char ExtentMap::category	(	const Extent &	a,
		const Extent &	b
	)			[static]

Class method comparing two extents.

The return value is one of the following letters, depending on how extent A is related to extent B: C (congruent): A and B are congruent L (left): A is left of B R (right): A is right of B O (outer): A contains B, but A and B are not congruent I (inner): A is contained by B, but A and B are not congruent B (beginning): A overlaps with the beginning of B but does not contain B E (ending): A overlaps with the end of B but does not contain B

)

Allocate the specified extent, which must be in the free list.

Extent ExtentMap::allocate_best_fit

(

const rose_addr_t

size

)

Allocate an extent of the specified size (best fit first) from the extent map, removing the returned extent from the map.

Extent ExtentMap::allocate_first_fit

(

const rose_addr_t

size

)

Allocate an extent of the specified size (first fit) from the extent map, removing the returned extent from the map.

void ExtentMap::dump_extents	(	FILE *	f,
		const char *	prefix,
		const char *	label,
		bool	pad = true
	)			const

Print info about an extent map.

This is a little different format than the ostream "<<" operator.
