Constructor Detail

PSElement

public PSElement(java.lang.String operator,
                 int startPoint)

Method Detail

getOperator

public java.lang.String getOperator()

Gets the Postscript element operator

Returns:

The operator returned as a string

getStartPoint

public int getStartPoint()

The start location of the element within the source binary data

Returns:

The start location returned as an integer

getEndPoint

public int getEndPoint()

The end location of the element within the source binary data

Returns:

The end location returned as an integer

parse

public void parse(byte cur,
                  int pos)
           throws java.io.UnsupportedEncodingException

Takes over the task of tokenizing the byte data

Parameters:

cur - The current byte being read

Throws:

java.io.UnsupportedEncodingException

parseByte

public abstract void parseByte(byte cur,
                               int pos)

Passes responsibility for processing the byte stream to the PostScript object

Parameters:

cur - The byte currently being read

pos - The position of the given byte

parseToken

public abstract void parseToken(java.lang.String token,
                                int curPos)

Delegates the parse routine to a sub class

Parameters:

token - The token which to parse

isInteger

protected boolean isInteger(java.lang.String intValue)

getBinaryEntries

public java.util.LinkedHashMap<java.lang.String,int[]> getBinaryEntries()

getBinaryEntryByIndex

public int[] getBinaryEntryByIndex(int index)

Gets the binary entry location of a given index from the array

Parameters:

index - The index for which to retrieve the binary data location

Returns:

hasMore

public boolean hasMore()

Determines if more data is still to be parsed for the Postscript element.

Returns:

Returns true if more data exists

setFoundUnexpected

protected void setFoundUnexpected(boolean foundUnexpected)

Sets a value to be true if an expected entry postscript is found in the element. An example is where the encoding table may have a series of postscript operators altering the state of the array. In this case the only option will be to fully embed the font to avoid incorrect encoding in the resulting subset.

Parameters:

foundUnexpected - true if unexpected postscript is found.

getFoundUnexpected

public boolean getFoundUnexpected()

Returns whether unexpected postscript has been found in the element

Returns:

true if unexpected postscript is found
