Constructor Details

DWARFIndirectTable

public DWARFIndirectTable(BinaryReader reader,
 Function<DWARFCompilationUnit,Long> baseOffsetFunc)

Creates a DWARFIndirectTable

Parameters:

reader - BinaryReader containing the DWARFIndirectTableHeaders

baseOffsetFunc - a function that will return the baseoffset value for a DWARFCompilationUnit.

Method Details

bootstrap

public void bootstrap(String msg,
 DWARFIndirectTable.CheckedIOFunction<BinaryReader,? extends DWARFIndirectTableHeader> headerReader,
 TaskMonitor monitor)
               throws CancelledException,
IOException

Populates this instance will all DWARFIndirectTableHeader instances that can be read from the stream.

Parameters:

msg - String message to use for the taskmonitor

headerReader - a function that reads the specific table header type from the stream

monitor - TaskMonitor

Throws:

CancelledException - if cancelled

IOException - if error reading a header

getOffset

public long getOffset(int index,
 DWARFCompilationUnit cu)
               throws IOException

Returns the offset of an item, based on its index in a particular header (which is found by the controlling CU)

Parameters:

index - index of the item

cu - DWARFCompilationUnit

Returns:

long offset of the item. Caller responsible for reading the item themselves

Throws:

IOException - if error reading table data

clear

public void clear()
