Reference to a function, basic block, instruction, or address.
A reference can be an empty reference, or it points to a function and/or basic block and/or instruction, or it is an address in any combination. A reference has a granularity depending on the finest thing to which it points (see granularity). All non-empty references have a computable address regardless of whether an address is actually stored. References are comparable.

| Rose::BinaryAnalysis::Partitioner2::Reference::Reference | ( | ) |
Constructor.
A reference can be constructed from any combination of a function, basic block, instruction, and address.
| Granularity Rose::BinaryAnalysis::Partitioner2::Reference::granularity | ( | ) | const |
Reference granularity.
Returns the granularity for the reference. The granularity is the finest thing stored in the reference. The order from finest to coarsest is: EMPTY, ADDRESS, INSTRUCTION, BASIC_BLOCK, FUNCTION.
| bool Rose::BinaryAnalysis::Partitioner2::Reference::isEmpty | ( | ) | const |
Predicate for emptiness.
Returns true if this reference points to nothing and has no stored address.
| bool Rose::BinaryAnalysis::Partitioner2::Reference::hasFunction | ( | ) | const |
Predicate for having a function.
Returns true if the reference points to a function.
| bool Rose::BinaryAnalysis::Partitioner2::Reference::hasBasicBlock | ( | ) | const |
Predicate for having a basic block.
Returns true if the reference points to a basic block.
| bool Rose::BinaryAnalysis::Partitioner2::Reference::hasInstruction | ( | ) | const |
Predicate for having an instruction.
Returns true if the reference points to an instruction.
| bool Rose::BinaryAnalysis::Partitioner2::Reference::hasExplicitAddress | ( | ) | const |
Predicate for having a stored address.
All non-empty references have a computable address, but an address can also be stored explicitly. This predicate returns true when an address is stored explicitly.
| rose_addr_t Rose::BinaryAnalysis::Partitioner2::Reference::address | ( | ) | const |
Address.
All non-empty references have either an explicitly stored address or an address that can be obtained from an instruction, basic block, or function. This method returns the first address found from that list.
| bool Rose::BinaryAnalysis::Partitioner2::Reference::operator== | ( | const Reference & | other | ) | const |
Whether two references are equal.
Two references are equal if they are both empty, or else if they have the same address and granularity.
| bool Rose::BinaryAnalysis::Partitioner2::Reference::operator< | ( | const Reference & | other | ) | const |
Compare two references.
Returns true when this reference is less than the other reference. The empty reference is less than all non-empty references. A non-empty reference is less than or greater than another non-empty reference if its address is less than or greater than the other reference's address. When two references have the same address then the finer granularity reference is less than the coarser reference.
