Interface GraphTransformer

All Known Implementing Classes:

AbstractGraphTransformer, BidiGraphTransformer, DefaultGraphTransformer, YObjectGraphTransformer

public interface GraphTransformer

Transforms a graph or a subgraph from a source into a target representation. For each single transformation a GraphContext is used. If no GraphContext is passed, an appropriate one gets created automatically.

A GraphContext can be created manually with createGraphContext(). Such context can be used to customize transformation behavior for exactly one transformation process. After that context can still be used to fetch some statistic values but not for a second transformation process again.

<T> T	transform(GraphContext ctx, java.lang.Object source) Calls transform(GraphContext, Object, Object) without a specific target.
<T> T	transform(GraphContext ctx, java.lang.Object source, T target) Transforms a source object into a target one.
<T> T	transform(java.lang.Object source) Calls transform(GraphContext, Object, Object) with no specific context and no given target.
<T> T	transform(java.lang.Object source, T target) Calls transform(GraphContext, Object, Object) with no specific context.

Method Detail

transform

<T> T transform(java.lang.Object source)

Calls transform(GraphContext, Object, Object) with no specific context and no given target.

Type Parameters:

T -

Parameters:

source - source graph

Returns:

target graph

transform

<T> T transform(java.lang.Object source,
                T target)

Calls transform(GraphContext, Object, Object) with no specific context.

Type Parameters:

T -

Parameters:

source - source graph

target - target graph or null

Returns:

target graph

transform

<T> T transform(GraphContext ctx,
                java.lang.Object source)

Calls transform(GraphContext, Object, Object) without a specific target.

Type Parameters:

T -

Parameters:

ctx - GraphContext

source - source graph

Returns:

target graph

transform

<T> T transform(GraphContext ctx,
                java.lang.Object source,
                T target)

Transforms a source object into a target one. Source is the graph (starting from root or any child node) which shall be transformed. If no context is passed, a default one will be created. If no target is passed, an appropriate one will be created. Return value is always 'target' regardless whether it was already passed or internally created.

Type Parameters:

T -

Parameters:

source - source graph

target - target graph or null

Returns:

target graph

createGraphContext

GraphContext createGraphContext()

Creates a GraphContext. Such context can be used to customize transformation behavior or fetch some statistics after transformation.

Returns:

GraphContext.

setNodeValueCreatedListener

void setNodeValueCreatedListener(NodeValueCreatedListener listener)
