Method Detail

values

public static HotSpotMarkId[] values()

Returns:

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

valueOf

public static HotSpotMarkId valueOf(String name)

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

getValue

public int getValue()

getName

public String getName()

Description copied from interface: CompilationResult.MarkId

A human readable name for this mark.

Specified by:

getName in interface CompilationResult.MarkId

getId

public Object getId()

Description copied from interface: CompilationResult.MarkId

Return the object which should be used in the Mark. On some platforms that may be different than this object.

Specified by:

getId in interface CompilationResult.MarkId

isMarkAfter

public boolean isMarkAfter()

Description copied from interface: CompilationResult.MarkId

Indicates whether the mark is intended to identify the end of the last instruction or the beginning of the next instruction. This information is necessary if the backend needs to insert instructions after the normal assembly step.

Specified by:

isMarkAfter in interface CompilationResult.MarkId

isAvailable

public boolean isAvailable()

toString

public String toString()

Overrides:

toString in class Enum<HotSpotMarkId>
