Optionally bound relative virtual address.
A relative virtual address (RVA) is an address which is an offset from the file's base address. The file's base address is normally found in a file header structure.
This object stores an RVA as either the offset from the file's base address, or as an offset from a specified section's preferred mapping virtual address. The latter case is useful when a section's address might change later.

Static Public Member Functions | |
| static RelativeVirtualAddress | sectionRelative (SgAsmGenericSection *, rose_addr_t sectionOffset) |
| Constructs a new instance from a section and offset. | |

| Rose::BinaryAnalysis::RelativeVirtualAddress::RelativeVirtualAddress | ( | const rose_addr_t | rva, |

| ) |
Conversion from numeric RVA.
The new instance is constructed with the specified RVA and section. The rva is relative to the base address of the file header. The section is optional, and if present then the new instance is bound to that section.
|
static |
Constructs a new instance from a section and offset.
The RVA is computed by adding the specified offset to the section's preferred mapping address. The returned instance is bound to the section, which must not be null.
| rose_addr_t Rose::BinaryAnalysis::RelativeVirtualAddress::rva | ( | ) | const |
Returns the offset.
The returned value is an address relative to a base address stored in a (implied) file header. The file header is not actually referenced, thus this instance may be unbound.

| RelativeVirtualAddress & Rose::BinaryAnalysis::RelativeVirtualAddress::rva | ( | rose_addr_t | rva | ) |
Assign a new RVA without adjusting the bound section.
This object will store the new RVA. The binding to a section is not modified by this function.
| RelativeVirtualAddress & Rose::BinaryAnalysis::RelativeVirtualAddress::bindSection | ( | SgAsmGenericSection * | ) |
Changes the section binding.
This RVA is unbound from its previous section and bound to the new section. The numeric value of this RVA does not change as a result. If not null, the new_section must have a preferred mapping address.
| RelativeVirtualAddress & Rose::BinaryAnalysis::RelativeVirtualAddress::bindBestSection | ( | SgAsmGenericHeader * | ) |
Binds this RVA to the best available section from the specified file header.
The numeric value of the RVA is not changed by this operation. The section is selected to be the mapped section that most specifically includes this RVA.
| Sawyer::Optional< rose_addr_t > Rose::BinaryAnalysis::RelativeVirtualAddress::va | ( | ) | const |
Return the absolute address if known.
The absolute address is created by adding this RVA's numeric value to the base address associated with the bound section.
| Sawyer::Optional< rose_addr_t > Rose::BinaryAnalysis::RelativeVirtualAddress::boundOffset | ( | ) | const |
Returns an offset from the currently bound section.
Returns this address with respect to the beginning of the bound section. If no section is bound then nothing is returned.
| rose_addr_t Rose::BinaryAnalysis::RelativeVirtualAddress::offsetFrom | ( | SgAsmGenericSection * | ) | const |
Returns an offset relative to the specified section.
The specified section must be mapped to a VA.
| std::string Rose::BinaryAnalysis::RelativeVirtualAddress::toString | ( | ) | const |
Convert to a string representation.
If this RVA is unbound, then the string representation is the numeric RVA value (in hexadecimal and decimal). Otherwise the string representation contains information about the bound section.
