Method Detail

toHost

int toHost(ICobolBinaryBinding ce,
           byte[] hostTarget,
           int offset)
           throws HostException

Converts an element java value to a host representation stored in host buffer.

Parameters:

ce - Cobol element descriptor

hostTarget - Target host buffer

offset - Offset in the target host buffer

Returns:

the new offset after host buffer has been updated

Throws:

HostException - if conversion fails

toHost

int toHost(ICobolArrayBinaryBinding ce,
           byte[] hostTarget,
           int offset,
           int currentOccurs)
           throws HostException

Converts an array of java values to a host representation stored in host buffer.

Parameters:

ce - Cobol array descriptor

hostTarget - Target host buffer

offset - Offset in the target host buffer

currentOccurs - actual number of items in array

Returns:

the new offset after host buffer has been updated

Throws:

HostException - if conversion fails

fromHost

int fromHost(ICobolBinaryBinding ce,
             byte[] hostSource,
             int offset)
             throws HostException

Converts an element Cobol value from a host buffer to a java value.

Parameters:

ce - Cobol element descriptor

hostSource - Source host buffer

offset - Offset in the source host buffer

Returns:

the new offset after host buffer has been read

Throws:

HostException - if conversion fails

fromHost

int fromHost(ICobolArrayBinaryBinding ce,
             byte[] hostSource,
             int offset,
             int currentOccurs)
             throws HostException

Converts an array of Cobol values from a host buffer to a java array.

Parameters:

ce - Cobol array descriptor

hostSource - Source host buffer

offset - Offset in the source host buffer

currentOccurs - actual number of items in array

Returns:

the new offset after host buffer has been read

Throws:
