Constructor Detail

Parser

public Parser(PdfDataObject contentStream)(Code)

Remarks

For internal use only.

Method Detail

getContentStream

public PdfDataObject getContentStream()(Code)

Gets the content stream on which parsing is done.

Remarks

A content stream may be made up of either a single stream or an array of streams.

getHex
protected static int getHex(int c)(Code)

getLength
public long getLength()(Code)

getPosition
public long getPosition()(Code)

getStream
public IInputStream getStream()(Code)
	Gets the current stream.

getStreamIndex
public int getStreamIndex()(Code)
	Gets the current stream index.

getToken
public Object getToken()(Code)
	Gets the currently-parsed token. The current token.

getTokenType
public TokenTypeEnum getTokenType()(Code)
	Gets the currently-parsed token type. The current token type.

isDelimiter
protected static boolean isDelimiter(int c)(Code)
	Evaluates whether a character is a delimiter [PDF:1.6:3.1.1].

isEOL
protected static boolean isEOL(int c)(Code)
	Evaluates whether a character is an EOL marker [PDF:1.6:3.1.1].

isWhitespace
protected static boolean isWhitespace(int c)(Code)
	Evaluates whether a character is a white-space [PDF:1.6:3.1.1].

moveNext
public boolean moveNext(int offset) throws FileFormatException(Code)
	Parameters: offset - Number of tokens to be skipped before reaching the intended one.

moveNext

public boolean moveNext() throws FileFormatException(Code)

Parse the next token [PDF:1.6:3.1].

Contract

Preconditions:
1. To properly parse the current token, the pointer MUST be just before its starting (leading whitespaces are ignored).
Postconditions:
1. When this method terminates, the pointer IS at the last byte of the current token.
Invariants:
1. The byte-level position of the pointer IS anytime (during token parsing) at the end of the current token (whereas the 'current token' represents the token-level position of the pointer).
Side-effects:
1. See Postconditions.

Whether a new token was found.

parseContentObject
public ContentObject parseContentObject() throws FileFormatException(Code)
	Parses the next content object [PDF:1.6:4.1], may it be a single operation or a graphics object. version: 0.0.4, 06/09/07 since: 0.0.4

parseContentObjects
public List<ContentObject> parseContentObjects() throws FileFormatException(Code)

parseOperation
public Operation parseOperation() throws FileFormatException(Code)

parsePdfObject

protected PdfDirectObject parsePdfObject() throws FileFormatException(Code)

Parse the current PDF object [PDF:1.6:3.2].

Contract

Preconditions:
1. When this method is invoked, the pointer MUST be at the first token of the requested object.
Postconditions:
1. When this method terminates, the pointer IS at the last token of the requested object.
Invariants:
1. (none).
Side-effects:
1. See Postconditions.

seek
public void seek(long position)(Code)

skip
public void skip(long offset)(Code)

skipWhitespace
public boolean skipWhitespace()(Code)
	Moves to the last whitespace after the current position in order to let read the first non-whitespace.
