Method Details

transform

public <T,
K> java.util.Map<T,K> transform(java.util.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

transform

public <T,
K,
R,
V> java.util.Map<R,V> transform(java.util.Map<T,K> sourceMap,
BeanTransformer beanTransformer,
java.lang.Class<R> targetKeyType,

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

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

Returns:

a copy of the source object into the destination object

transform

public <T,
K> java.util.Map<T,K> transform(java.util.Map<T,K> sourceMap)

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

public <T,
K,
R,
V> java.util.Map<R,V> transform(java.util.Map<T,K> sourceMap,
java.lang.Class<R> targetKeyType,
java.lang.Class<V> targetElemType)
