String

Operations

size(): Integer

Returns the length of s.

concat(s: String): String

Returns the concatenation of self and s.
SQL template: self | s

+(a: OclAny): String [I]

Returns the concatenation of self and o. Equivalent to self.concat(o.toString())
Syntax: self + a; SQL template: self | a

toUpper(): String [I]

Returns a copy of self with all characters converted to upper case.
SQL template: upper(self)

toLower(): String [I]

Returns a copy of self with all characters converted to lower case.
SQL template: lower(self)

substring(i1: Integer, i2: Integer): String

Returns the substring of self, starting at the index position i1, ranging to and including i2. Please note that the index of the first character of a string is 1.

substring(i: Integer): String [I]

Returns the substring of self, starting at the index position i. Please note that the index of the first character of a string is 1.

pos(s: String): Integer [I]

Deperecated. Returns the first index position of s in self. If s1 cannot be found in s, 0 is retuned.
SQL template: position(s in self)

indexOf(s: String): Integer [I]

Returns the first index position of s in self. If s1 cannot be found in s, OclUndefined is retuned.
SQL template: position(s in self)

toInteger(): Integer

Converts self to an integer value.

toInteger(s: String): Integer [I]

Converts self to an integer value, assuming that s is formatted according to s.

toReal(): Real

Converts self to a real value.

toReal(s: String): Real [I]

Converts self to a real value, assuming that self is formatted according to s.

toDateTime(): DateTime [I]

Converts self from the ISO time format to a DateTime value.

toDateTime(s: String): DateTime [I]

Converts self to a DateTime value that is formatted with respect to s to a DateTime value.

startsWith(s: String): Boolean [I]

Returns true if self begins with s.
SQL template: position(s in self) = 1

endsWith(s: String): Boolean [I]

True if self ends with s.

replace(s1: String, s2: String): String [I]

Replaces all occurences of s1 in self by s2.

toAscii(): String

Converts self to a string that contains only ASCII characters (Unicodes 32-127). Unsupported characters are replaced by a question mark.

at(i: Integer): Integer

Returns the Unicode value of the i-th character of self.
