Class OperatorSourceWrapper

java.lang.Object
hussam.math.operations.dataBase.OperatorSourceImpl
hussam.math.operations.dataBase.OperatorSourceWrapper

All Implemented Interfaces:

OperatorSource

Direct Known Subclasses:

DynamicOperatorSourceWrapper

public class OperatorSourceWrapper
extends OperatorSourceImpl

This DataSource wrapps a Datasource and gives the user means to access the both sources without changing the content of the base source. Use this whenever you want to have your own Source without having to build everything.

For example,
 OperatorSourceImpl mySource=new OperatorSourceWrapper(OperatorFactoryDB.getInstance());
 mySOurce.addFunction(..); //adds the function to your source.
 mySource.getFunction(..); //gets the function from your source or the inner source OperatorFactory

OperatorSourceWrapper

public OperatorSourceWrapper(OperatorSource source)

Construcs a new OperatorSource with the the given sub source.

Parameters:

source - The inner source to be inserted.

getFunctionFactory

public OperatorFactory<Function> getFunctionFactory(java.lang.String name)

Returns the factory for this Function. First it seraches for the Factory inside this Source. If it does not find it, it will search the sub source inserted in this wrapper.

Specified by:

getFunctionFactory in interface OperatorSource

Overrides:

getFunctionFactory in class OperatorSourceImpl

Parameters:

name - The name of the function.

Returns:

The function factory.

getOperandFactory

public OperatorFactory<Operand> getOperandFactory(java.lang.String name)

Returns the Operand factory by this name. First it serachs for the factory inside this source. If it does not find it, it will seach the sub source for it.

Specified by:

getOperandFactory in interface OperatorSource

Overrides:

getOperandFactory in class OperatorSourceImpl

Parameters:

name - The name of the operand.

Returns:

the operand factory.

getGlobalVariable

public Variable getGlobalVariable(java.lang.String name)

Returns the Global Variable by this name. First it searchs this source. if it does not find it, it will search the sub source inserted in the constructor.

Specified by:

getGlobalVariable in interface OperatorSource

Overrides:

getGlobalVariable in class OperatorSourceImpl

Parameters:

name - the name of the Global Variable.

Returns:

The variable.

getFunctionFactories

public java.util.Map<java.lang.String,OperatorFactory<Function>> getFunctionFactories()

Returns all Factories in both this source and the sub source. First it adds all the inner source factories, Then it adds this function factories. If there is a sharred function name in both inner and this source, The function factory from this source will be added.

Specified by:

getFunctionFactories in interface OperatorSource

Overrides:

getFunctionFactories in class OperatorSourceImpl

Returns:

a map of all factories.

getGlobalVariables

public java.util.Map<java.lang.String,Variable> getGlobalVariables()

Returns all Global Variable in this source, and inside the sub source. First it adds all the inner source global variables, Then it adds this source's global variables. If there is a sharred variable name in both inner and this source, The global variable from this source will be added.

Specified by:

getGlobalVariables in interface OperatorSource

Overrides:

getGlobalVariables in class OperatorSourceImpl

Returns:

a map of all Global Variables.

getOperandFactories

public java.util.Map<java.lang.String,OperatorFactory<Operand>> getOperandFactories()

Returns all Factories in this source and in the sub source. First it adds all the inner source factories, Then it adds this operand factories. If there is a sharred operand name in both inner and this source, The operand factory from this source will be added.

Specified by:

getOperandFactories in interface OperatorSource

Overrides:

getOperandFactories in class OperatorSourceImpl

Returns:

a map of all Factories.

toString

public java.lang.String toString()

Overrides:

toString in class OperatorSourceImpl

getInnerSource

public OperatorSource getInnerSource()
