COR_PRF_GC_GENERATION Enumeration

Identifies a garbage-collection generation.

typedef enum {
    COR_PRF_GC_GEN_0 = 0,
    COR_PRF_GC_GEN_1 = 1,
    COR_PRF_GC_GEN_2 = 2,
    COR_PRF_GC_LARGE_OBJECT_HEAP = 3
} COR_PRF_GC_GENERATION;

Members

Member	Description
COR_PRF_GC_GEN_0	The object is stored as generation 0.
COR_PRF_GC_GEN_1	The object is stored as generation 1.
COR_PRF_GC_GEN_2	The object is stored as generation 2.
COR_PRF_GC_LARGE_OBJECT_HEAP	The object is stored in the large-object heap.

Remarks

The garbage collector improves memory management performance by dividing objects into generations based on age. The garbage collector currently uses three generations, numbered 0, 1, and 2, plus a special heap segment that is used for large objects. Objects whose size is larger than a particular value are stored in the large-object heap. Other allocated objects start out belonging to generation 0. All objects that exist after garbage collection occurs in generation 0 are promoted to generation 1. Objects that exist after garbage collection occurs in generation 1 move into generation 2.

The use of generations means that the garbage collector has to work with only a subset of the allocated objects at any one time.

The COR_PRF_GC_GENERATION enumeration is used by the COR_PRF_GC_GENERATION_RANGE structure.
