Method Detail

parseForObject

@JsOverlay
public static NativeObject parseForObject(String text)

Parses a JSON string, constructing the JavaScript value or object described by the string.

Parameters:

text - the string to parse as JSON.

Returns:

the object corresponding to the given JSON text.

parseForArray

@JsOverlay
public static <T extends Array> T parseForArray(String text)

Parses a JSON string, constructing the JavaScript array described by the string.

Type Parameters:

T - type of native array

Parameters:

text - the string to parse as JSON.

Returns:

the array corresponding to the given JSON text.

stringify

@JsOverlay
public static String stringify(Object obj)

Converts a JavaScript object or value to a JSON string. By default, the space value is set to -1 that no space should be used.

Parameters:

obj - The value to convert to a JSON string.

Returns:

A JSON string representing the given value.

stringify

@JsOverlay
public static String stringify(Object obj,
                               int spaces)

Converts a JavaScript object or value to a JSON string.

Parameters:

obj - The value to convert to a JSON string.

spaces - it indicates the number of space characters to use as white space; this number is capped at 10 (if it is greater, the value is just 10). Values less than 1 indicate that no space should be used.

Returns:

A JSON string representing the given value.

stringifyWithReplacer

@JsOverlay
public static String stringifyWithReplacer(Object obj)

Converts a JavaScript object or value to a JSON string, the space value is set to -1 that no space should be used and uses a default replacer to avoid TypeError: cyclic object value.

Parameters:

obj - The value to convert to a JSON string.

Returns:

A JSON string representing the given value.

stringifyWithReplacer

@JsOverlay
public static String stringifyWithReplacer(Object obj,
                                           int spaces)

Converts a JavaScript object or value to a JSON string, using a default replacer to avoid TypeError: cyclic object value.

Parameters:

obj - The value to convert to a JSON string.

spaces - it indicates the number of space characters to use as white space; this number is capped at 10 (if it is greater, the value is just 10). Values less than 1 indicate that no space should be used.

Returns:

A JSON string representing the given value.

stringifyWithReplacer

@JsOverlay
public static String stringifyWithReplacer(Object obj,
                                           JSON.Replacer replacer,
                                           int spaces)

Converts a JavaScript object or value to a JSON string.

Parameters:

obj - The value to convert to a JSON string.

replacer - A function that alters the behavior of the stringification process.

spaces - it indicates the number of space characters to use as white space; this number is capped at 10 (if it is greater, the value is just 10). Values less than 1 indicate that no space should be used.

Returns:

A JSON string representing the given value.
