Method Detail

generalize

public Value generalize(Value other)

Description copied from class: Value

Returns the generalization of this Value and the given other Value.

Specified by:

generalize in class Value

isCategory2

public boolean isCategory2()

Description copied from class: Value

Returns whether the computational type of this Value is a category 2 type. This means that it takes up the space of two category 1 types on the stack, for instance.

Specified by:

isCategory2 in class Value

computationalType

public int computationalType()

Description copied from class: Value

Returns the computational type of this Value.

Specified by:

computationalType in class Value

Returns:

TYPE_INTEGER, TYPE_LONG, TYPE_FLOAT, TYPE_DOUBLE, TYPE_REFERENCE, or TYPE_INSTRUCTION_OFFSET.

internalType

public java.lang.String internalType()

Description copied from class: Value

Returns the internal type of this Value.

Specified by:

internalType in class Value

Returns:

TypeConstants.BOOLEAN, TypeConstants.BYTE, TypeConstants.CHAR, TypeConstants.SHORT, TypeConstants.INT , TypeConstants.LONG, TypeConstants.FLOAT, TypeConstants.DOUBLE, TypeConstants.CLASS_START ... TypeConstants.CLASS_END , or an array type containing any of these types (always as String).
