table

protected java.util.Map<java.lang.String,PostfixMathCommandI> table
Constructor Detail

FunctionTable

public FunctionTable()
Method Detail

init

public void init(Jep jep)
Description copied from interface: JepComponent
Initialize the component. This methods is called whenever a component is added to Jep. Hence it allows components to keep track of the other components they may rely on.

Specified by:
init in interface JepComponent
Parameters:
jep - the current Jep instance

getFunction

public PostfixMathCommandI getFunction(java.lang.String name)

addFunction

public PostfixMathCommandI addFunction(java.lang.String name,
                                       PostfixMathCommandI pfmc)

clear

public void clear()

entrySet

public java.util.Set<java.util.Map.Entry<java.lang.String,PostfixMathCommandI>> entrySet()

isEmpty

public boolean isEmpty()

keySet

public java.util.Set<java.lang.String> keySet()

size

public int size()

values

public java.util.Collection<PostfixMathCommandI> values()

containsKey

public boolean containsKey(java.lang.String key)

containsValue

public boolean containsValue(PostfixMathCommandI value)

remove

public PostfixMathCommandI remove(java.lang.String key)

getLightWeightInstance

public JepComponent getLightWeightInstance()
Description copied from interface: JepComponent
Gets a light-weight instance suitable for using in multiple threads.

Specified by:
getLightWeightInstance in interface JepComponent
Returns:
this

shallowCopy

public FunctionTable shallowCopy()
Returns a new shallow copy of this function table. The entries in the table refer to the the same instances of the postfix math commands. If sub-classes use pfmc's which are not thread safe they should override this methods and set a new instance for the table.

Returns:
a new shallow copy of this function table

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object
