Class AddressMapImpl

java.lang.Object

ghidra.program.model.address.AddressMapImpl

public class AddressMapImpl
extends java.lang.Object

AddressMapImpl provides a stand-alone AddressMap. An AddressMapImpl instance should only be used to decode keys which it has generated. If this map is used for a specific program instance, the map should be discard if any changes are made to that programs address map (e.g., removing or renaming overlay spaces).

Constructor Detail

AddressMapImpl

public AddressMapImpl()

Creates a new AddressMapImpl with a mapID of 0.

AddressMapImpl

public AddressMapImpl(byte mapID,
                      AddressFactory addrFactory)

Creates a new AddressMapImpl with the specified mapID

Parameters:

mapID - the 8-bit value is placed in the upper 8 bits of every address encoding.

Method Detail

decodeAddress

public Address decodeAddress(long value)

See Also:

AddressMap.decodeAddress(long)

getKey

public long getKey(Address addr)

Generate a unique key for the specified addr. Only addresses from a single address space or single program should be passed to this method. Only limited checking is not performed in order to improve performance.

Parameters:

addr - address

See Also:

AddressMap.getKey(Address, boolean)

findKeyRange

public int findKeyRange(java.util.List<KeyRange> keyRangeList,
                        Address addr)

See Also:

AddressMap.findKeyRange(List, Address)

getKeyRanges

public java.util.List<KeyRange> getKeyRanges(Address start,
                                             Address end)

See Also:

AddressMap.getKeyRanges(Address, Address, boolean)

getKeyRanges

public java.util.List<KeyRange> getKeyRanges(AddressSetView set)

See Also:

AddressMap.getKeyRanges(AddressSetView, boolean)

reconcile

public void reconcile()

Reconcile address space changes using associated address factory. This method should be invoked following an undo/redo (if the associated address factory may have changed) or removal of an overlay memory block.
