Method Detail

getSize

public abstract int getSize()

Description copied from class: StackData

Specifies the size of this object on the operand stack.

Specified by:

getSize in class StackData

Returns:

the size of the object in bytes, 1 or 2.

getType

public abstract de.fub.bytecode.generic.Type getType()

Description copied from class: StackData

Specifies the type of the data.

Specified by:

getType in class StackData

Returns:

a type object which is the type (or a superclass of the type) for the data object

isComposite

public boolean isComposite()

hasDefinedValue

public boolean hasDefinedValue()

getValue

public java.lang.Number getValue()

equals

public boolean equals(java.lang.Object o)

Description copied from class: StackData

Tests for equality between any two data elements. Two StackData objects are equal iff they have the same instruction handle as their creation point. (subclasses have more restrictions for equality)

Overrides:

equals in class StackData

Parameters:

o - the object to test equality against

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
