Enum Constant Detail

MEASURE_ALWAYS

public static final HasChildMeasurementHint.ChildMeasurementHint MEASURE_ALWAYS

Always measure all child components (default).

MEASURE_IF_NEEDED

public static final HasChildMeasurementHint.ChildMeasurementHint MEASURE_IF_NEEDED

Measure child component only if child component is a Layout or implements either ManagedLayout or ElementResizeListener.

MEASURE_NEVER

public static final HasChildMeasurementHint.ChildMeasurementHint MEASURE_NEVER

Never measure child components. This can improve rendering speed of components with lots of children (e.g. Table), but can cause some child components to be rendered incorrectly (e.g. ComboBox).

Method Detail

values

public static HasChildMeasurementHint.ChildMeasurementHint[] 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 (HasChildMeasurementHint.ChildMeasurementHint c : HasChildMeasurementHint.ChildMeasurementHint.values())
    System.out.println(c);

Returns:

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

valueOf

public static HasChildMeasurementHint.ChildMeasurementHint valueOf(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:

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

NullPointerException - if the argument is null
