Class Type
- All Implemented Interfaces:
Constants
,RuntimeConstants
- Direct Known Subclasses:
ArrayType
,ClassType
,MethodType
It encapsulates an Java type signature and it provides quick access to the components of the type. Note that all types are hashed into a hashtable (typeHash), that means that each distinct type is only allocated once, saving space and making equality checks cheap.
For simple types use the constants defined in this class. (Type.tInt, Type.tShort, ...). To create complex types use the static methods Type.tArray, Type.tMethod or Type.tClass. For classes, arrays and method types a sub class of class type is created which defines the extra type components. WARNING: The contents of this source file are not part of any supported API. Code that depends on them does so at its own risk: they are subject to change or removal without notice.

Type
Create a type given a typecode and a type signature.
-
-
Method Details
-
getTypeSignature
Return the Java type signature. -
getTypeCode
public final int getTypeCode()Return the type code. -
getTypeMask
public final int getTypeMask()Return the type mask. The bits in this mask correspond to the TM_* constants defined in Constants. Only one bit is set at a type.- See Also:
-
isType
public final boolean isType(int tc) Check for a certain type. -
isVoidArray
public boolean isVoidArray()Check to see if this is the bogus type "array of void" Although this highly degenerate "type" is not constructable from the grammar, the Parser accepts it. Rather than monkey with the Parser, we check for the bogus type at specific points and give a nice error. -
inMask
public final boolean inMask(int tm) Check for a certain set of types. -
tArray
Create an array type. -
getElementType
Return the element type of an array type. Only works for array types. -
getArrayDimension
public int getArrayDimension()Return the array dimension. Only works for array types. -
tClass
Create a class type. -
getClassName
Return the ClassName. Only works on class types. -
mangleInnerType
Given an inner identifier, return the non-inner, mangled representation used to manage signatures. Note: It is changed to 'public' for Jcov file generation. (see Assembler.java) -
changeClassName
We have learned that a signature means something other that what we thought it meant. Live with it: Change all affected data structures to reflect the new name of the old type.(This is necessary because of an ambiguity between the low-level signatures of inner types and their manglings. Note that the latter are also valid class names.)
-
tMethod
Create a method type with no arguments. -
tMethod
Create a method type with arguments. -
getReturnType
Return the return type. Only works for method types. -
getArgumentTypes
Return the argument types. Only works for method types. -
tType
Create a Type from an Java type signature.- Throws:
CompilerError
- invalid type signature.
-
equalArguments
Check if the type arguments are the same.- Returns:
- true if both types are method types and the argument types are identical.
-
stackSize
public int stackSize()Return the amount of space this type takes up on the Java operand stack. For a method this is equal to the total space taken up by the arguments. -
getTypeCodeOffset
public int getTypeCodeOffset()Return the type code offset. This offset can be added to an opcode to get the right opcode type. Most opcodes are ordered: int, long, float, double, array. For example: iload, lload fload, dload, aload. So the appropriate opcode is iadd + type.getTypeCodeOffset(). -
typeString
Convert a Type to a string, if abbrev is true class names are not fully qualified, if ret is true the return type is included. -
typeString
Create a type string, given an identifier. -
toString
Convert to a String -
toStringValue
-
