#include <Value.h>
Detailed Description
LLVM Value Representation.
This is a very important LLVM class. It is the base class of all values computed by a program that may be used as operands to other values. Value is the super class of other important classes such as Instruction and Function. All Values have a Type. Type is not a subclass of Value. Some values can have a name and they belong to some Module. Setting the name on the Value automatically updates the module's symbol table.
Every value has a "use list" that keeps track of which other Values are using this Value. A Value can also have an arbitrary number of ValueHandle objects that watch it and listen to RAUW and Destroy events. See llvm/Support/ValueHandle.h for details.
Member Typedef Documentation
| typedef value_use_iterator<const User> llvm::Value::const_use_iterator |
Member Enumeration Documentation
| enum llvm::Value::ValueTy |
An enumeration for keeping track of the concrete subclass of Value that is actually instantiated. Values of this enumeration are kept in the Value classes SubclassID field. They are used for concrete type identification.

| unsigned llvm::Value::getValueID | ( | ) | const [inline] |
getValueID - Return an ID for the concrete type of this object. This is used to implement the classof checks. This should not be used for any other purpose, as the values may change as LLVM evolves. Also, note that for instructions, the Instruction's opcode is added to InstructionVal. So this means three things: # there is no value with code InstructionVal (no opcode==0). # there are more possible values for the value type than in ValueTy enum. # the InstructionVal enumerator must be the highest valued enumerator in the ValueTy enum.
