Method Detail

setQuoteChars

public void setQuoteChars(char[] chars)

getQuoteChars

public char[] getQuoteChars()

setEscapeChars

public void setEscapeChars(char[] chars)

getEscapeChars

public char[] getEscapeChars()

delimit

public ArgumentCompleter.ArgumentList delimit(java.lang.CharSequence buffer,
                                              int cursor)

Description copied from interface: ArgumentCompleter.ArgumentDelimiter

Break the specified buffer into individual tokens that can be completed on their own.

Specified by:

delimit in interface ArgumentCompleter.ArgumentDelimiter

Parameters:

buffer - The buffer to split

cursor - The current position of the cursor in the buffer

Returns:

The tokens

isDelimiter

public boolean isDelimiter(java.lang.CharSequence buffer,
                           int pos)

Returns true if the specified character is a whitespace parameter. Check to ensure that the character is not escaped by any of getQuoteChars(), and is not escaped by ant of the getEscapeChars(), and returns true from isDelimiterChar(java.lang.CharSequence, int).

Specified by:

isDelimiter in interface ArgumentCompleter.ArgumentDelimiter

Parameters:

buffer - The complete command buffer

pos - The index of the character in the buffer

Returns:

True if the character should be a delimiter

isQuoted

public boolean isQuoted(java.lang.CharSequence buffer,
                        int pos)

isQuoteChar

public boolean isQuoteChar(java.lang.CharSequence buffer,
                           int pos)

isEscapeChar

public boolean isEscapeChar(java.lang.CharSequence buffer,
                            int pos)

Check if this character is a valid escape char (i.e. one that has not been escaped)

isEscaped

public boolean isEscaped(java.lang.CharSequence buffer,
                         int pos)

Check if a character is escaped (i.e. if the previous character is an escape)

Parameters:

buffer - the buffer to check in

pos - the position of the character to check

Returns:

true if the character at the specified position in the given buffer is an escape character and the character immediately preceding it is not an escape character.

isDelimiterChar

public abstract boolean isDelimiterChar(java.lang.CharSequence buffer,
                                        int pos)

Returns true if the character at the specified position if a delimiter. This method will only be called if the character is not enclosed in any of the getQuoteChars(), and is not escaped by ant of the getEscapeChars(). To perform escaping manually, override isDelimiter(java.lang.CharSequence, int) instead.
