Method Detail

isInteger

public static boolean isInteger(java.lang.String string)

Determines whether or not the provided string represents an integer value (for example, it will return true for values like "0", "1", "-7", "42", but false for strings like "7.62", "Hello", "5+5" etc).

Parameters:

string - the string you want to check.

Returns:

true if the provided string represents an int value, false if not.

isNumeric

public static boolean isNumeric(java.lang.String string)

Determines whether or not the provided string represents a numeric value (integer or float, for example, it will return true for values like "0", "1.426", "-100", "22.0", but false for strings like "3k", "Bonjour", "7*7" etc).

Parameters:

string - the string you want to check.

Returns:

true if the provided string represents a numeric value, false if not.

isHex

public static boolean isHex(java.lang.String string)

Determines whether or not the provided string represents a hexadecimal (hex) value using a "0x" prefix (for example, it will return true for values like "0xFF", "0xaabbcc", "0x41AB", "0x0", but false for strings like "56", "#FFAA13", "0xZVKK").

Parameters:

string - the string you want to check.

Returns:

true if the provided string represents a hex value, false if not.

isBoolean

public static boolean isBoolean(java.lang.String string)

Determines whether or not the provided string represents a boolean value (lower case, it will only return true for "true" or "false").

Parameters:

string - the string you want to check.

Returns:

true if the provided string equals "true" or "false", false if not.

removeAllNonWordCharacters

public static java.lang.String removeAllNonWordCharacters(java.lang.String string)

removeAllWhitespaces

public static java.lang.String removeAllWhitespaces(java.lang.String string)

removeAllLeadingWhitespaces

public static java.lang.String removeAllLeadingWhitespaces(java.lang.String string)

Removes all leading white spaces. E.g. if you provide the string " Test", this function returns "Test". If you provide "Hello World", this function returns the unmodified "Hello World" string.

Parameters:

string - the string you want to remove the leading white spaces from.

Returns:

the new string which does not contain any leading white spaces.

removeAllTrailingWhitespaces

public static java.lang.String removeAllTrailingWhitespaces(java.lang.String string)

getLines

public static java.lang.String[] getLines(java.lang.String string)

Splits the string by new line characters, i.e. \n or \r etc. Returns a character containing the individual lines. Does not contain empty lines.

Parameters:

string - the string you want to split, e.g. the text from a text file.

Returns:

the individual lines as an array of strings.

getMd5

public static java.lang.String getMd5(java.lang.String string)

Generates an MD5 hash from the provided string. This is useful for checksums etc., but keep in mind that MD5 is not safe enough for saving passwords, for example.

Parameters:

string - the string you want to turn into an MD5 hash.

Returns:

an MD5 hash.

vector3fToString

public static java.lang.String vector3fToString(Vector3f vector3f)
