Member Function Documentation

void org.pdfclown.util.parsers.PostScriptParser.Dispose

(

)

override int org.pdfclown.util.parsers.PostScriptParser.GetHashCode

(

)

References org.pdfclown.bytes.IInputStream.GetHashCode().

object org.pdfclown.util.parsers.PostScriptParser.GetToken

(

int

offset

)

Gets a token after moving to the given offset.

Parameters:

offset

Number of tokens to skip before reaching the intended one.

See also:

Token

virtual bool org.pdfclown.util.parsers.PostScriptParser.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 in org.pdfclown.tokens.BaseParser, and org.pdfclown.tokens.FileParser.

bool org.pdfclown.util.parsers.PostScriptParser.MoveNext

(

int

offset

)

Moves the pointer to the next token.

Parameters:

offset

Number of tokens to skip before reaching the intended one.

void org.pdfclown.util.parsers.PostScriptParser.Seek

(

long

offset

)

Moves the pointer to the given absolute byte position.

void org.pdfclown.util.parsers.PostScriptParser.Skip

(

long

offset

)

Moves the pointer to the given relative byte position.

bool org.pdfclown.util.parsers.PostScriptParser.SkipEOL

(

)

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

(

)

Moves the pointer before the next non-whitespace character after the current position.

Returns:

Whether the stream can be further read.
