Field Details

notZero

public static final Function<Jsons.Val,Boolean> notZero

Check if a value is not ZERO_VAL.

getVal

public static final Function<Jsons.Prop,Jsons.Val> getVal

Get the value from a property.

NULL

public static final Jsons.Val NULL

JSON null.

ZERO_VAL

public static final Jsons.Val ZERO_VAL

Identity for values.

ZERO_OBJ

public static final Jsons.Obj ZERO_OBJ

Identity for objects.

ZERO_ARR

public static final Jsons.Arr ZERO_ARR

Identity for arrays.

stringVal

public static final Function<String,Jsons.Val> stringVal

Method Details

toJson

public static String toJson(Jsons.Obj obj)

toJson

public static String toJson(Jsons.Arr arr)

obj

public static Jsons.Obj obj(Jsons.Prop... ps)

Create an object.

arr

public static Jsons.Arr arr(Jsons.Val... vs)

Create an array.

arr

public static Jsons.Arr arr(List<Jsons.Val> vs)

Create an array.

arr

public static Jsons.Arr arr(Monadics.ListMonadic<Jsons.Val> vs)

Create an array.

v

public static Jsons.Val v(Number v)

v

public static Jsons.Val v(String v)

v

public static Jsons.Val v(Boolean v)

v

public static Jsons.Val v(Date v)

p

public static Jsons.Prop p(String key,
 Jsons.Val val)

Create a property.

p

public static Jsons.Prop p(String key,
 Option<Jsons.Val> val)

Create a property. Passing none is like setting ZERO_VAL which erases the property.

p

public static Jsons.Prop p(String key,
 Number value)

Create a property. Convenience.

p

public static Jsons.Prop p(String key,
 String value)

Create a property. Convenience.

p

public static Jsons.Prop p(String key,
 Boolean value)

Create a property. Convenience.

append

public static Jsons.Obj append(Jsons.Obj... os)

Merge a list of objects into one (last one wins).

append

public static Jsons.Arr append(Jsons.Arr... as)

Append a list of arrays into one.
