The classes necessary to create and represent a Java method as an
expression tree. The nodes of the tree model various operations
(arithmetic operations, method calls, exceptions being thrown, etc.)
performed by a method. There are also classes that let you visit and
operate on the tree.

depending on whether or not the expression evaluated to zero. |

opposed to a local variable or a variable on the stack. |

handler. |

graph during conversion of variables to static single-assignment form. |
| PhiStmt.java | Class | A PhiStmt is inserted into a CFG in Single Static Assignment for. |

Node to a stream. |
