compileAdditiveExpression

protected void compileAdditiveExpression()

compileMultiplicativeExpression

protected void compileMultiplicativeExpression()

compileUnaryExpression

protected void compileUnaryExpression()

compileUnaryExpressionNotPlusMinus

protected void compileUnaryExpressionNotPlusMinus()

compilePrimary

protected void compilePrimary()

this compiles a primary. First look for a literal (e.g. "text"), then an identifier(e.g. variable) In the next step, call a function, if executing a function, on the literal or the identifier found.

compileLiteral

protected boolean compileLiteral()

A literal is one value of any type. Supported literals are of types String, Floating Point, Integer, Character, Boolean and null e.g. 'J', "String", 1, 1.8, true, false, null.

Returns:

The compiled literal
