> Hello,
> Im trying to convert an existing grammar written for C target into one for Java.
> In the C grammar there exists an init section which I figured
> converted the input stream into lowercase, as:
> @init {
>  ANTLR_UINT32 (*oldLA) ( struct ANTLR3_INT_STREAM_struct *, ANTLR_INT32 );
> oldLA = INPUT-> istream->_LA;
> INPUT->setUcaseLA(INPUT, ANTLR3_FALSE);
> }
> Is there any equivalent way of doing this for the Java target?
> Any help would be appreciated.
