Detailed Description

Field to encapsulate a pointer to an ML base object.

Constructor & Destructor Documentation

◆ BaseField() [1/2]

ml::BaseField::BaseField ( )
default

Implements the runtime type system interface for this class.

Default constructor, do not use it.

Referenced by ml::TypedBaseField< T >::TypedBaseField().

◆ BaseField() [2/2]

ml::BaseField::BaseField ( const std::string & name)
explicit

Constructor; creates a field with a name to manage a base pointer. Default value is NULL.

◆ ~BaseField()

ml::BaseField::~BaseField ( )
override

Destructor.

Member Function Documentation

◆ addAllowedType() [1/2]

template<typename T>
void ml::BaseField::addAllowedType ( )
inline

Same as above, with template parameter where the Base type can be specified directly.

Definition at line 774 of file mlFields.h.

References addAllowedType().

Referenced by addAllowedType().

◆ addAllowedType() [2/2]

void ml::BaseField::addAllowedType ( const RuntimeType * allowedType)

Adds type to the list of allowed types. This will set the Base value to NULL if it is not NULL already and should only be called when creating the BaseField. Calls to setBaseValue (or setStringValue) will only succeed if the given Base object is of one of the allowed types or NULL, or if the list is empty; otherwise, NULL will be set instead.

Referenced by setBaseValueAndAddAllowedType(), and ml::TypedBaseField< T >::TypedBaseField().

◆ getAllowedTypes()

std::vector< const RuntimeType * > ml::BaseField::getAllowedTypes ( ) const
inline

Returns a list of allowed Base types for this field.

Definition at line 788 of file mlFields.h.

◆ getBaseValue()

Base * ml::BaseField::getBaseValue ( ) const

Returns current field value.

Referenced by getValue().

◆ getStringValue()

std::string ml::BaseField::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.

◆ getTypedBaseValue()

template<class Type>
Type ml::BaseField::getTypedBaseValue ( ) const
inline

Returns the typed value if the contained base object is derived from the given Type.

Definition at line 809 of file mlFields.h.

References getValue(), and mlbase_cast().

◆ getTypedValue()

template<class Type>
Type ml::BaseField::getTypedValue ( ) const
inline

Returns the typed value if the contained base object is derived from the given Type.

Definition at line 805 of file mlFields.h.

References getValue(), and mlbase_cast().

Referenced by ml::TypedBaseField< T >::getValue().

◆ getValue()

Base * ml::BaseField::getValue ( ) const
inline

Same as getBaseValue().

Definition at line 801 of file mlFields.h.

References getBaseValue().

Referenced by getTypedBaseValue(), and getTypedValue().

◆ hasUnallowedType()

bool ml::BaseField::hasUnallowedType ( ) const
inline

Returns true if the last call of setBaseValue had a not allowed type as argument, getBaseValue will return NULL then.

Definition at line 792 of file mlFields.h.

◆ setBaseValue() [1/2]

void ml::BaseField::setBaseValue ( Base * basePointerValue)

Sets the value of the field to basePointerValue.

Referenced by setBaseValueAndAddAllowedType(), setValue(), setValue(), and ml::TypedBaseField< T >::setValue().

◆ setBaseValue() [2/2]

void ml::BaseField::setBaseValue ( const RefCountedBasePtr & value)

Sets the value from intrusive pointer.

◆ setBaseValueAndAddAllowedType() [1/2]

template<typename T>
void ml::BaseField::setBaseValueAndAddAllowedType ( const ::boost::intrusive_ptr< T > & value)
inline

Convenience routine for setting the base value and its type at the same time using an intrusive pointer. See above methods for details.

Definition at line 785 of file mlFields.h.

References setBaseValueAndAddAllowedType().

Referenced by setBaseValueAndAddAllowedType().

◆ setBaseValueAndAddAllowedType() [2/2]

template<typename T>
void ml::BaseField::setBaseValueAndAddAllowedType ( T * value)
inline

Convenience routine for setting the base value and its type at the same time. The type is evaluated at compile-time, so even NULL works if it is cast to the right pointer type! Alternatively, you might specify the type as template argument for NULL arguments!

Definition at line 780 of file mlFields.h.

Referenced by ml::FieldContainer::addBaseWithAllowedType().

◆ setStringValue()

void ml::BaseField::setStringValue ( const std::string & stringValue)
overridevirtual

Sets pointer value from string stringValue. If string cannot be parsed successfully, a NULL pointer is set.

Implements ml::Field.

◆ setValue() [1/2]

void ml::BaseField::setValue ( Base * basePointerValue)
inline

Same as setBaseValue(Base*).

Definition at line 795 of file mlFields.h.

inline

Same as setBaseValue(const RefCountedBasePtr&).

◆ setValueFromField()

void ml::BaseField::setValueFromField ( const Field & field)
overrideprotectedvirtual

Reimplementation from Field that copies the field value more efficiently.

Reimplemented from ml::Field.
