Constructor Detail

ElfSymbolTable

public ElfSymbolTable()

DO NOT USE THIS CONSTRUCTOR, USE create*(GenericFactory ...) FACTORY METHODS INSTEAD.

Method Detail

isDynamic

public boolean isDynamic()

Returns true if this is the dynamic symbol table

Returns:

true if this is the dynamic symbol table

getStringTable

public ElfStringTable getStringTable()

Returns the associated string table section.

Returns:

the associated string table section

getSymbolCount

public int getSymbolCount()

Returns:

number of symbols

getSymbols

public ElfSymbol[] getSymbols()

Returns all of the symbols defined in this symbol table.

Returns:

all of the symbols defined in this symbol table

getSymbolIndex

public int getSymbolIndex(ElfSymbol symbol)

Returns the index of the specified symbol in this symbol table.

Parameters:

symbol - the symbol

Returns:

the index of the specified symbol

getSymbolAt

public ElfSymbol getSymbolAt(long addr)

Returns the symbol at the specified address.

Parameters:

addr - the symbol address

Returns:

the symbol at the specified address

getGlobalSymbols

public ElfSymbol[] getGlobalSymbols()

Returns all of the global symbols.

Returns:

all of the global symbols

getSourceFiles

public java.lang.String[] getSourceFiles()

Returns all of the sources file names.

Returns:

all of the sources file names

addSymbol

public void addSymbol(ElfSymbol symbol)

Adds the specified symbol into this symbol table.

Parameters:

symbol - the new symbol to add

toBytes

public byte[] toBytes(DataConverter dc)

Description copied from interface: ByteArrayConverter

Returns a byte array representing this implementor of this interface.

Specified by:

toBytes in interface ByteArrayConverter

Parameters:

dc - the data converter to use

Returns:

a byte array representing this object

See Also:

ByteArrayConverter.toBytes(ghidra.util.DataConverter)

getLength

public long getLength()

Description copied from interface: ElfFileSection

Length of file section in bytes

Specified by:

getLength in interface ElfFileSection

Returns:

length of file section in bytes

getAddressOffset

public long getAddressOffset()

Description copied from interface: ElfFileSection

Preferred memory address offset where data should be loaded. The returned offset will already have the prelink adjustment applied, although will not reflect any change in the image base.

Specified by:

getAddressOffset in interface ElfFileSection

Returns:

default memory address offset where data should be loaded

getTableSectionHeader

public ElfSectionHeader getTableSectionHeader()

Get the section header which corresponds to this table, or null if only associated with a dynamic table entry

Returns:

symbol table section header or null

getFileOffset

public long getFileOffset()

Description copied from interface: ElfFileSection

Offset within file where section bytes are specified

Specified by:

getFileOffset in interface ElfFileSection

Returns:

offset within file where section bytes are specified

getEntrySize

public int getEntrySize()

Description copied from interface: ElfFileSection

Size of each structured entry in bytes

Specified by:

getEntrySize in interface ElfFileSection

Returns:

entry size or -1 if variable

toDataType

public DataType toDataType()
                    throws DuplicateNameException

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
