integer value assigned to arrays. Default is 0.

virtual void vtkStringToNumeric::SetDefaultDoubleValue

(

double

)

[virtual]

Set the default double value assigned to arrays. Default is 0.0

virtual double vtkStringToNumeric::GetDefaultDoubleValue

(

)

[virtual]

Set the default double value assigned to arrays. Default is 0.0

virtual void vtkStringToNumeric::SetTrimWhitespacePriorToNumericConversion

(

bool

)

[virtual]

Whether to trim whitespace from strings prior to conversion to a numeric. Default is false to preserve backward compatibility. vtkVariant handles whitespace inconsistently, so trim it before we try to convert it. For example: vtkVariant(" 2.0").ToDouble() == 2.0 <-- leading whitespace is not a problem vtkVariant(" 2.0 ").ToDouble() == NaN <-- trailing whitespace is a problem vtkVariant(" infinity ").ToDouble() == NaN <-- any whitespace is a problem In these cases, trimming the whitespace gives us the result we expect: 2.0 and INF respectively.

virtual bool vtkStringToNumeric::GetTrimWhitespacePriorToNumericConversion

(

)

[virtual]

Whether to trim whitespace from strings prior to conversion to a numeric. Default is false to preserve backward compatibility. vtkVariant handles whitespace inconsistently, so trim it before we try to convert it. For example: vtkVariant(" 2.0").ToDouble() == 2.0 <-- leading whitespace is not a problem vtkVariant(" 2.0 ").ToDouble() == NaN <-- trailing whitespace is a problem vtkVariant(" infinity ").ToDouble() == NaN <-- any whitespace is a problem In these cases, trimming the whitespace gives us the result we expect: 2.0 and INF respectively.

virtual void vtkStringToNumeric::TrimWhitespacePriorToNumericConversionOn

(

)

[virtual]
