Constructor Details

DBTraceDefinedUnitsView

public DBTraceDefinedUnitsView(DBTraceCodeSpace space)

Construct the view

Parameters:

space - the space, bound to an address space

Method Details

coversRange

public boolean coversRange(Lifespan span,
 AddressRange range)

Description copied from interface: TraceBaseCodeUnitsView

Check if the given span of snaps and range of addresses is covered by the units

This checks if every (snap, address) point within the given box is contained within some code unit in this view.

Specified by:

coversRange in interface TraceBaseCodeUnitsView<TraceCodeUnit>

Specified by:

coversRange in class AbstractBaseDBTraceCodeUnitsView<AbstractDBTraceCodeUnit<?>>

Parameters:

span - the span of snaps

range - the address range

Returns:

true if covered, false otherwise

See Also:

• TraceBaseCodeUnitsView.coversRange(Lifespan, AddressRange)

intersectsRange

public boolean intersectsRange(Lifespan span,
 AddressRange range)

Description copied from interface: TraceBaseCodeUnitsView

Check if the given span of snaps and range of addresses intersects any unit

This checks if any (snap, address) point within the given box is contained within some code unit in this view.

Specified by:

intersectsRange in interface TraceBaseCodeUnitsView<TraceCodeUnit>

Specified by:

intersectsRange in class AbstractBaseDBTraceCodeUnitsView<AbstractDBTraceCodeUnit<?>>

Parameters:

span - the span of snaps

range - the address range

Returns:

true if intersecting, false otherwise

See Also:

• TraceBaseCodeUnitsView.intersectsRange(Lifespan, AddressRange)

clear

public void clear(Lifespan span,
 AddressRange range,
 boolean clearContext,
 TaskMonitor monitor)
           throws CancelledException

Description copied from interface: TraceBaseDefinedUnitsView

Clear the units contained within the given span and address range.

Any units alive before the given span are truncated instead of deleted. That is, their end snaps are reduced such that they no longer intersect the given span. Note that the same is not true of a unit's start snap. If the start snap is contained in the span, the unit is deleted, even if its end snap is outside the span.

Specified by:

clear in interface TraceBaseDefinedUnitsView<TraceCodeUnit>

Parameters:

span - the span to clear

range - the range to clear

clearContext - true to clear the register context as well

monitor - a monitor for progress and cancellation

Throws:

CancelledException - if the clear is cancelled
