Method Detail

transform

<T,K> Map<T,K> transform(Map<T,K> sourceMap)

Copies all properties from a map to a new one applying the transformation function and mappings defined.

Type Parameters:

T - the key object type in the source map

K - the elem object type in the source map

Parameters:

sourceMap - the source map

Returns:

a copy of the source object into the destination object

Throws:

IllegalArgumentException - if any parameter is invalid

transform

<T,K> Map<T,K> transform(Map<T,K> sourceMap,
                                     BeanTransformer beanTransformer)

Copies all properties from a map to a new one applying the transformation function and mappings defined.

Type Parameters:

T - the key object type in the source map

K - the elem object type in the source map

Parameters:

sourceMap - the source map

beanTransformer - the bean transformer to use for the map elements transformation

Returns:

a copy of the source object into the destination object

Throws:

IllegalArgumentException - if any parameter is invalid

transform

<T,K,R,V> Map<R,V> transform(Map<T,K> sourceMap,
                                                     Class<R> targetKeyType,
                                                     Class<V> targetElemType)

Copies all properties from a map to a new one applying the transformation function and mappings defined.

Type Parameters:

T - the key object type in the source map

K - the elem object type in the source map

R - the key object type in the target map

V - the elem object type in the target map

Parameters:

sourceMap - the source map

targetKeyType - the key type in the target map

targetElemType - the elem type in the target map

Returns:

a copy of the source object into the destination object

Throws:

IllegalArgumentException - if any parameter is invalid

transform

<T,K,R,V> Map<R,V> transform(Map<T,K> sourceMap,
                                                     BeanTransformer beanTransformer,
                                                     Class<R> targetKeyType,

Type Parameters:

T - the key object type in the source map

K - the elem object type in the source map

R - the key object type in the target map

V - the elem object type in the target map

Parameters:

sourceMap - the source map

beanTransformer - the bean transformer to use for the map elements transformation

targetKeyType - the key type in the target map

targetElemType - the elem type in the target map

withKeyTransformer

MapTransformer withKeyTransformer(FieldTransformer... keyFieldTransformer)

Initializes the transformer functions to apply on a Map key. The transformer function returns directly the field value.

Parameters:

keyFieldTransformer - the fields transformer function

Returns:

the Transformer instance

resetKeyTransformer

void resetKeyTransformer()

Removes all the configured key transformer.
