Detailed Description

Class wich represents an ELF Section.

Member Function Documentation

◆ accept()

void LIEF::ELF::Section::accept ( Visitor & visitor ) const

overridevirtual

Implements LIEF::Object.

◆ content() [1/2]

span< const uint8_t > LIEF::ELF::Section::content ( ) const

overridevirtual

Section's content.

Reimplemented from LIEF::Section.

◆ content() [2/2]

void LIEF::ELF::Section::content ( const std::vector< uint8_t > & data )

overridevirtual

Set section content.

Reimplemented from LIEF::Section.

◆ entry_size()

uint64_t LIEF::ELF::Section::entry_size ( ) const

This function returns the size of an element in the case of a section that contains an array.

For instance, the .dynamic section contains an array of DynamicEntry. As the size of the raw C structure of this entry is 0x10 (sizeof(Elf64_Dyn)) in a ELF64, the entry_size is set to this value.

◆ file_offset()

uint64_t LIEF::ELF::Section::file_offset ( ) const

See also: offset

◆ has()

bool LIEF::ELF::Section::has ( ELF_SECTION_FLAGS flag ) const

True if the section has the given flag

Parameters

[in] flag flag to test

◆ offset() [1/2]

uint64_t LIEF::ELF::Section::offset ( ) const

overridevirtual

Offset in the binary.

Reimplemented from LIEF::Section.

◆ offset() [2/2]

void LIEF::ELF::Section::offset ( uint64_t offset )

overridevirtual

Reimplemented from LIEF::Section.

◆ original_size()

uint64_t LIEF::ELF::Section::original_size ( ) const

Original size of the section's data.

This value is used by the ELF::Builder to determines if it needs to be relocated to avoid an override of the data

◆ size() [1/2]

uint64_t LIEF::ELF::Section::size ( ) const

overridevirtual

section's size (size in the binary, not the virtual size)

Reimplemented from LIEF::Section.

◆ size() [2/2]

void LIEF::ELF::Section::size ( uint64_t size )

overridevirtual

Change the section size.

Reimplemented from LIEF::Section.
