Constructor Detail

UnaryMinusExpr

public UnaryMinusExpr()
The noarg constructor is needed for ANTLR support and deserialization. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.


UnaryMinusExpr

public UnaryMinusExpr(antlr.Token token)
The noarg constructor is needed for ANTLR support. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.
