static bool	areNotificationsEnabledGlobally ()
	Returns whether the notification mechanism for all fields (e.g., when field values are set) is enabled (see enableNotificationsGlobally(bool) ) Usually it is false(=0) within all calls of Module::calc* methods to avoid that field changes within these methods recursively start the calculation process of the ML.

(

)

Implements the runtime type system interface for this class.

Default constructor, do not use it.

Constructor, creates a field with a name to manage a 4x4 matrix.

Default value is the unit matrix.

Member Function Documentation

getMatrix4Value()

const Matrix4 & ml::MatrixField::getMatrix4Value

(

)

const

Returns the value of the field; same as getMatrixValue for symmetry to other fields.

getMatrixValue()

const Matrix4 & ml::MatrixField::getMatrixValue

(

)

const

Returns the value of the field.

getStringValue()

std::string ml::MatrixField::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()

const Matrix4 & ml::MatrixField::getValue ( ) const

inline

Same as getMatrix4Value().

Definition at line 1659 of file mlFields.h.

setMatrix4Value()

void ml::MatrixField::setMatrix4Value

(

const Matrix4 &

matrixValue

)

Sets the value of the field to matrixValue; same as setMatrixValue for symmetry to other fields.

setMatrixValue()

void ml::MatrixField::setMatrixValue

(

const Matrix4 &

matrixValue

)

Sets the value of the field to matrixValue.

setStringValue()

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

overridevirtual

Sets the field value to stringValue="a11 a12 ... a44".

If less than 16 valid numbers can be scanned in string then all components are set to 0.

Implements ml::Field.

setValue()

void ml::MatrixField::setValue ( const Matrix4 & matrixValue )

inline

Same as setMatrix4Value().

Definition at line 1653 of file mlFields.h.

setValueFromField()

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

overrideprotectedvirtual

Reimplementation from Field which copies the field value more efficiently.

Reimplemented from ml::Field.

updateMatrix4Value()

void ml::MatrixField::updateMatrix4Value

(

const Matrix4 &

matrixValue

)

Sets the value of the field to matrixValue, 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!)

updateValue()

void ml::MatrixField::updateValue ( const Matrix4 & matrixValue )

inline

Same as updateMatrix4Value().

Definition at line 1656 of file mlFields.h.
