Method Detail

fromBytes

public Object fromBytes(commonj.sdo.Property targetProperty,
                        byte[] value)

Converts the given value from bytes based on data type and cardinality information for the given property. For 'many' or multi-valued properties, if the SDO Java type for the property is not already String, the value is first converted from a String using the SDO conversion which uses java.util.Arrays formatting, resulting in an array of primitive types. For non 'many' or singular properties, only the HBase Bytes utility is used.

Parameters:

targetProperty - the property

value - the bytes value

Returns:

the converted object

Throws:

IllegalArgumentException - if the given property is not a data type property

toBytes

public byte[] toBytes(commonj.sdo.Property sourceProperty,
                      Object value)

Converts the given value to bytes based on data type and cardinality information for the given property. For 'many' or multi-valued properties, if the SDO Java type for the property is not already String, the value is first converted to String using the SDO conversion which uses java.util.Arrays formatting. For non 'many' or singular properties, only the HBase Bytes utility is used.

Parameters:

sourceProperty - the source property

value - the value

Returns:

the bytes

Throws:

IllegalArgumentException - if the given property is not a data type property
