Method Detail

getNameOffset

public int getNameOffset()

The offset from the start of the section name table to the name of this section. A value of -1 indicates an unnamed section.

Returns:

the offset from the start of the section name table

getName

public java.lang.String getName()

Returns the name of this section.

Returns an input stream to underlying bytes of this section.

Returns:

an input stream to underlying bytes of this section

Throws:

java.io.IOException - if an i/o error occurs.

getUnpackedData

public byte[] getUnpackedData(TaskMonitor monitor)

Returns the size in bytes of the "initialized" part of the contents.

Returns:

the size in bytes of the "initialized" part of the contents

getContainerLength

public int getContainerLength()

Returns the size in bytes of the raw data in the container.

Returns:

the size in bytes of the raw data in the container

getContainerOffset

getSectionKind

public SectionKind getSectionKind()

getShareKind

public SectionShareKind getShareKind()

getAlignment

public byte getAlignment()

getReservedA

public byte getReservedA()

Reserved!

Returns:

Reserved!

isRead

public boolean isRead()

Returns true if this section has read permissions.

Returns:

true if this section has read permissions

isWrite

public boolean isWrite()

Returns true if this section has write permissions.

Returns:

true if this section has write permissions

isExecute

public boolean isExecute()

Returns true if this section has execute permissions.

Returns:

true if this section has execute permissions

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toDataType

public DataType toDataType()
                    throws DuplicateNameException,
                           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
