public void startString()
                 throws java.io.IOException

Writes the '<' character that starts a string.

Throws:

java.io.IOException

write

public void write(java.lang.String cmd)
           throws java.io.IOException

Writes the given string to the output.

Parameters:

cmd - a string

Throws:

java.io.IOException

writeln

public void writeln(java.lang.String cmd)
             throws java.io.IOException

Writes the given string to the output, followed by a newline.

Parameters:

cmd - a string

Throws:

java.io.IOException

streamBytes

public void streamBytes(byte[] byteArray,
                        int offset,
                        int length)
                 throws java.io.IOException

Writes bytes from the given byte array to the output.

Parameters:

byteArray - byte[] a byte array

offset - the position in the byte array where the streaming must start

length - the number of bytes to stream. This MUST be less than MAX_BUFFER_SIZE - 1 since strings are suffixed by '00' (see Section 4.2 of Adobe Technical Note #5012, The Type 42 Font Format Specification.).

Throws:

java.io.IOException
