Detailed Description

Field to encapsulate a float value.

Definition at line 388 of file mlFields.h.

Constructor & Destructor Documentation

◆ FloatField() [1/2]

ml::FloatField::FloatField ( )

default

Implements the runtime type system interface for this class.

Default constructor, do not use it.

◆ FloatField() [2/2]

ml::FloatField::FloatField ( const std::string & name )

explicit

Constructor; creates a field with a name to manage a float value with 0 as a default value.

Member Function Documentation

◆ getFloatValue()

float ml::FloatField::getFloatValue ( ) const

Returns the value of the field.

Referenced by ml::CSOGenerator::getDefaultPathPointAlpha(), ml::CSOGenerator::getDefaultPathPointWidth(), ml::CSOGenerator::getDefaultSeedPointAlpha(), ml::CSOGenerator::getDefaultSeedPointSize(), and ml::CSOGenerator::getDefaultVoxelWriteValue().

◆ getStringValue()

std::string ml::FloatField::getStringValue ( ) const

overridevirtual

Returns the value of the field as a string value.

setStringValue must be able to reinterpret this returned string correctly.

Implements ml::Field.

◆ getValue()

float ml::FloatField::getValue ( ) const

inline

Same as getFloatValue().

Definition at line 429 of file mlFields.h.

◆ setFloatValue()

void ml::FloatField::setFloatValue ( float floatValue )

Sets the field value to floatValue.

By default, the entire float type range can be set.

◆ setStringValue()

void ml::FloatField::setStringValue ( const std::string & stringValue )

overridevirtual

Sets the value of the field to stringValue.

Implements ml::Field.

◆ setValue()

void ml::FloatField::setValue ( float floatValue )

inline

Same as setFloatValue().

Definition at line 423 of file mlFields.h.

◆ setValueCallback()

static void ml::FloatField::setValueCallback	(	void *	field,
		double	value
	)

static

Callback method that can be used as a MLRequestProgressCB to set the progress to the field.

◆ setValueFromField()

void ml::FloatField::setValueFromField ( const Field & field )

overrideprotectedvirtual

Reimplementation from Field that copies the field value more efficiently.

Reimplemented from ml::Field.

◆ updateFloatValue()

void ml::FloatField::updateFloatValue ( float floatValue )

Sets the field value to floatValue, but only touches the field if the new value is different from the old value.

Note that values must be identical to avoid touching the field! By default, the entire float type range can be set.

◆ updateValue()

void ml::FloatField::updateValue ( float floatValue )

inline

Same as updateFloatValue().

Definition at line 426 of file mlFields.h.

Member Data Documentation

◆ _value

float ml::FloatField::_value {}

protected

The field value.
