Specified by:

configure in interface JVMComponent

Parameters:

jvm - the Java Virtual Machine

exec

public abstract void exec(JThread thread)
                   throws java.lang.Throwable

Executes this instruction in the specified thread.

Specified by:

exec in interface JInstruction

Parameters:

thread - a thread

Throws:

java.lang.Throwable - if an exception occurs during execution

getOpcode

public int getOpcode()

Returns the opcode of this instruction.

Specified by:

getOpcode in interface JInstruction

Returns:

the opcode of this instruction

getComponentClass

public abstract java.lang.Class getComponentClass()

Returns the class object describing this component.

Specified by:

getComponentClass in interface JVMComponent

toString

public abstract java.lang.String toString()

Returns a string representation of this instruction.

Overrides:

toString in class java.lang.Object

Returns:

a string representation of this instruction

replace

public void replace(JVMComponent component)

Replaces the data of this component by the data of the specified component. The type of component must be the type of this component. This method should be call when a component is replaced in the Corosol Virtual Machine.

Specified by:

replace in interface JVMComponent

Parameters:

component - a component to be used to initialize this component
