roo!™ Summary

roo!™ is an object-oriented enhancement of Kilowatt Software L.L.C.'s r4™ product. All programming capabilities in the r4™ product are also available in roo!™.

roo!™ provides the following object-oriented capabilities:

encapsulation abstraction derivation polymorphism

roo!™ provides the following additional built-in functions:

callback executes a C/C++ callback routine in the calling context changestr replaces occurrences of a string, with another string countstr counts occurrences of one string in another exists determines if a compound symbol value exists lower converts all, or part, of a string to lowercase nap takes a pause raiseObjection raises a program objection condition split splits a string into a vector of segments squareroot computes the square root of a numeric value

roo!™ provides compatibility with the following NetRexx capabilities:

[ ] array-like operators catch, finally condition handlers loop over aggregate objects, and compound stem groups

roo!™ provides the following built-in classes: Aggregate a generic collection base class BitVector a condensed vector of boolean values of a fixed size -- 4096 bits Callback abstract callback class associated with an external program CharacterVector a vector of one-byte wide characters Clipboard a clipboard text encapsulation Comparator abstract class for comparing two items Console console stream ContextVector (aka StackTrace) system call vector access class DriveContext (aka DiskContext) drive (disk) reference context Emitter an output stream emitter Exception exception information that can be referenced by catch condition handlers ExternalClass a class that is supported by an external program File file information FolderContext (aka DirectoryContext) folder (directory) reference context InLineFile an input file that is accessed as a sequence of lines InOutLineFile a file that is updated as a sequence of lines InStream default input stream (standard input) List a collection of heterogeneous items. Map a collection of heterogeneous items. a map is indexed by a string value Math various high precision (100 digit+) mathematic functions (natural logarithm, sine, cosine, etc) and constants (Π, e, Φ, γ) Object a generic object base class OrderedVector an ordered collection of items multiple items may have the same value OutLineFile an output file that is accessed as a sequence of lines OutStream default output stream (standard output) Pattern defines a regular expression text search pattern PatternMatch resulting information associated with a regular expression text search pattern Queue a collection of heterogeneous items, that is accessed at the front or end. Set an ordered collection of unique items Socket a TCP/IP socket send/receive class Stack a collection of heterogeneous items, that is accessed at the end. System system information SystemPropertyMap a collection of system properties (aka environment variables) a map is indexed by a string value Table a two dimensional table containing an arbitrary number of rows, and a fixed number of columns Tree a hierarchical object Vector a collection of heterogeneous items. WideCharacterVector a vector of two-byte wide characters
