Constructor Details

DyldCacheSlideInfo1

public DyldCacheSlideInfo1(BinaryReader reader,
 DyldCacheMappingInfo mappingInfo)
                    throws IOException

Create a new DyldCacheSlideInfo1.

Parameters:

reader - A BinaryReader positioned at the start of a DYLD slide info 1

mappingInfo - The DyldCacheMappingInfo of where the slide fixups will take place

Throws:

IOException - if there was an IO-related problem creating the DYLD slide info 1

Method Details

getTocOffset

public int getTocOffset()

Returns The TOC offset.

Returns:

The TOC offset

getTocCount

public int getTocCount()

Returns The TOC count.

Returns:

The TOC count

getEntriesOffset

public int getEntriesOffset()

Returns The entries offset.

Returns:

The entries offset

getEntriesCount

public int getEntriesCount()

Returns The entries count.

Returns:

The entries count

getEntriesSize

public int getEntriesSize()

Returns The entries size.

Returns:

The entries size

getToc

public short[] getToc()

Returns The TOC.

Returns:

The TOC

getEntries

public byte[][] getEntries()

Returns The entries.

Returns:

The entries

getSlideFixups

 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
