void ConstantArray::destroyConstant  )  [virtual]
 

destroyConstant - Called if some element of this constant is no longer valid. At this point only other constants may be on the use_list for this constant. Any constants on our Use list must also be destroy'd. The implementation must be sure to remove the constant from the list of available cached constants. Implementations should call destroyConstantImpl as the last thing they do, to destroy all users and delete this.

Reimplemented from llvm::Constant.

get() - Static factory methods - Return objects of the specified value

std::string ConstantArray::getAsString  )  const
 

getAsString - If this array is isString(), then this method converts the array to an std::string and returns it. Otherwise, it asserts out.

Definition at line 948 of file Constants.cpp.

References llvm::User::getNumOperands(), llvm::Constant::getOperand(), and isString().

Referenced by getStringValue().

const ArrayType* llvm::ConstantArray::getType  )  const [inline]
 

getType - Specialize the getType() method to always return an ArrayType, which reduces the amount of casting needed in parts of the compiler.

Reimplemented from llvm::Value.

Definition at line 362 of file Constants.h.

References llvm::Value::getType().

Referenced by ConstantArray(), llvm::ExecutionEngine::InitializeMemory(), isString(), isStringCompatible(), and replaceUsesOfWithOnConstant().

virtual bool llvm::ConstantArray::isNullValue  )  const [inline, virtual]
 

isNullValue - Return true if this is the value that would be returned by getNullValue. This always returns false because zero arrays are always created as ConstantAggregateZero objects.

Implements llvm::Constant.

Definition at line 378 of file Constants.h.

bool ConstantArray::isString  )  const
 

isString - This method returns true if the array is an array of sbyte or ubyte, and if the elements of the array are all ConstantInt's.

Definition at line 931 of file Constants.cpp.

References llvm::User::getNumOperands(), llvm::Constant::getOperand(), getType(), llvm::Type::SByteTy, and llvm::Type::UByteTy.

void ConstantArray::replaceUsesOfWithOnConstant Value From,
Value To,
bool  DisableChecking = false
[virtual]
 

replaceUsesOfWithOnConstant - This method is a special form of User::replaceUsesOfWith (which does not work on constants) that does work on constants. Basically this method goes through the trouble of building a new constant that is equivalent to the current one, with all uses of From replaced with uses of To. After this construction is completed, all of the users of 'this' are replaced to use the new constant, and then 'this' is deleted. In general, you should not call this method, instead, use Value::replaceAllUsesWith, which automatically dispatches to this method as needed.

Reimplemented from llvm::Constant.
