Member Function Documentation
| void org.pdfclown.util.parsers.PostScriptParser.Dispose | ( | ) | [inherited] |
| override int org.pdfclown.util.parsers.PostScriptParser.GetHashCode | ( | ) | [inherited] |
References org.pdfclown.bytes.IInputStream.GetHashCode().
| object org.pdfclown.util.parsers.PostScriptParser.GetToken | ( | int | offset | ) | [inherited] |
Gets a token after moving to the given offset.
- Parameters:
-
offset Number of tokens to skip before reaching the intended one.
- See also:
- Token
| bool org.pdfclown.util.parsers.PostScriptParser.MoveNext | ( | int | offset | ) | [inherited] |
Moves the pointer to the next token.
- Parameters:
-
offset Number of tokens to skip before reaching the intended one.
| override bool org.pdfclown.tokens.FileParser.MoveNext | ( | ) | [virtual] |
Moves the pointer to the next token.
To properly parse the current token, the pointer MUST be just before its starting (leading whitespaces are ignored). When this method terminates, the pointer IS at the last byte of the current token.
- Returns:
- Whether a new token was found.
Reimplemented from org.pdfclown.tokens.BaseParser.
References org.pdfclown.bytes.IInputStream.Position, and org.pdfclown.bytes.IInputStream.Seek().
| PdfDataObject org.pdfclown.tokens.BaseParser.ParsePdfObject | ( | int | offset | ) | [inherited] |
Parses a PDF object after moving to the given token offset.
- Parameters:
-
offset Number of tokens to skip before reaching the intended one.
- See also:
- ParsePdfObject()
| override PdfDataObject org.pdfclown.tokens.FileParser.ParsePdfObject | ( | ) | [virtual] |
Parses the current PDF object [PDF:1.6:3.2].

| string org.pdfclown.tokens.FileParser.RetrieveVersion | ( | ) |
Retrieves the PDF version of the file [PDF:1.6:3.4.1].
References org.pdfclown.bytes.IInputStream.Position, org.pdfclown.bytes.IInputStream.ReadString(), and org.pdfclown.bytes.IInputStream.Seek().
| long org.pdfclown.tokens.FileParser.RetrieveXRefOffset | ( | ) |

| void org.pdfclown.util.parsers.PostScriptParser.Seek | ( | long | offset | ) | [inherited] |
Moves the pointer to the given absolute byte position.
| void org.pdfclown.util.parsers.PostScriptParser.Skip | ( | long | offset | ) | [inherited] |
Moves the pointer to the given relative byte position.
| bool org.pdfclown.util.parsers.PostScriptParser.SkipEOL | ( | ) | [inherited] |
Moves the pointer before the next non-EOL character after the current position.
- Returns:
- Whether the stream can be further read.
| bool org.pdfclown.util.parsers.PostScriptParser.SkipWhitespace | ( | ) | [inherited] |
Moves the pointer before the next non-whitespace character after the current position.
- Returns:
- Whether the stream can be further read.
