方法详细资料

toInternal

public I toInternal(I external)

从接口复制的说明: DataStructureConverter

Converts to internal data structure.

Note: Parameter must not be null. Output must not be null.

指定者:

toInternal 在接口中 DataStructureConverter<I,I>

toExternal

public I toExternal(I internal)

从接口复制的说明: DataStructureConverter

Converts to external data structure.

Note: Parameter must not be null. Output must not be null.

指定者:

toExternal 在接口中 DataStructureConverter<I,I>

isIdentityConversion

public boolean isIdentityConversion()

从接口复制的说明: DataStructureConverter

Returns whether this conversion is a no-op.

An identity conversion means that the type is already an internal data structure.

指定者:

isIdentityConversion 在接口中 DataStructureConverter<I,I>
