Default constructor, do not use it.

◆ BaseField() [2/2]

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

Member Function Documentation

◆ addAllowedType() [1/2]

Add type to list of allowed types.

This will set the Base value to NULL if it isn't 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.

◆ getAllowedTypes()

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

inline

Get list of allowed Base types for this field.

Definition at line 856 of file mlFields.h.

◆ getBaseValue()

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

Returns current field value.

◆ 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()

inline

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

Definition at line 877 of file mlFields.h.

Definition at line 869 of file mlFields.h.

◆ hasUnallowedType()

bool ml::BaseField::hasUnallowedType ( ) const

inline

return true if the last call of setBaseValue had an unallowed type as argument, getBaseValue will return NULL then

Definition at line 860 of file mlFields.h.

◆ setBaseValue() [1/2]

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

Sets the value of the field to basePointerValue.

◆ setBaseValue() [2/2]

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 853 of file mlFields.h.

References 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! (Or you might specify the type as template argument for NULL arguments!)
