INSTANCE

public static final ModelCache INSTANCE

Singleton instance.

Method Detail

values

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

Returns:

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

valueOf

public static ModelCache 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

getProcessModelIfCached

public com.whitestein.lsps.model.ProcessModel getProcessModelIfCached(long moduleId)

Returns the cached process model; returns null if the model is not stored in the cache.

Parameters:

moduleId -

Returns:

the cached process model or null

getProcessModelIfCached

public com.whitestein.lsps.model.ProcessModel getProcessModelIfCached(java.lang.String moduleHash)

Returns the cached process model; returns null if the model is not stored in the cache.

Parameters:

moduleHash -

Returns:

the cached process model or null

getElement
