Constructor Detail

ExceptionHandlerFrameHeader

public ExceptionHandlerFrameHeader(TaskMonitor monitor,
                                   Program curProg)

Constructor for an ExceptionHandlerFrameHeader.

Parameters:

monitor - a status monitor for indicating progress or allowing a task to be cancelled.

curProg - the program containing this eh frame header.

Method Detail

addToDataTypeManager

public void addToDataTypeManager()

Adds the structure data type for the eh frame header to the program's data type manager.

create

public void create(Address addr)
            throws MemoryAccessException,
                   AddressOutOfBoundsException

Method that creates an Exception Handler Frame Header Structure at the address specified by 'addr'. If addr is 'null', this method returns without creating the structure.

Parameters:

addr - - Address at which the Exception Handler Frame Header Structure should be created.

Throws:

AddressOutOfBoundsException - if the memory needed for this frame header isn't in the program.

MemoryAccessException - if the memory needed for this frame header isn't in the program.

getLength

public int getLength()

Gets the length of the EH Frame Header.

Returns:

the length of this frame header.

getEh_FrameVersion

public int getEh_FrameVersion()

Gets the version for this program's eh frame.

Returns:

the version indicator.

getEh_FrameDescEntryCntEncoding

public int getEh_FrameDescEntryCntEncoding()

Gets the eh frame description entry count.

Returns:

the description entry count.

getEh_FramePtrEncoding

public int getEh_FramePtrEncoding()

Gets the eh frame pointer encoding.

Returns:

the pointer encoding.

getEh_FrameTableEncoding

public int getEh_FrameTableEncoding()

Gets the eh handler table encoding.

Returns:

the table encoding.
