Method Detail

fromHost

public FromHostPrimitiveResult<T> fromHost(Class<T> javaClass,
                                           CobolContext cobolContext,
                                           byte[] hostData,
                                           int start)

Description copied from class: CobolPrimitiveType

Convert mainframe data into a Java object.

Specified by:

fromHost in class CobolPrimitiveType<T extends Number>

Parameters:

javaClass - target java type

cobolContext - host COBOL configuration parameters

hostData - the byte array containing mainframe data

start - the start position for the expected type in the byte array

Returns:

the conversion results, including the mainframe value as a java object if conversion succeeded

valueOf

public static <D extends Number> D valueOf(Class<D> clazz,
                                           Float value)

isValid

public boolean isValid(Class<T> javaClass,
                       CobolContext cobolContext,
                       byte[] hostData,
                       int start)

Description copied from class: CobolPrimitiveType

Check if a byte array contains valid mainframe data for this type characteristics.

Specified by:

isValid in class CobolPrimitiveType<T extends Number>

Parameters:

javaClass - target java type

cobolContext - host COBOL configuration parameters

hostData - the byte array containing mainframe data

start - the start position for the expected type in the byte array

Returns:

true if the byte array contains a valid type

getBytesLen

public int getBytesLen()

Description copied from class: CobolPrimitiveType

Determine the length in bytes of the mainframe representation of this type.

Specified by:

getBytesLen in class CobolPrimitiveType<T extends Number>

Returns:

the size in bytes needed to store this type
