Method Detail

initializeConversions

public static final int[] initializeConversions()

isNarrowing

public static final boolean isNarrowing(int left,
                                        int right)
Predicate telling whether "left" can store a "right" using some narrowing conversion (is left smaller than right)

Parameters:
left - - the target type to convert to
right - - the actual type
Returns:
true if legal narrowing conversion

isWidening

public static final boolean isWidening(int left,
                                       int right)
Predicate telling whether "left" can store a "right" using some widening conversion (is left bigger than right)

Parameters:
left - - the target type to convert to
right - - the actual type
Returns:
true if legal widening conversion

computeUniqueKey

public char[] computeUniqueKey(boolean isLeaf)
int -> I

Overrides:
computeUniqueKey in class Binding

constantPoolName

public char[] constantPoolName()
Description copied from class: TypeBinding
Answer the receiver's constant pool name. NOTE: This method should only be used during/after code gen. e.g. 'java/lang/Object'

Specified by:
constantPoolName in class TypeBinding

getPackage

public PackageBinding getPackage()
Specified by:
getPackage in class TypeBinding

isCompatibleWith

T_null is acting as an unchecked exception

Overrides:
isUncheckedException in class TypeBinding
See Also:
TypeBinding.isUncheckedException(boolean)

kind

public int kind()
Overrides:
kind in class TypeBinding
See Also:
Binding.kind()

qualifiedSourceName

public char[] qualifiedSourceName()
Description copied from class: TypeBinding
Answer the source name for the type. In the case of member types, as the qualified name from its top level type. For example, for a member type N defined inside M & A: "A.M.N".

Specified by:
qualifiedSourceName in class TypeBinding

readableName

public char[] readableName()
Specified by:
readableName in class Binding

shortReadableName
