Enum Constant Detail

JMX_BASED

public static final MemoryManager.Type JMX_BASED

Uses JMX memory management mbeans for tracking available memory.

SELF_MANAGED

public static final MemoryManager.Type SELF_MANAGED

Maintains memory usage itself. Different users can share this instance and indicate the increase/decrease in their memory usage by calling MemoryManager.changeMemoryUsedBy(long), and check if the total memory used by all users of this calls causes the available memory to become low using MemoryManager.isMemoryLow()

Method Detail

values

public static MemoryManager.Type[] 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 (MemoryManager.Type c : MemoryManager.Type.values())
    System.out.println(c);

Returns:

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

valueOf

public static MemoryManager.Type 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
