@Nonnull
public static String quotify(char quote,

                     String s)

Escapes the given string, then surrounds it by the specified quotation mark.

s - Source string to quote

Returns:

Qutoed string

@Nonnull
public static JAtom lit(char c)

direct

@Nonnull
public static AbstractJExpressionImpl direct(@Nonnull
                                     String source)

Creates an expression directly from a source code fragment.

This method can be used as a short-cut to create a JExpression. For example, instead of _a.gt(_b), you can write it as: JExpr.direct("a>b").

Be warned that there is a danger in using this method, as it obfuscates the object model.

Parameters:

source - Java source code

Returns:

Direct expression

cond

@Nonnull
public static JOpTernary cond(@Nonnull
                      IJExpression cond,
                      @Nonnull
                      IJExpression ifTrue,
                      @Nonnull
                      IJExpression ifFalse)

Just a sanity wrapper around JOp.cond(IJExpression, IJExpression, IJExpression) for easier finding.

Parameters:

cond - Condition

ifTrue - True condition

ifFalse - False condition

Returns:

The created expression
