Method Detail

add

public void add(java.lang.String property,
                JsonElement value)

Adds a member, which is a name-value pair, to self. The name must be a String, but the value can be an arbitrary JsonElement, thereby allowing you to build a full tree of JsonElements rooted at this node.

Parameters:

property - name of the member.

value - the member object.

remove

public JsonElement remove(java.lang.String property)

Removes the property from this JsonObject.

Parameters:

property - name of the member that should be removed.

Returns:

the JsonElement object that is being removed.

Since:

1.3

addProperty

public void addProperty(java.lang.String property,
                        java.lang.String value)

Convenience method to add a primitive member. The specified value is converted to a JsonPrimitive of String.

Parameters:

property - name of the member.

value - the string value associated with the member.

addProperty

public void addProperty(java.lang.String property,
                        java.lang.Number value)

Convenience method to add a primitive member. The specified value is converted to a JsonPrimitive of Number.

Parameters:

property - name of the member.

value - the number value associated with the member.

addProperty

public void addProperty(java.lang.String property,
                        java.lang.Boolean value)
