Method Detail

values

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

Returns:

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

valueOf

public static TimelineEntityType 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

isParent

public boolean isParent(TimelineEntityType type)

Whether the input type can be a parent of this entity.

Parameters:

type - entity type.

Returns:

true, if this entity type is parent of passed entity type, false otherwise.

isChild

public boolean isChild(TimelineEntityType type)

Whether the input type can be a child of this entity.

Parameters:

type - entity type.

Returns:

true, if this entity type is child of passed entity type, false otherwise.

matches

public boolean matches(java.lang.String typeString)

Whether the type of this entity matches the type indicated by the input argument.

Parameters:

typeString - entity type represented as a string.

Returns:

true, if string representation of this entity type matches the entity type passed.
