	`public String`	`errorDetails(String message)` Builds an error message using the current reader context.
	`public char[]`	`findNextChar(int match, int esc)` Collects characters until the next unescaped match character.
	`public boolean`	`hadEscape()` Reports whether the last string scan encountered an escape sequence.
	`public final boolean`	`hasChar()` Checks whether another character is available.
	`public final int`	`location()` Returns the current buffer index for diagnostics.
	`public final int`	`nextChar()` Advances to the next character.
	`public char[]`	`readNumber()` Reads a numeric token from the current position.
	`public final int`	`safeNextChar()` Advances when possible and returns `-1` at end of input.

    Creates a buffered character source.
    Parameters:
    reader - reader supplying characters
    readAheadSize - number of characters to read per buffer refill
  - public ReaderCharacterSource(Reader reader)
    
    Creates a buffered character source with the default read-ahead size.
    Parameters:
    reader - reader supplying characters
  - public ReaderCharacterSource(String string)
    
    Creates a character source over an in-memory string.
    Parameters:
    string - JSON content to expose as characters
- Method Detail
  - public final boolean consumeIfMatch(char[] match)
    
    Consumes the supplied character sequence when it matches the current position.
    Parameters:
    match - character sequence to test
    Returns:
    true when the sequence was consumed
  - public final int currentChar()
    
    Returns the current character without advancing.
    Returns:
    current character code
  - public String errorDetails(String message)
    
    Builds an error message using the current reader context.
    Parameters:
    message - parser-specific message
    Returns:
    formatted error details
  - public char[] findNextChar(int match, int esc)
    
    Collects characters until the next unescaped match character.
    Parameters:
    match - terminating character to search for
    esc - escape character that shields the following character
    Returns:
    collected characters between the current position and the terminator
  - public boolean hadEscape()
    
    Reports whether the last string scan encountered an escape sequence.
    Returns:
    true when an escape was seen
  - public final boolean hasChar()
    
    Checks whether another character is available.
    Returns:
    true when more input remains
  - public final int location()
    
    Returns the current buffer index for diagnostics.
    Returns:
    current character index
  - public final int nextChar()
    
    Advances to the next character.
    Returns:
    next character code
  - public char[] readNumber()
    
    Reads a numeric token from the current position.
    Returns:
    characters that form the numeric token
  - public final int safeNextChar()
    
    Advances when possible and returns -1 at end of input.
    Returns:
    next character code or -1 when no more input remains
