Method Detail

concatJsExprs

public static JsExpr concatJsExprs(List<? extends JsExpr> jsExprs)

Builds one JS expression that computes the concatenation of the given JS expressions. The '+' operator is used for concatenation. Operands will be protected with an extra pair of parentheses if and only if needed.

The resulting expression is not guaranteed to be a string if the operands do not produce strings when combined with the plus operator; e.g. 2+2 might be 4 instead of '22'.

Parameters:

jsExprs - The JS expressions to concatentate.

Returns:

One JS expression that computes the concatenation of the given JS expressions.

isStringLiteral

public static boolean isStringLiteral(JsExpr jsExpr)

toString

public static JsExpr toString(JsExpr expr)
