Enum Constant Detail

INTERN_LEAF_NODES

public static final JsonParser.NodeInterningStrategy INTERN_LEAF_NODES

Use the same object for strings and numbers in a given document that are equal.

When the parser encounters a number node or a string node (including field names) equal to one it has previously encountered in the same document, it will use the same object for them, i.e. for any two strings or numbers a and b in a given document, if a.equals(b) then a == b.

This strategy trades a reduction in memory use for a small increase in computational cost.

INTERN_NOTHING

public static final JsonParser.NodeInterningStrategy INTERN_NOTHING

Use a new object for every string and number in a document.

For any two equivalent strings or numbers a and b in a given document, a.equals(b), but a != b.

This strategy minimises the computational cost of parsing at the expense of increased memory use.

Method Detail

values

public static JsonParser.NodeInterningStrategy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (JsonParser.NodeInterningStrategy c : JsonParser.NodeInterningStrategy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static JsonParser.NodeInterningStrategy valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
