Constructor & Destructor Documentation

◆ FloatField() [1/2]

ml::FloatField::FloatField ( )

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 )

Constructor, create a field with a name to manage a float value, with 0 as a default value.

Member Function Documentation

◆ _initialize()

void ml::FloatField::_initialize	(	const std::string &	name = `""`,
		float *	valuePtr = `nullptr`
	)

protected

Initializes this field.

◆ 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 667 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 661 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 which 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 touch 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 664 of file mlFields.h.

Member Data Documentation

protected

Maximum float value which can be set.

Deprecated:

Definition at line 691 of file mlFields.h.

◆ _minValue

float ml::FloatField::_minValue

protected

Minimum float value which can be set.

Deprecated:

Definition at line 688 of file mlFields.h.

◆ _valuePtr

float* ml::FloatField::_valuePtr

protected

Points to the variable containing the field value.

Definition at line 681 of file mlFields.h.
