Generates new T[size].

Parameters:

type - The type of the array component. 'T' or new T[size].

 int size)

Generates new T[size].

Parameters:

type - The type of the array component. 'T' or new T[size].

_this

public static JExpression _this()

Returns a reference to "this", an implicit reference to the current object.

_super

public static JExpression _super()

Returns a reference to "super", an implicit reference to the super class.

_null

lit

public static JExpression lit(long n)

lit

public static JExpression lit(float f)

lit

public static JExpression lit(double d)

quotify

public static String quotify(char quote,
 String s)

lit

public static JExpression lit(char c)

lit

public static JExpression lit(String s)

direct

public static JExpression direct(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.
