Constructor Details

DyldCacheSlideInfo5

public DyldCacheSlideInfo5(BinaryReader reader,
 long mappingAddress,
 long mappingSize,
 long mappingFileOffset)
                    throws IOException

Create a new DyldCacheSlideInfo5.

Parameters:

reader - A BinaryReader positioned at the start of a DYLD slide info 5

mappingAddress - The base address of where the slide fixups will take place

mappingSize - The size of the slide fixups block

mappingFileOffset - The base file offset of where the slide fixups will take place

Throws:

IOException - if there was an IO-related problem creating the DYLD slide info 5

Method Details

getPageSize

public int getPageSize()

Returns The page size.

Returns:

The page size

getPageStartsCount

public int getPageStartsCount()

Returns The page starts count.

Returns:

The page starts count

getValueAdd

public long getValueAdd()

Returns The "value add".

Returns:

The "value add"

getPageStarts

public short[] getPageStarts()

Returns The page starts array.

Returns:

The page starts array

public List<DyldFixup> getSlideFixups(BinaryReader reader,
 int pointerSize,
 MessageLog log,
 TaskMonitor monitor)
                               throws IOException,
CancelledException

Description copied from class: DyldCacheSlideInfoCommon

Walks the slide fixup information and collects a List of DyldFixups that will need to be applied to the image

Specified by:

getSlideFixups in class DyldCacheSlideInfoCommon

Parameters:

reader - A BinaryReader positioned at the start of the segment to fix up

pointerSize - The size of a pointer in bytes

log - The log

monitor - A cancellable monitor

Returns:

A List of DyldFixups

Throws:

IOException - If there was an IO-related issue

CancelledException - If the user cancelled the operation

toDataType

public DataType toDataType()
                    throws DuplicateNameException,
IOException

Description copied from interface: StructConverter

Returns a structure datatype representing the contents of the implementor of this interface.

For example, given:

 class A {
     int foo;
     double bar;
 }
 

The return value should be a structure data type with two data type components; an INT and a DOUBLE. The structure should contain field names and, if possible, field comments.

Specified by:

toDataType in interface StructConverter

Overrides:

toDataType in class DyldCacheSlideInfoCommon

Returns:

returns a structure datatype representing the implementor of this interface

Throws:

DuplicateNameException - when a datatype of the same name already exists

IOException - if an IO-related error occurs
