Method Details

asciiString

public static String asciiString(byte[] buf)

Convert to ASCII or return null if not compatible.

Parameters:

buf - the bytes representing a string

Returns:

the String represented by the bytes

asciiString

public static String asciiString(byte[] buf,
 int start,
 int len)

Convert to ASCII or return null if not compatible.

Parameters:

buf - buffer to get the string bytes from

start - the position where the string starts

len - the length of the string

Returns:

the extracted string

getBytes

public static byte[] getBytes(String in)

Convert an ASCII string to bytes.

Parameters:

in - the string to convert

Returns:

the string converted to bytes

isWhitespace

@Deprecated
public static boolean isWhitespace(char c)

Deprecated.

Use Character.isWhitespace(char) instead.

Parameters:

c - the character to check

Returns:

true if it is a white-space character, otherwise false.

parseInteger

public static int parseInteger(String s,
 ParsePosition pos)
                        throws IndexOutOfBoundsException,
NumberFormatException

Returns an integer value contained in a string the specified position. Leading spaces will be skipped and the parsing will stop at the first non-digit character after. *

Parameters:

s - A string

pos - the position in the string to parse an integer. The position is updated to point to after the white spaces and integer component (if any).

Returns:

the integer value parsed.

Throws:

NumberFormatException - if there is no integer value present at the position.

IndexOutOfBoundsException - if the parse position is outside of the string bounds

Since:

1.18

extractChar

public static char extractChar(String s,
 ParsePosition pos)
                        throws IndexOutOfBoundsException

Returns a character from a string, incrementing the position argument.

Parameters:

s - a string

pos - the position of the character to return. It is incremented.

Returns:

the character at the requested position

Throws:

IndexOutOfBoundsException - if the parse position is outside of the string bounds

Since:

1.18
