Equals()
Object::Equals(ptr) method
Compares objects using C# Object.Equals semantics.
virtual bool System::Object::Equals(ptr obj)
Arguments
| Parameter | Type | Description |
|---|---|---|
| obj | ptr | Object to compare current one to. |
Return Value
True if objects are considered equal and false otherwise.
Object::Equals(T1 const&, T2 const&) method
Compares reference type objects in C# style.
template<typename T1,typename T2> static std::enable_if<IsSmartPtr<T1>::value &&IsSmartPtr<T2>::value, bool>::type System::Object::Equals(T1 const &objA, T2 const &objB)
Template parameters
| Parameter | Description |
|---|---|
| T1 | Type of first object to compare. |
| T2 | Type of second object to compare. |
Arguments
| Parameter | Type | Description |
|---|---|---|
| objA | T1 const& | First object to compare. |
| objB | T2 const& | Second object to compare. |
Return Value
True if objects match either by reference or semantically (by Object.Equals-alike comparison), false otherwise.
Object::Equals(T1 const&, T2 const&) method
Compares value type objects in C# style.
template<typename T1,typename T2> static std::enable_if<!IsSmartPtr<T1>::value &&!IsSmartPtr<T2>::value, bool>::type System::Object::Equals(T1 const &objA, T2 const &objB)
Template parameters
| Parameter | Description |
|---|---|
| T1 | Type of first object to compare. |
| T2 | Type of second object to compare. |
Arguments
| Parameter | Type | Description |
|---|---|---|
| objA | T1 const& | First object to compare. |
| objB | T2 const& | Second object to compare. |
Return Value
True if objects are considered equal by equality operator available, false otherwise.
Object::Equals(float const&, float const&) method
Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
bool System::Object::Equals(float const &objA, float const &objB)
Arguments
| Parameter | Type | Description |
|---|---|---|
| objA | float const& | LHS floating point value. |
| objB | float const& | RHS floating point value. |
Return Value
True if objA and objB are both NaN or equal, false otherwise.
Object::Equals(double const&, double const&) method
Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
bool System::Object::Equals(double const &objA, double const &objB)
Arguments
| Parameter | Type | Description |
|---|---|---|
| objA | double const& | LHS floating point value. |
| objB | double const& | RHS floating point value. |
Return Value
True if objA and objB are both NaN or equal, false otherwise.
