instructionOffsetValue

public final InstructionOffsetValue instructionOffsetValue()

Description copied from class: Value

Returns this Value as a InstructionOffsetValue.

Overrides:

instructionOffsetValue in class Value

generalize

public final 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

computationalType

public final int computationalType()

Description copied from class: Value

Returns the computational type of this Value. The type is one of

• TYPE_INTEGER
• TYPE_LONG
• TYPE_FLOAT
• TYPE_DOUBLE
• TYPE_REFERENCE
• TYPE_INSTRUCTION_OFFSET

Specified by:

computationalType in class Value

category1Value

public final proguard.optimize.evaluation.value.Category1Value category1Value()

Description copied from class: Value

Returns this Value as a Category1Value.

Overrides:

category1Value in class Value

isCategory2

public final 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.
