public InMemoryRangeMapAdapter()

Method Details

clearRange

public void clearRange(Address start,
 Address end)

Description copied from interface: RangeMapAdapter

Clears all associated values in the given range.

Specified by:

clearRange in interface RangeMapAdapter

Parameters:

start - the first address in the range to clear.

end - the end address in the range to clear.

See Also:

• RangeMapAdapter.clearRange(ghidra.program.model.address.Address, ghidra.program.model.address.Address)

clearAll

public void clearAll()

Description copied from interface: RangeMapAdapter

Clears all values.

Specified by:

clearAll in interface RangeMapAdapter

See Also:

• RangeMapAdapter.clearAll()

getValueRangeContaining

public AddressRange getValueRangeContaining(Address addr)

Description copied from interface: RangeMapAdapter

Returns the bounding address-range containing addr and the same value throughout. This range will be limited by any value change associated with the base register.

Specified by:

getValueRangeContaining in interface RangeMapAdapter

Parameters:

addr - the containing address

Returns:

single value address-range containing addr

See Also:

• RangeMapAdapter.getValueRangeContaining(ghidra.program.model.address.Address)

getAddressRangeIterator

public AddressRangeIterator getAddressRangeIterator(Address start,
 Address end)

Description copied from interface: RangeMapAdapter

Returns an IndexRangeIterator over all stored values in the given range. If the given range intersects an actual stored range either at the beginning or end, the iterator will return those ranges truncated to fit within the given range.

Specified by:

getAddressRangeIterator in interface RangeMapAdapter

Parameters:

start - the first Address in the range.

end - the last Address (inclusive) index in the range.

Returns:

an IndexRangeIterator over all stored values.

See Also:

• RangeMapAdapter.getAddressRangeIterator(ghidra.program.model.address.Address, ghidra.program.model.address.Address)

getAddressRangeIterator

public AddressRangeIterator getAddressRangeIterator()

Description copied from interface: RangeMapAdapter

Returns an IndexRangeIterator over all stored values.

Specified by:

getAddressRangeIterator in interface RangeMapAdapter

Returns:

an IndexRangeIterator over all stored values.

See Also:

• RangeMapAdapter.getAddressRangeIterator()

getValue

public byte[] getValue(Address address)

Description copied from interface: RangeMapAdapter

Returns the byte array that has been associated with the given index.

Specified by:

getValue in interface RangeMapAdapter

Parameters:

address - the address at which to retrieve a byte array.

Returns:

the byte array that has been associated with the given index or null if no such association exists.

See Also:

• RangeMapAdapter.getValue(ghidra.program.model.address.Address)

set

public void set(Address start,
 Address end,
 byte[] bytes)

Description copied from interface: RangeMapAdapter

Associates the given byte array with all indexes in the given range. Any existing values will be over written.

Specified by:

set in interface RangeMapAdapter

Parameters:

start - the first address in the range.

end - the last Address(inclusive) in the range.

bytes - the bytes to associate with the range.

See Also:

• RangeMapAdapter.set(ghidra.program.model.address.Address, ghidra.program.model.address.Address, byte[])

moveAddressRange

public void moveAddressRange(Address fromAddr,
 Address toAddr,
 long length,
 TaskMonitor monitor)
                      throws CancelledException

Description copied from interface: RangeMapAdapter

Move all values within an address range to a new range.

Specified by:

moveAddressRange in interface RangeMapAdapter

Parameters:

fromAddr - the first address of the range to be moved.

toAddr - the address where to the range is to be moved.

length - the number of addresses to move.

monitor - the task monitor.

Throws:

CancelledException - if the user canceled the operation via the task monitor.

See Also:

• RangeMapAdapter.moveAddressRange(ghidra.program.model.address.Address, ghidra.program.model.address.Address, long, ghidra.util.task.TaskMonitor)

isEmpty

public boolean isEmpty()

Description copied from interface: RangeMapAdapter

Returns:

true if this storage has no associated values for any address

See Also:

• RangeMapAdapter.isEmpty()

checkWritableState

public void checkWritableState()

Description copied from interface: RangeMapAdapter
