Description

Interface Summary

Copy	Interface used to copy objects.
ErrorQueue	A ErrorQueue handles outputing error messages.
Predicate	Predicate Overview: This interface provides a general means for describing predicates about objects.
Transformation	Transformation Overview: This interface provides a general means for transforming objects.

Class Summary

AbstractErrorQueue	A StdErrorQueue handles outputing error messages.
Assert	Assert Overview: Assert contains a few methods helpful for implementing assertions in Java.
Base64	Encodes and decodes to and from Base64 notation.
Base64.InputStream	A Base64.InputStream will read data from another java.io.InputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
Base64.OutputStream	A Base64.OutputStream will write data to another java.io.OutputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
BitVector	A bit vector class implemented more naively than java.util.BitSet.
CachingTransformingList	This subclass of TransformingList applies the transformation to each element of the underlying list at most once.
CodeWriter	A CodeWriter is a pretty-printing engine.
CollectionUtil	Collection utilities.
ConcatenatedIterator	ConcatenatedIterator Overview: This iterator wraps other iterators, and returns all their elements in order.
Enum	An enumerated type.
ErrorInfo	Information about an error message.
FilteringIterator	FilteringIterator Overview: This iterator wraps another iterator, and returns only those elements for which a given predicate is true.
IdentityKey	Class to be used for inserting objects in hashtables using pointer equality.
NestedMap	A NestedMap is a map which, when it cannot find an element in itself, defers to another map.
NilMap	This class represents a constant map which never contains any elements.
Pair	A two-element tuple.
Position	This class represents a posiiton within a file.
SilentErrorQueue	A SilentErrorQueue records but does not output error messages.
StdErrorQueue	A StdErrorQueue handles outputing error messages.
StringUtil	String utilities.
SubtypeSet	Class to implement sets containing polyglot.types.Type .
TransformingIterator	TransformingIterator Overview: This is a swiss-army-knife of iterators.
TransformingList	This unmodifiable List supports performing an arbitrary transformation on the underlying list's elements.
TypedList	A TypedList is an List which will not allow members not belonging to a given type to be added to a collection.
TypedListIterator	A TypedListIterator is an ListIterator which will not allow members not belonging to a given type to be added to a collection.
TypeEncoder	The TypeEncoder gives the ability to encode a polyglot Type as a Java string.
TypeInputStream	Input stream for reading type objects.
TypeOutputStream	Output stream for writing type objects.
UnicodeWriter	Output stream for writing unicode.
UniqueID	A unique identifier generator.
WorkList	This class represents a set of calculations to be performed, some of which have already been completed.

Exception Summary

ErrorLimitError	Exception thrown when the number of errors exceeds a limit.
InternalCompilerError	Exception thrown when the compiler is confused.
