Exception2ExceptionTransformer

public Exception2ExceptionTransformer()

Method Detail

getSourceDataBinding

public java.lang.String getSourceDataBinding()

Description copied from interface: Transformer

Get the source type that this transformer transforms data from. The type is used as the key when the transformer is registered with TransformerRegistry.

Specified by:

getSourceDataBinding in interface Transformer

Overrides:

getSourceDataBinding in class BaseTransformer<java.lang.Throwable,java.lang.Throwable>

Returns:

A key identifying the source type

getTargetDataBinding

public java.lang.String getTargetDataBinding()

Description copied from interface: Transformer

Get the target type that this transformer transforms data into. The type is used as the key when the transformer is registered with TransformerRegistry.

Specified by:

getTargetDataBinding in interface Transformer

Overrides:

getTargetDataBinding in class BaseTransformer<java.lang.Throwable,java.lang.Throwable>

Returns:

A key identifying the target type

setMediator

public void setMediator(Mediator mediator)

Parameters:

mediator - the mediator to set

getSourceType

protected java.lang.Class<java.lang.Throwable> getSourceType()

Specified by:

getSourceType in class BaseTransformer<java.lang.Throwable,java.lang.Throwable>

See Also:

BaseTransformer.getSourceType()

getTargetType

protected java.lang.Class<java.lang.Throwable> getTargetType()

Specified by:

getTargetType in class BaseTransformer<java.lang.Throwable,java.lang.Throwable>

See Also:

BaseTransformer.getTargetType()

getWeight

public int getWeight()

Description copied from interface: Transformer

Get the cost of the transformation. The weight can be used to choose the most efficient path if there are more than one available from the source to the target.

Specified by:

getWeight in interface Transformer

Overrides:

getWeight in class BaseTransformer<java.lang.Throwable,java.lang.Throwable>

Returns:

An integer representing the cost of the transformation

See Also:

Transformer.getWeight()

transform

public java.lang.Throwable transform(java.lang.Throwable source,
                                     TransformationContext context)

Description copied from interface: PullTransformer

Transform source data into the result type.

Specified by:

transform in interface PullTransformer<java.lang.Throwable,java.lang.Throwable>

Parameters:

source - The source data

context - The context for the transformation

Returns:

The transformed result

setFaultExceptionMapper

public void setFaultExceptionMapper(FaultExceptionMapper faultExceptionMapper)
