public abstract class Type
extends Object

Holds the type of a Value and also defines possible operations. Classes extended from this type will have to define the individual operation that are defined on those types. e.g. addition operation may be defined for the integer type.

Method Summary

Value	addressOf(Value var1, ByteOrder order, int wordSize) Evaluates the address of a variable.
boolean	completeFollowSym(String incomplete, List candidates) Complete the type's next token; return false if nothing completed.
boolean	completeMember(String incomplete, List candidates) Complete the type's member; return false if nothing completed.
Value	dereference(Value var1, ByteBuffer taskMem) Implements dereference operation for a pointer type.
ArithmeticUnit	getALU(ArrayType type, int wordSize)
ArithmeticUnit	getALU(FloatingPointType type, int wordSize)
ArithmeticUnit	getALU(int wordSize)
ArithmeticUnit	getALU(IntegerType type, int wordSize)
ArithmeticUnit	getALU(PointerType type, int wordSize)
ArithmeticUnit	getALU(Type type, int wordSize)
String	getName()
int	getSize()
Type	getSliceType() Get the type of slice.
Type	getType() Return the element type for array or pointer type.
Type	getUltimateType() Return the ultimate type (ignoring any decorator and other attributes).
Value	index(Value var1, Value var2, ByteBuffer taskMem) Implements subscript operation for a pointer or array type.
Value	member(Value var1, String member) Implements dot operation on a composite type.
Type	pack(int bitSize, int bitOffset) Pack this TYPE into bigSize and bitOffset.
Value	slice(Value var, Value i, Value j, ByteBuffer taskMem) Implements slice operation for a pointer or array type - slice the array from index I to index J.
String	toPrint() Print this Type to a StringBuffer and return the String.
abstract void	toPrint(StringBuilder stringBuilder, int indent) Print this Type after indenting INDENT spaces.
void	toPrintBrief(StringBuilder stringBuilder, int indent) Print this Type, possibly briefly, after indenting INDENT spaces.
String	toString() For debugging and tracing; just dump the Type's name.
