Class ScopedParameterResolver

java.lang.Object

com.tangosol.config.expression.ScopedParameterResolver

All Implemented Interfaces:

ParameterResolver, ExternalizableLite, PortableObject, Serializable

public class ScopedParameterResolver
extends Object
implements ParameterResolver, ExternalizableLite, PortableObject

A ScopedParameterResolver is a ParameterResolver implementation that provides the ability to "scope" Parameter definitions to either an inner (wrapped) or outer ParameterResolver, such that those being defined in the outer ParameterResolver hide those (of the same name) in the inner (wrapped) ParameterResolver.

For example: Parameter "A" defined in the outer ParameterResolver will override and thus "hide" Parameter "A" that is defined in the inner ParameterResolver.

Constructor Detail

ScopedParameterResolver

public ScopedParameterResolver()

Default constructor needed for serialization.

ScopedParameterResolver

public ScopedParameterResolver(ParameterResolver resolver)

Construct a ScopedParameterResolver given the specified inner ParameterResolver.

Parameters:

resolver - the inner ParameterResolver

Method Detail

resolve

public Parameter resolve(String sName)

Obtains the specified named Parameter.

Specified by:

resolve in interface ParameterResolver

Parameters:

sName - the name of the Parameter

Returns:

the Parameter or null if the Parameter can't be resolved

add

public void add(Parameter parameter)

Adds the specified Parameter to the outer ParameterResolver.

Parameters:

parameter - the Parameter to add

getDescription

protected String getDescription()

Return a human-readable String representation of this class.

Returns:

the description of this class

readExternal

public void readExternal(DataInput in)
                  throws IOException

Restore the contents of this object by loading the object's state from the passed DataInput object.

Specified by:

readExternal in interface ExternalizableLite

Parameters:

in - the DataInput stream to read data from in order to restore the state of this object

Throws:

IOException - if an I/O exception occurs

NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into

writeExternal

public void writeExternal(DataOutput out)
                   throws IOException

Save the contents of this object by storing the object's state into the passed DataOutput object.

Specified by:

writeExternal in interface ExternalizableLite

Parameters:

out - the DataOutput stream to write the state of this object to

Throws:

IOException - if an I/O exception occurs

readExternal

public void readExternal(PofReader reader)
                  throws IOException

Restore the contents of a user type instance by reading its state using the specified PofReader object.

Specified by:

readExternal in interface PortableObject

Parameters:

reader - the PofReader from which to read the object's state

Throws:

IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter writer)
                   throws IOException

Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Specified by:

writeExternal in interface PortableObject

Parameters:

writer - the PofWriter to which to write the object's state

Throws:

IOException - if an I/O error occurs
