jminusminus.JStringConcatenationOp

class JStringConcatenationOp
extends JBinaryExpression

The AST node for a string concatenation operation. Nodes of this type are not produced by the parser, but by analysis of a + operation where the arguments are strings. Such operations are rewritten to be string concatenation operations.
