## Member Typedef Documentation

### typedef ptrdiff\_t difference\_type` [inherited]`

Distance between iterators is represented as this type.

Definition at line 113 of file stl\_iterator\_base\_types.h.

### typedef std::random\_access\_iterator\_tag iterator\_category` [inherited]`

One of the **tag types**.

Definition at line 109 of file stl\_iterator\_base\_types.h.

### typedef bool \* pointer` [inherited]`

This type represents a pointer-to-value\_type.

Reimplemented in **\_Bit\_iterator**, and **\_Bit\_const\_iterator**.

Definition at line 115 of file stl\_iterator\_base\_types.h.

### typedef bool & reference` [inherited]`

This type represents a reference-to-value\_type.

Reimplemented in **\_Bit\_iterator**, and **\_Bit\_const\_iterator**.

Definition at line 117 of file stl\_iterator\_base\_types.h.

### typedef bool value\_type` [inherited]`

The type 'pointed to' by the iterator.

Definition at line 111 of file stl\_iterator\_base\_types.h.
