Constructor Detail

DyldCacheMappingInfo

public DyldCacheMappingInfo(BinaryReader reader)
                     throws java.io.IOException

Create a new DyldCacheImageInfo.

Parameters:

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

Throws:

java.io.IOException - if there was an IO-related problem creating the DYLD mapping info

Method Detail

getAddress

public long getAddress()

Gets the address of the start of the mapping.

Returns:

The address of the start of the mapping

getSize

public long getSize()

Gets the size of the mapping.

Returns:

The size of the mapping

getFileOffset

public long getFileOffset()

Gets the file offset of the start of the mapping.

Returns:

The file offset of the start of the mapping

isRead

public boolean isRead()

Returns true if the initial protections include READ.

Returns:

true if the initial protections include READ

isWrite

public boolean isWrite()

Returns true if the initial protections include WRITE.

Returns:

true if the initial protections include WRITE

isExecute

public boolean isExecute()

Returns true if the initial protections include EXECUTE.

Returns:

true if the initial protections include EXECUTE

contains

public boolean contains(long addr)

Returns true if the mapping contains the given address

Parameters:

addr - The address to check

Returns:

True if the mapping contains the given address; otherwise, false

toDataType

public DataType toDataType()

                           java.io.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

Returns:

returns a structure datatype representing the implementor of this interface

Throws:

DuplicateNameException - when a datatype of the same name already exists

java.io.IOException
