Detailed Description

A contiguous range of bytes in some address space.

Constructor & Destructor Documentation

Range::Range ( AddrSpace *  s, uintb  f, uintb  l  )

inline

Construct a Range from offsets.

Offsets must expressed in bytes as opposed to addressable words

Parameters

s	is the address space containing the range
f	is the offset of the first byte in the range
l	is the offset of the last byte in the range

Member Function Documentation

bool Range::contains ( const Address &  addr ) const

inline

Determine if the address is in this Range.

Parameters

addr	is the Address to test for containment

Returns

true if addr is in this Range

References Address::getOffset(), and Address::getSpace().

Address Range::getLastAddrOpen

(

const AddrSpaceManager *

manage

)

const

Get address of first byte after this.

Get the last address +1, updating the space, or returning the extremal address if necessary

Parameters

manage

is used to fetch the next address space

bool Range::operator< ( const Range &  op2 ) const

inline

Sorting operator for Ranges.

Compare based on address space, then the starting offset

Parameters

op2	is the Range to compare with this

Returns

true if this comes before op2

void Range::printBounds

(

ostream &

s

)

const

Print this Range to a stream.

Output a description of this Range like: ram: 7f-9c

Parameters

s	is the output stream

void Range::restoreXml	(	const Element *	el,
		const AddrSpaceManager *	manage
	)

Restore this from XML stream.

Reconstruct this object from an XML <range> element

Parameters

el	is the XML element
manage	is the space manage for recovering AddrSpace objects

void Range::saveXml

(

ostream &

s

)

const

Save this Range to an XML stream.

Write this object to a stream as a <range> tag.

Parameters

s	is the output stream
