Method Detail

atEnd

public final boolean atEnd()

---

getCurrentIdentifierSource

public char[] getCurrentIdentifierSource()

---

getCurrentTokenEndPosition

public int getCurrentTokenEndPosition()

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Answers the ending position of the current token inside the original source. This position is zero-based and inclusive. It corresponds to the position of the last character which is part of this token. If this character was a unicode escape sequence, it points at the last character of this sequence.

Specified by:

getCurrentTokenEndPosition in interface org.eclipse.jdt.core.compiler.IScanner

---

getCurrentTokenSource

public final char[] getCurrentTokenSource()

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Answers the current identifier source, after unicode escape sequences have been translated into unicode characters. For example, if original source was \\u0061bc then it will answer abc.

Specified by:

getCurrentTokenSource in interface org.eclipse.jdt.core.compiler.IScanner

---

getCurrentTokenSourceString

public final char[] getCurrentTokenSourceString()

---

getCurrentTokenStartPosition

public int getCurrentTokenStartPosition()

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Answers the starting position of the current token inside the original source. This position is zero-based and inclusive. It corresponds to the position of the first character which is part of this token. If this character was a unicode escape sequence, it points at the first character of this sequence.

Specified by:

getCurrentTokenStartPosition in interface org.eclipse.jdt.core.compiler.IScanner

---

getLineEnd

public final int getLineEnd(int lineNumber)

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Answers the ending position of a given line number. This line has to have been encountered already in the tokenization process (in other words, it cannot be used to compute positions of lines beyond current token). Once the entire source has been processed, it can be used without any limit. Line ending positions are zero-based, and correspond to the last character of the line separator (in case multi-character line separators).

Specified by:

getLineEnd in interface org.eclipse.jdt.core.compiler.IScanner

---

getLineStart

public final int getLineStart(int lineNumber)

Search the source position corresponding to the beginning of a given line number Line numbers are 1-based, and relative to the scanner initialPosition. Character positions are 0-based. e.g. getLineStart(1) --> 0 i.e. first line starts at character 0. In case the given line number is inconsistent, answers -1.

Specified by:

getLineStart in interface org.eclipse.jdt.core.compiler.IScanner

---

                 throws org.eclipse.jdt.core.compiler.InvalidInputException

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Read the next token in the source, and answers its ID as specified by ITerminalSymbols. Note that the actual token ID values are subject to change if new keywords were added to the language (for instance, 'assert' is a keyword in 1.4).

Specified by:

getNextToken in interface org.eclipse.jdt.core.compiler.IScanner

---

getNextUnicodeChar

public final void getNextUnicodeChar()
                              throws java.lang.IndexOutOfBoundsException,
                                     org.eclipse.jdt.core.compiler.InvalidInputException

                                        throws org.eclipse.jdt.core.compiler.InvalidInputException

---

getLineEnds

public final int[] getLineEnds()

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Answers an array of the ending positions of the lines encountered so far. Line ending positions are zero-based, and correspond to the last character of the line separator (in case multi-character line separators).

Specified by:

getLineEnds in interface org.eclipse.jdt.core.compiler.IScanner

---

getSource

public char[] getSource()

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Answers the original source being processed (not a copy of it).

Specified by:

---

recordComment

public final void recordComment(boolean isJavadoc)

---

resetTo

public void resetTo(int begin,
                    int end)

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Reposition the scanner on some portion of the original source. The given endPosition is the last valid position. Beyond this position, the scanner will answer EOF tokens (ITerminalSymbols.TokenNameEOF).

Specified by:

resetTo in interface org.eclipse.jdt.core.compiler.IScanner

---

scanEscapeCharacter

public final void scanEscapeCharacter()
                               throws org.eclipse.jdt.core.compiler.InvalidInputException

---

scanIdentifierOrKeyword

public int scanIdentifierOrKeyword()
                            throws org.eclipse.jdt.core.compiler.InvalidInputException

getLineNumber

public final int getLineNumber(int position)

Search the line number corresponding to a specific position

Specified by:

getLineNumber in interface org.eclipse.jdt.core.compiler.IScanner

---

setSource

public final void setSource(char[] source)

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Set the scanner source to process. By default, the scanner will consider starting at the beginning of the source until it reaches its end.

Specified by:

setSource in interface org.eclipse.jdt.core.compiler.IScanner

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

toStringAction

public final java.lang.String toStringAction(int act)

---

checkNonExternalizeString

private void checkNonExternalizeString()
                                throws org.eclipse.jdt.core.compiler.InvalidInputException

---

parseTags

private void parseTags(org.eclipse.jdt.internal.compiler.parser.NLSLine line)

public char[] getRawTokenSource()

Description copied from interface: org.eclipse.jdt.core.compiler.IScanner

Answers the current identifier source, before unicode escape sequences have been translated into unicode characters. For example, if original source was \\u0061bc then it will answer \\u0061bc.

Specified by:

getRawTokenSource in interface org.eclipse.jdt.core.compiler.IScanner
