Constructor Detail

Double

public Double()

Default constructor

Double

public Double(Double input)

Copy constructor

Parameters:

input - instance to copy

Method Detail

fromPointer

public static Double fromPointer(long cptr)

Creates a java object instance from a C/C++ pointer

Parameters:

cptr - C pointer to the object

Returns:

a new java instance of the underlying pointer

fromPointer

public static Double fromPointer(long cptr,
                                 boolean shouldManage)

Creates a java object instance from a C/C++ pointer

Parameters:

cptr - C pointer to the object

shouldManage - if true, manage the pointer

Returns:

a new java instance of the underlying pointer

get

public double get()

Gets the value

Returns:

current value

getName

public java.lang.String getName()

Gets the name of the variable

Returns:

name of the variable within the context

set

public void set(double value)

Sets the value

Parameters:

value - new value

setName

public void setName(KnowledgeBase kb,
                    java.lang.String name)

Sets the name and knowledge base being referred to

Parameters:

kb - the knowledge base that contains the name

name - the variable name

setName

public void setName(Variables vars,
                    java.lang.String name)

Sets the name and knowledge base being referred to

Parameters:

vars - the variables facade that contains the name

name - the variable name

setSettings

public void setSettings(UpdateSettings settings)

Sets the settings for updating variables in the Knowledge Base

Parameters:

settings - the settings to use for updating the Knowledge Base

modify

public void modify()

Mark the value as modified. The Double retains the same value but will resend its value as if it had been modified.

isTrue

public boolean isTrue()

Returns true if the container evaluates to true

Returns:

true if container has all true values

isFalse

public boolean isFalse()

Returns true if the container evaluates to false

Returns:

true if container has any false values or is uninitialized

toDouble

public double toDouble()

Converts the value to a double

Returns:

current double value

toLong

public long toLong()

Converts the value to a long

Returns:

current long value

toString

public java.lang.String toString()

Converts the value to a string

Overrides:

toString in class MadaraJNI

Returns:

current string value

()

free

public void free()

Deletes the C instantiation. To prevent memory leaks, this must be called before an instance gets garbage collected

finalize

protected void finalize()
                 throws java.lang.Throwable

Cleans up underlying C resources

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable - necessary for override but unused
