Parameters
Type Name Description
bool A_0

Equals(object)

Checks whether this GSChangesIterator is the same as the given object.

Declaration
public bool Equals(object o)
Parameters
Type Name Description
object o

a given object

Returns
Type Description
bool

true if equals to the give object

~GSChangesIterator()

Allows a GSChangesIterator to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Declaration
protected ~GSChangesIterator()

HasNext()

GSChangesIterator r

the GSChangesIterator on the right of the operator

Returns
Type Description
bool

true if both objects are equal

operator !=(GSChangesIterator, GSChangesIterator)

Inequality operator checks whether two GSChangesIterator are different

Declaration
public static bool operator !=(GSChangesIterator l, GSChangesIterator r)
Parameters
Type Name Description
