Method Detail

copyProperties

public static void copyProperties(java.lang.Object dest,
                  java.lang.Object origin,
                  PojoUtils.FieldNaming field_naming)

Copy properties "of the same name" from one POJO to the other. If the fields are named consistently (both sides have fields named "_foo" and/or "bar") this acts like Apache Commons PojoUtils.copyProperties(). If one side has leading underscores and the other does not then the names are conformed according to the field_naming parameter. It is also able to map fields between external types like Schema to their corresponding internal types.

Parameters:

dest - Destination POJO

origin - Origin POJO

field_naming - Are the fields named consistently, or does one side have underscores?

copyProperties

public static void copyProperties(java.lang.Object dest,
                  java.lang.Object origin,
                  PojoUtils.FieldNaming field_naming,
                  java.lang.String[] skip_fields)

Copy properties "of the same name" from one POJO to the other. If the fields are named consistently (both sides have fields named "_foo" and/or "bar") this acts like Apache Commons PojoUtils.copyProperties(). If one side has leading underscores and the other does not then the names are conformed according to the field_naming parameter.

Parameters:

dest - Destination POJO

origin - Origin POJO

field_naming - Are the fields named consistently, or does one side have underscores?

skip_fields - Array of origin or destination field names to skip

copyProperties

public static void copyProperties(java.lang.Object dest,
                  java.lang.Object origin,
                  PojoUtils.FieldNaming field_naming,
                  java.lang.String[] skip_fields,
                  java.lang.String[] only_fields)

Copy properties "of the same name" from one POJO to the other. If the fields are named consistently (both sides have fields named "_foo" and/or "bar") this acts like Apache Commons PojoUtils.copyProperties(). If one side has leading underscores and the other does not then the names are conformed according to the field_naming parameter.

Parameters:

dest - Destination POJO

origin - Origin POJO

field_naming - Are the fields named consistently, or does one side have underscores?

skip_fields - Array of origin or destination field names to skip

only_fields - Array of origin or destination field names to include; ones not in this list will be skipped
