Detailed Description
template<class valuetype>
class scalar< valuetype >
The scalar class allows you to store a single value.
Constructor & Destructor Documentation
◆ scalar() [1/3]
Creates an instance of the scalar class.
◆ scalar() [2/3]
Creates an instance of the scalar class that is a copy of "a".
◆ scalar() [3/3]
|
inline |
Creates an instance of the scalar class that is a copy of "a".
◆ ~scalar()
Deletes this instance of the scalar class.
Member Function Documentation
◆ clear()
Removes the value currently stored in this instance, such that getValue() will return NULL or 0.
The value is only deleted if setManageValues(true) or setManageArrayValues(true) has been called.
Always returns true.
Implements collection.
◆ getReference()
|
inlinevirtual |
Returns a reference to the value stored in this instance.
Implements scalarcollection< valuetype >.
◆ getValue()
|
inlinevirtual |
Returns the value stored in this instance. Returns NULL or 0 if no value has been stored.
Implements scalarcollection< valuetype >.
◆ operator=() [1/2]
|
inline |
Makes this instance of the scalar class identical to "a".
◆ operator=() [2/2]
|
inline |
Makes this instance of the scalar class identical to "a".
◆ setValue()
|
inlinevirtual |
Sets the value stored in this instance to "v".
Implements scalarcollection< valuetype >.
