protected AbstractValue(LIRKind lirKind)

Initializes a new value of the specified kind.

Parameters:

lirKind - the kind

Method Detail

getKindSuffix

protected final String getKindSuffix()

Returns a String representation of the kind, which should be the end of all Object.toString() implementation of subclasses.

getKind

public final Kind getKind()

Returns the kind of this value.

Specified by:

getKind in interface KindProvider

getLIRKind

public final LIRKind getLIRKind()

Specified by:

getLIRKind in interface Value

getPlatformKind

public final PlatformKind getPlatformKind()

Returns the platform specific kind used to store this value.

Specified by:

getPlatformKind in interface Value

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

identityEquals

public final boolean identityEquals(AbstractValue other)

Checks if this value is identical to other. Warning: Use with caution! Usually equivalence equals(Object) is sufficient and should be used.
