| Methods Summary |
|---|
| public static byte[] | readData(java.lang.String filename)This method reads hex data from a filename and returns a byte array.
The file may contain line comments that are preceeded with a # symbol.
File file = new File( filename );
FileInputStream stream = new FileInputStream( file );
try
{
return readData( stream, -1 );
}
finally
{
stream.close();
}
|
| public static byte[] | readData(java.lang.String filename, java.lang.String section)Same as readData(String) except that this method allows you to specify sections within
a file. Sections are referenced using section headers in the form:
[sectioname]
File file = new File( filename );
FileInputStream stream = new FileInputStream( file );
try
{
StringBuffer sectionText = new StringBuffer();
boolean inSection = false;
int c = stream.read();
while ( c != -1 )
{
switch ( c )
{
case '[":
inSection = true;
break;
case '\n":
case '\r":
inSection = false;
sectionText = new StringBuffer();
break;
case ']":
inSection = false;
if ( sectionText.toString().equals( section ) ) return readData( stream, '[" );
sectionText = new StringBuffer();
break;
default:
if ( inSection ) sectionText.append( (char) c );
}
c = stream.read();
}
}
finally
{
stream.close();
}
throw new IOException( "Section '" + section + "' not found" );

| public static byte[] | readData(java.io.InputStream stream, int eofChar)
int characterCount = 0;
byte b = (byte) 0;
List bytes = new ArrayList();
boolean done = false;
while ( !done )
{
int count = stream.read();
char baseChar = 'a";

switch ( count )
{

readToEOL( stream );
break;
case '0": case '1": case '2": case '3": case '4": case '5":
case '6": case '7": case '8": case '9":
b <<= 4;
b += (byte) ( count - '0" );
characterCount++;
if ( characterCount == 2 )
{
bytes.add( new Byte( b ) );
characterCount = 0;

}

}
Byte[] polished = (Byte[]) bytes.toArray( new Byte[0] );
byte[] rval = new byte[polished.length];
for ( int j = 0; j < polished.length; j++ )
{
rval[j] = polished[j].byteValue();
}
return rval;
|
| public static byte[] | readFromString(java.lang.String data)
return readData(new ByteArrayInputStream( data.getBytes() ), -1);
|
| private static void | readToEOL(java.io.InputStream stream)
int c = stream.read();
while ( c != -1 && c != '\n" && c != '\r" )
{
c = stream.read();
}
