◆ apply()

uint16_t roo_monitoring::Transform::apply ( float value ) const

Applies the transform and clamps to [0, 65535].

Definition at line 13 of file transform.cpp.

Referenced by roo_monitoring::WriteTransaction::write().

◆ Linear()

Transform roo_monitoring::Transform::Linear	(	float	multiplier,
		float	offset
	)

static

Creates a linear transformation ax+b.

The result is rounded to the nearest integer.

Definition at line 5 of file transform.cpp.

References multiplier(), and offset().

◆ LinearRange()

Transform roo_monitoring::Transform::LinearRange	(	float	min_value,
		float	max_value
	)

static

Creates a linear transform from min/max representable values.

The minimum maps to 0 and the maximum maps to 65535.

Definition at line 9 of file transform.cpp.

◆ multiplier()

float roo_monitoring::Transform::multiplier ( ) const

inline

Returns the multiplier used by the transform.

Definition at line 29 of file transform.h.

Referenced by Linear().

◆ offset()

float roo_monitoring::Transform::offset ( ) const

inline

Returns the offset used by the transform.

Definition at line 31 of file transform.h.

Referenced by Linear().

◆ unapply()

float roo_monitoring::Transform::unapply ( uint16_t value ) const

Recovers the application-domain value from encoded data.

Definition at line 24 of file transform.cpp.
